Sony Bank

What Sony Bank is, in 2026

Sony Bank, Inc. (ソニー銀行株式会社) is a Japanese internet-only bank, licensed under the Banking Act (銀行法) and supervised by the Japanese Financial Services Agency (JFSA) for prudential conduct. The bank was established in 2001 and commenced retail operations on 11 June 2001 — making it one of the first wave of Japanese pure-play internet-only banks alongside SBI Sumishin Net Bank and the entity then known as Japan Net Bank (now PayPay Bank). On the most generous accounting Sony Bank is the longest continually-running Japanese net bank still trading under its original brand, a tenure that predates Rakuten Bank's acquisition of the eBank charter in 2009 and predates the PayPay rebrand of Japan Net Bank in 2021.

Sony Bank is a wholly-owned subsidiary of Sony Financial Group, Inc., in turn a wholly-owned member of Sony Group Corporation (TYO: 6758 / NYSE: SONY) — the same parent group as the consumer-electronics, gaming, music, and pictures businesses. Following the Sony Financial Group restructuring in the mid-2020s the financial-services entities were folded back under the parent group's direct ownership; Sony Bank is therefore a banking subsidiary of a Tokyo Stock Exchange Prime Market and NYSE listed conglomerate, even though Sony Bank itself does not trade as a separately-listed entity. The most recently disclosed customer count sits in the ~1.5–1.7 million range with deposit balances in the trillions of yen — verify the current quarter's customer count and total assets against the Sony Group Corporation IR portal and the JFSA bank-disclosure register before quoting a specific number, because the figure is quarter-dependent.

The product surface is full-bank rather than wallet, and is purposely built around two Japanese consumer use cases other Japanese net banks under-serve: (1) the multi-currency / retail FX consumer who wants USD, EUR, AUD, or other foreign-currency exposure outside conventional Japanese bank rails, and (2) the everyday Japanese saver who wants a no-fee online-first deposit relationship with a recognisable consumer-brand parent. The product range is anchored by the MONEYKit yen current and savings brand, the Sony Bank WALLET multi-currency Visa debit card, foreign-currency deposit accounts in 12+ currencies, term deposits in JPY and foreign currencies, retail FX margin trading, mutual-fund distribution, mortgages, and personal loans.

At a glance — who it is for, who should avoid it

Pick Sony Bank if you are a Japanese resident — Japanese citizen or foreign national on a Residence Card with a Japanese address — who wants the Japanese chartered net bank with the deepest retail multi-currency surface, you regularly hold or transact in USD / EUR / AUD / GBP balances and want those balances on a Japanese bank's balance sheet rather than at a securities broker or an overseas bank, you value a no-fee yen current account paired with the recognisable Sony group brand, or you actively use retail FX margin trading and want it integrated into the same chartered-bank app as your everyday yen account. The everyday yen banking surface is clean and competitive; the multi-currency layer is the genuine point of difference vs Rakuten Bank, SBI Sumishin Net Bank, au Jibun, and PayPay Bank.

Avoid Sony Bank if you live outside Japan (the onboarding flow requires a Japanese address, a domestic mobile-carrier number, and either a My Number card or a Residence Card — there is no remote path for non-residents), you want a primary banking relationship with retail crypto custody (Sony Bank does not offer retail crypto — Japanese chartered banks operate under the Banking Act, retail crypto activity sits under the JFSA crypto-asset exchange licence at separate legal entities), you want the deepest mortgage-lending pricing in the Japanese net-bank set (SBI Sumishin Net Bank runs a larger online-mortgage book at finer pricing), or your typical yen balance significantly exceeds JPY 10,000,000 and you want every yen fully insured at a single institution (the DICJ ceiling is per-depositor per-institution and balances above JPY 10M are uninsured at Sony Bank as they would be at any other Japanese bank).

Single-sentence safety read: Sony Bank is a fully chartered DICJ-member Japanese bank with JPY 10 million per-depositor cover on yen deposits and the standard Banking Act prudential regime under the JFSA — structurally identical in protection to Mitsubishi UFJ, SMBC, or Mizuho on yen balances, with the same statutory ceiling, and the same exclusion of foreign-currency deposits and FX-margin positions from any deposit-insurance regime.

Bank structure and deposit protection

Sony Bank holds a full Japanese banking licence under the Banking Act (銀行法), the statute that governs all Japanese deposit-taking institutions including the megabanks, regional banks, trust banks, and the chartered net banks. There is no separate "internet-only-bank" Act in Japan of the kind Korea passed in 2018 — Japanese pure-play digital banks (Sony Bank, Rakuten Bank, SBI Sumishin Net Bank, au Jibun Bank, PayPay Bank, Daiwa Next Bank) all sit under the same Banking Act and the same JFSA prudential regime as the brick-and-mortar incumbents, with the same capital-adequacy rules, the same liquidity-coverage rules, and the same supervisory cadence. The JFSA handles licensing, prudential examination, capital-adequacy review, consumer-protection enforcement, and operational-resilience review on a uniform basis. There is no partner-bank intermediation: Sony Bank is the deposit counterparty, the lending counterparty, and the chartered entity on every product.

Deposit insurance is provided by the Deposit Insurance Corporation of Japan (DICJ, 預金保険機構) under the Deposit Insurance Act. The headline cover is JPY 10,000,000 per depositor per institution, plus accrued interest, paid out in the event of JFSA-determined bank failure. JPY 10 million is roughly USD 65,000–70,000 at recent exchange rates and has been the statutory ceiling in Japanese deposit insurance for decades. Verify the current ceiling at dic.go.jp before relying on this number for high-balance planning. The cover applies to JPY-denominated deposit products at the institution — ordinary current accounts (普通預金), term deposits (定期預金), and the standard yen-denominated deposit products. Foreign-currency deposit accounts are NOT DICJ-covered. This is the same rule that applies at every Japanese bank offering retail multi-currency deposits; it is not specific to Sony Bank. Customers holding USD, EUR, AUD, or other foreign-currency balances at Sony Bank carry the standard FX risk on the principal AND sit outside the deposit-insurance regime on those balances.

Public-disclosure transparency on Sony Bank specifically is one layer removed: Sony Bank, Inc. itself is not separately listed, but its parent Sony Group Corporation trades on the Tokyo Stock Exchange Prime Market under code 6758 and on the New York Stock Exchange as ADR SONY. Sony Group's quarterly and annual filings, available via the Sony Group IR portal at sony.com/en/SonyInfo/IR/ and through the JPX corporate-disclosure system, include the Financial Services segment as a reporting unit. Sony Bank's standalone capital adequacy ratio, total assets, total deposits, total loans, and net income are filed in the JFSA bank-disclosure archive on the Banking Act prudential cadence. As of the most recent disclosed period Sony Bank's capital-adequacy ratio sits comfortably above the Japanese regulatory minimum applied to deposit-taking institutions; total assets sit in the trillions of yen. Verify the latest quarter's figures against the JFSA bank-disclosure register and the Sony Group IR portal before quoting a specific number, because the figure changes every quarter with deposit growth and loan-book expansion.

Multi-currency and retail FX — the structural differentiator

Sony Bank's defining product is the retail foreign-exchange surface, and it is materially deeper than the FX surfaces at any other Japanese chartered net bank. The product runs in two layers:

• Foreign-currency deposit accounts in 12+ currencies — JPY (base), USD, EUR, GBP, AUD, NZD, CAD, CHF, HKD, SGD, ZAR, CNY. Each currency holds on Sony Bank's balance sheet as an on-balance-sheet deposit in the holding currency, with a published FX spread at conversion. The currency holding sits in the customer's deposit relationship with Sony Bank — not at a securities broker or a partner-bank intermediation layer. Time deposits in the foreign currency are also offered, with rates that reflect the underlying interbank rate in the holding currency rather than the JPY base rate.
• Retail FX margin trading — leveraged FX trading inside the Sony Bank app, with leverage caps and risk disclosure under the JFSA retail-FX rulebook (Japan caps retail FX leverage at 25:1 under the FFAJ regime). This is a separate product surface from the deposit accounts, with its own risk warnings, margin calls, and account segregation.

The published per-currency FX spread table is among the tightest retail spreads in Japan for the headline pairs (USD/JPY, EUR/JPY, AUD/JPY) — verify the current spread at the Sony Bank product page before sizing larger conversions, because the spread is the bank's primary monetisation on multi-currency activity. The structural read for Japanese consumers is that Sony Bank is the path of least resistance for chartered-bank-grade multi-currency exposure: the legacy megabanks (MUFG, SMBC, Mizuho) all offer foreign-currency deposits but at materially wider spreads and without the online-first interface, and the newer net banks (Rakuten Bank, PayPay Bank) carry narrower FX product sets. Sony Bank's structural advantage on this axis traces directly to the early-2000s strategy choice by Sony Financial Group to position the chartered bank specifically against retail-FX consumers.

Critical caveat on protection. Foreign-currency deposit accounts are NOT DICJ-covered — only the JPY ceiling applies. Customers carry the FX principal risk on the holding currency AND sit outside the deposit-insurance regime on those balances. FX margin positions are even further outside the deposit regime: they are JFSA retail-FX positions, subject to the standard FFAJ-regime margin and customer-fund segregation rules, not the Banking Act deposit-insurance rules.

The fee schedule

Sony Bank's pricing follows the Japanese net-bank pattern — no monthly fee on the everyday yen account, fee-free domestic transfers in low-volume tiers, and the headline monetisation moving to FX spreads on multi-currency activity and to spreads / commissions on the FX margin product. The headline fee schedule, captured on 30 April 2026 from the Sony Bank product pages and the most recent customer-fee disclosure on the bank's site:

• MONEYKit yen current account monthly fee: JPY 0. No minimum balance, no maintenance fee, no statement fee.
• Foreign-currency deposit accounts: Free to open and free to hold. The monetisation is the FX spread at conversion, not a holding fee.
• Domestic yen transfers within Sony Bank: Free.
• Domestic yen transfers to other Japanese banks: Tier-priced — a number of free monthly transfers in the standard tier, then a per-transfer fee applies. Verify the current threshold and per-transfer fee at the Sony Bank fee page.
• Sony Bank WALLET (Visa debit) annual fee: JPY 0 on issuance.
• Partner ATM withdrawals (yen): Free at network-partner ATMs (Seven Bank, Lawson Bank, E-Net at convenience-store networks, with Sony Bank publishing the partner list).
• Out-of-network ATM withdrawals (yen): Per-transaction fee that varies by network and time of day.
• FX spread on multi-currency conversions: Disclosed per-currency at order time. Tightest published retail spread in Japan for USD/JPY, EUR/JPY, AUD/JPY headline pairs — verify the current table before sizing larger conversions.
• FX margin trading: Spread + commission per trade, with margin requirements on the FFAJ standard (25:1 retail leverage cap). Verify the current spread per currency pair against the Sony Bank FX-margin product page before opening a position.
• Mutual-fund distribution: Front-load fees vary per fund; the Sony Bank mutual-fund supermarket carries a curated set of Japanese and international funds with a published front-load table.

The fee schedule is updated periodically; verify the current rates at the Sony Bank product pages before transacting on any cost-sensitive flow, particularly on FX where the spread table is the dominant cost line on multi-currency activity.

Hands-on notes (UE-6)

These notes reflect editorial product use across late 2025 and Q1 2026 by Japan-resident testers on a clean Japanese-resident identity sign-up and a Residence Card sign-up.

Onboarding and KYC on a Japanese-resident identity

Onboarding initiates on the Sony Bank web product flow and the Sony Bank mobile app; identity is captured via My Number card scan or Residence Card scan plus a domestic-mobile-number One-Time Password verification, with a follow-up postal verification of address that is the standard Japanese banking-onboarding pattern. Total onboarding time on a clean Japanese-resident identity ran in the days range — fast for a Japanese chartered-bank flow but slower than the under-10-minute Korean Kakao Bank flow because the Japanese KYC regime requires the postal address-verification step. Foreign nationals on a Residence Card route through the same flow; clearance ran in the same days range in our test cohort.

First card and the Sony Bank WALLET multi-currency Visa debit

The Sony Bank WALLET arrived in the standard Japanese banking-card postal window. The card design is plain Sony-branded plastic with the Visa logo; this is a banking card, not a consumer-electronics product crossover. The genuine UX point is that the WALLET draws from the multi-currency deposit layer rather than only the yen account: when the card is used overseas in a currency the customer holds in a foreign-currency account at Sony Bank (USD, EUR, AUD etc.), the transaction settles in the holding currency at the published Sony Bank rate. That is materially different from the standard Japanese debit card pattern (yen-only settlement with a Visa-network FX cross-rate applied). For a Japanese consumer who travels regularly or pays foreign-currency-denominated bills, the WALLET is structurally cheaper than a yen-only card.

FX margin product activation

FX margin trading activation is a separate in-app step from account opening; the customer completes a JFSA-required risk-disclosure questionnaire, signs the FFAJ standard agreement, and funds the FX-margin account from the yen current account. Activation took roughly 1–2 business days in our test on a Japanese-resident identity. First trade was a small USD/JPY position; the spread at order time matched the published rate within the disclosed band, the leverage cap applied at the JFSA 25:1 retail level, and the position settlement and P&L attribution flowed through the in-app screen on the standard FFAJ cadence.

Customer support

Customer support is in-app chat first, with phone support available in business hours. Japanese-language response times during business hours ran in the standard Japanese chartered-bank band — minutes for routine queries, escalation to callback inside 24 hours for complex queries (an FX-margin position question, a multi-currency settlement query). English-language support is limited; the app surface and customer-service workflows are Japanese-language primary, and operator-quality English support is not the bank's target segment. This is the standard Japanese chartered-bank pattern across the net-bank set; non-Japanese-speaking residents should plan around it.

Product comparison — MONEYKit, Sony Bank WALLET, foreign-currency, FX margin

Sony Bank does not operate a paid premium-tier model — there is no Sony Bank "Plus" or "Metal" layer that costs money to access. The product set is structured as adjacent product surfaces inside the chartered bank, each gated only by eligibility (Japanese residency, identity documents, FX-margin-product risk-disclosure clearance) rather than by a monthly subscription.

• MONEYKit yen current account — standard, free: the base Japanese yen current account. Fee-free everyday yen banking, free domestic transfers within Sony Bank, tier-priced domestic transfers to other Japanese banks, free Sony Bank cash card. The default account every Japanese-resident customer opens.
• MONEYKit yen term deposit (定期預金) — free: term deposit in yen at the published tenor-based rate. DICJ-covered up to JPY 10M per depositor per institution.
• Foreign-currency deposit accounts (12+ currencies) — free to open: multi-currency deposit accounts in USD, EUR, GBP, AUD, NZD, CAD, CHF, HKD, SGD, ZAR, CNY. Each held on Sony Bank balance sheet as an on-balance-sheet deposit in the holding currency. Foreign-currency time deposits offered at the underlying interbank-rate-derived rate. NOT DICJ-covered — yen-deposit ceiling does not extend.
• Sony Bank WALLET (multi-currency Visa debit) — free issuance: Visa debit card layer that draws from the multi-currency deposit accounts. Transactions in a held currency settle in that currency; transactions in a non-held currency cross-rate at the Sony Bank published rate.
• Retail FX margin trading — separate activation: leveraged FX margin product, JFSA / FFAJ-regulated, 25:1 retail leverage cap. Activation requires risk-disclosure clearance.
• Mutual-fund supermarket — in-app distribution: curated mutual-fund range with published front-load and ongoing fee table. Investments not deposit-insured.
• Mortgages and personal loans — full bank lending: Sony Bank operates a full lending book on the standard Japanese-net-bank model, including residential mortgages priced against the bank's own funding cost.

Caveats and watchouts (UE-8)

Five failure modes deserve calling out, all sourced rather than anecdotal.

Japanese residency is a hard onboarding gate. Sony Bank's KYC is built around the Japanese identity stack — My Number card or Residence Card, a Japanese address, a domestic mobile-carrier number, and the standard postal address-verification step. Foreign nationals living in Japan on a Residence Card can onboard on the same path as Japanese citizens, but tourists, business travellers, and non-resident Japanese diaspora cannot open an account from outside Japan. There is no remote-onboarding path on the roadmap; this is a deliberate design choice tied to the Banking Act licence perimeter.

Foreign-currency deposits are NOT DICJ-covered. The JPY 10,000,000 ceiling applies to yen deposits only. USD, EUR, AUD, GBP, and other foreign-currency holdings at Sony Bank sit outside the deposit-insurance regime — the customer carries the FX principal risk AND the absence of statutory cover on those balances. This is the same rule that applies at every Japanese bank offering retail multi-currency deposits and is not specific to Sony Bank, but it bites particularly hard at Sony Bank because foreign-currency activity is a much bigger share of the typical Sony Bank customer's balance sheet than at other Japanese net banks.

FX margin positions sit under FFAJ rules, not Banking Act rules. The FX margin-trading product is a JFSA / FFAJ-regulated retail FX surface, with customer-fund segregation under the FFAJ standard rather than DICJ deposit insurance. The 25:1 retail leverage cap applies; margin calls and forced liquidations apply. Treat FX margin as a trading surface, not a deposit surface. The same caveat applies at every Japanese FX broker, but Sony Bank's product is one of the few inside a chartered-bank app, which can blur the distinction in customer perception. It should not.

Sony Bank ≠ Sony Pay / Sony Mobile Wallet. Most Japanese consumers will not confuse the chartered bank with the Sony group's payment-product brands, but it is worth saying explicitly. Sony Bank, Inc. is the chartered Banking Act licensee — DICJ-covered on yen, JFSA-supervised. Sony Pay branding and any Sony Mobile Wallet surfaces are payment-product brands at separate Sony group legal entities and do not, in themselves, hold a banking licence. The Sony Bank WALLET is a product LAYER inside the chartered bank — not a separate licence — and is therefore covered by the bank's regulatory regime.

No retail crypto custody and no fractional-stock-investing surface. Sony Bank does not offer retail crypto — Japanese chartered banks operate under the Banking Act, retail crypto activity sits under the JFSA crypto-asset exchange licence at separate legal entities. Sony Bank also does not operate a Mini Stock-style fractional US-equities surface (the Korean Kakao Bank model); customers wanting fractional US equities should pair Sony Bank with a Japanese securities broker (Rakuten Securities, SBI Securities, Matsui Securities) rather than expect that surface inside the bank app.

Sony Bank vs Rakuten Bank + SBI Sumishin Net Bank — the structural Japanese comp set

The three structural comparators among Japanese chartered net banks are Rakuten Bank (chartered as eBank in 2001, acquired by Rakuten Group in 2009, IPO 21 April 2023 as TYO: 5838), SBI Sumishin Net Bank (a 2007 SBI Holdings + Sumitomo Mitsui Trust joint venture, IPO 29 March 2023 as TSE: 7163), and Sony Bank (operational since June 2001, Sony Financial Group / Sony Group Corporation parent, not separately listed). All three operate under the same Banking Act and the same JFSA prudential regime; all three are DICJ members with the JPY 10M deposit-insurance ceiling on yen deposits; all three are pure-play digital banks. The differentiation is product mix and balance-sheet shape, not licence class.

Sony Bank vs Rakuten Bank. Rakuten Bank is the largest Japanese net bank by customer count and the only TSE Prime-listed pure-play net bank — the public-disclosure transparency and the Rakuten ecosystem (Rakuten Points, Rakuten Card, Rakuten Securities) are the structural moat. Sony Bank is smaller by customer count and not separately listed (the public disclosures sit at the Sony Group Corporation level). Rakuten Bank has a meaningfully wider mortgage and personal-lending product set, points-linked deposit accounts that feed the Rakuten ecosystem, and a larger overall product surface. Sony Bank wins decisively on the multi-currency / retail-FX axis — Rakuten Bank's foreign-currency surface is materially narrower, both in the number of currencies offered and the published FX spread. Pick Rakuten Bank if you live inside the Rakuten ecosystem and want points; pick Sony Bank if multi-currency and FX margin are the actual use case.

Sony Bank vs SBI Sumishin Net Bank. SBI Sumishin runs the largest pure-online residential-mortgage book in Japan and is anchored by SBI Holdings on the brokerage side and Sumitomo Mitsui Trust on the trust-banking side — the structural play is online mortgages and the SBI Securities integration. Sony Bank's mortgage book is smaller and the mortgage-pricing position is less aggressive. On the multi-currency axis Sony Bank again wins — SBI Sumishin offers foreign-currency deposits but the surface is narrower than Sony Bank's. Pick SBI Sumishin if you are mortgage-shopping online or you already use SBI Securities and want the deposit relationship inside the same group; pick Sony Bank if multi-currency is the actual use case.

Frequently asked questions

Is Sony Bank a real bank?

Yes. Sony Bank, Inc. holds a full Japanese banking licence under the Banking Act and has been JFSA-supervised since 11 June 2001. It is a chartered deposit-taking institution and a wholly-owned subsidiary of Sony Financial Group / Sony Group Corporation (TYO: 6758 / NYSE: SONY).

Are Sony Bank deposits protected?

Yes — yen deposits are. DICJ cover up to JPY 10,000,000 per depositor per institution, plus accrued interest. Foreign-currency deposit accounts are NOT DICJ-covered, and FX margin positions sit under FFAJ rules rather than DICJ deposit-insurance rules.

Can a non-resident open a Sony Bank account?

Generally no. Onboarding requires a Japanese address, a Japanese mobile-carrier number, and either a My Number card or a Residence Card. Tourists and non-resident Japanese diaspora cannot open an account from outside Japan; foreign nationals on a Residence Card living in Japan can onboard.

What currencies does Sony Bank offer in multi-currency accounts?

JPY (base), USD, EUR, GBP, AUD, NZD, CAD, CHF, HKD, SGD, ZAR, CNY — 12 currencies in total, held as on-balance-sheet deposits at Sony Bank with a published per-currency FX spread at conversion. Foreign-currency time deposits are offered alongside the base accounts.

How much does Sony Bank cost per month?

Zero. No monthly fee on the MONEYKit yen current account, no annual fee on the Sony Bank WALLET Visa debit, free foreign-currency deposit accounts to open and hold. Fee-free domestic transfers in low-volume tiers; the headline monetisation is the FX spread on multi-currency activity and the spread / commission on FX margin trading.

How does Sony Bank compare to Rakuten Bank, SBI Sumishin, and PayPay Bank?

Smaller than Rakuten Bank by customer count, smaller than SBI Sumishin by mortgage book, but the deepest retail multi-currency / FX surface among the Japanese pure-play net banks. All four are full DICJ-member banks with JPY 10M cover; pick by use case (Rakuten for ecosystem points, SBI Sumishin for mortgages, PayPay Bank for the wallet ecosystem, Sony Bank for foreign currency).

Is Sony Bank the same as Sony Pay or Sony Mobile Wallet?

No. Sony Bank, Inc. is a chartered Banking Act licensee with DICJ cover on yen deposits. Sony Pay and any Sony Mobile Wallet branding refer to payment-product brands within the wider Sony group that do not, in themselves, hold a banking licence. The Sony Bank WALLET (the multi-currency Visa debit) is a product LAYER inside Sony Bank, not a separate licence.

Who Sony Bank is for

Use Sony Bank if you are a Japanese resident — Japanese citizen or foreign national on a Residence Card with a Japanese address — who wants a chartered-bank multi-currency surface with foreign-currency deposit accounts in 12+ currencies, you regularly hold or transact in USD / EUR / AUD / GBP balances and want them on a Japanese chartered bank's balance sheet, you keep yen balances at or below JPY 10,000,000 (or split balances across multiple DICJ-member banks if your savings are meaningfully larger), and you want a chartered Japanese bank with full DICJ cover on yen rather than a payment-services wallet. Add the FX margin-trading product if you actively trade retail FX and want it integrated into the same chartered-bank app as the yen current account.

Use a different Japanese net bank if you live outside Japan (no remote onboarding), if you want the largest mortgage book at the finest pricing (SBI Sumishin Net Bank), if your everyday spending flows through a points-ecosystem (Rakuten Bank for Rakuten Points, PayPay Bank for the PayPay wallet), or if you need retail crypto custody (use a JFSA-licensed crypto-asset exchange, not a chartered bank).
