Concept
SMBC private banking is the private client business of the SMFG group (Sumitomo Mitsui) in two places: SMBC's Private Advisory Division (since 2007 — for business owners, succession and capital) and SMBC Trust Bank, which absorbed Société Générale's Japanese private bank (2013) and Citibank Japan's retail business (2015, the PRESTIA brand). Type: divisions inside a megagroup (SMFG: assets of ¥306tn); the SMFG president is Toru Nakashima, and SMBC Trust Bank has been led by Kotaro Hagiwara since 2024. PRESTIA is a rare-in-Japan offering with full English support, but for residents only.
History and evolution
SMBC was formed in the 2001 merger; the trust bank followed the line Chemical Trust → Chase Trust → SG Private Banking Japan → SMBC Trust Bank (October 2013). In November 2015 Citibank Japan's retail business was folded in (~740,000 customers, ¥2.44tn of deposits) — creating PRESTIA. In June 2025 the group announced a joint venture with SBI in wealth management (SMBC Group 60%, SBI Group 40%) as the asset-management service of Olive's new top tier, Olive Infinite; the company, Olive Consulting, was established in August 2025 and began operating in May 2026.
Scale: SMBC Trust Bank deposits of ¥3.71tn (March 2025), assets including trust accounts of ¥4.58tn; the bank claims Japan's #1 foreign-currency deposit balance; group FY3/2025 profit of ¥1.18tn (+22%).
Regulation
- FSA / Bank of Japan — SMBC, SMBC Trust Bank and SMBC Nikko Securities;
- SMBC Trust Bank has no overseas branches — the network is domestic (PRESTIA); the group's overseas points serve the corporate perimeter.
Source of funds and compliance
For foreign residents: a residence card with a current address and at least three months' remaining stay; for fresh cards, proof of employment or six months' residence; no applications from overseas addresses. Private banking adds the source-of-funds file. No public FSA enforcement against SMBC Trust Bank under SMBC ownership (2013–2026) was identified; the group episode — the FSA orders against SMBC Nikko (October 2022, market manipulation) — concerns the brokerage arm, not private banking.
Who it serves
- PRESTIA (official statuses): Digital Gold — from ¥3m under management; Gold — a total relationship from ¥10m plus ¥3m under management; Gold Premium — from ¥50m plus ¥10m;

- SMBC Private Advisory: no published threshold; per industry data — ~¥300–500m (unofficial);

Entities and booking centres
| Jurisdiction | Legal entity | Format and supervisor | Role for the client |
|---|---|---|---|
| Japan | SMBC (PA Division) + SMBC Trust Bank (+ PRESTIA) | FSA | domestic market; the trust bank has no overseas branches |
The group's international perimeter (SMBC, Nikko) serves corporate and institutional clients, not private banking.
Strengths
- the only megabank with in-house testamentary trusts;
- PRESTIA — a full English perimeter for foreign residents, the Citibank Japan heritage;
- a two-layer model: affluent retail PRESTIA plus genuine private banking;
- SMFG's group power and the new SBI joint venture, Olive Consulting.
Where it does not fit
- non-residents: an account requires a Japanese address;
- those seeking a published private-banking threshold — none exists (only the PRESTIA statuses are published);
- clients needing international booking: the trust bank has no overseas network;
- portfolios centred on crypto assets.
SMBC private banking is Japan's two-layer model: PRESTIA for affluent residents and a trust bank for large fortunes with an inheritance core; by construction it has no international map.
Q/A
Entry and model
What minimum capital is required?
Only the PRESTIA statuses are published: Digital Gold from ¥3m under management, Gold from ¥10m total, Gold Premium from ¥50m. The true private-banking threshold at SMBC Trust Bank is unpublished (publications cite ~¥100m), and the Private Advisory Division publishes none either (industry data points to ~¥300–500m).
Can a foreigner open an account?
Yes, if resident in Japan: PRESTIA requires a residence card with a current address and at least three months' remaining stay; fresh residents need proof of employment or six months' residence. PRESTIA is a rare fully English banking service in Japan: branches (Akasaka, Hiroo), phone, online and documents in English. Non-residents cannot open an account.
What does deposit insurance cover?
The DIC — up to ¥10m of principal plus interest on yen deposits per depositor; foreign-currency deposits are not covered. Trust assets and securities remain the client's property.
History
Where did PRESTIA come from?
From the purchase of Citibank Japan's retail business: in November 2015 SMBC Trust Bank absorbed ~740,000 customers, ¥2.44tn of deposits and the branch network; the PRESTIA brand launched at the same time. The trust bank itself was previously Société Générale's Japanese private bank (acquired in 2013).
What is the SBI joint venture?
June 2025: an SMFG–SBI wealth-management joint venture (SMBC Nikko 30%, SBI Securities 30%, SMBC 20%, SMFG and SBI 10% each); the company, Olive Consulting, was established in August 2025 and has operated since May 2026 as the asset-management service of Olive Infinite. It widens the shelf rather than changing the private-banking model.
