Sony Bank Brand Guidelines: A 2001 Net Bank, MONEYKit and Sony Bank WALLET

A bank set up by an electronics group.

Sony Bank was set up by Sony. The bank’s own history says Sony Corporation, now Sony Group Corporation, applied to Japan’s Financial Services Agency for a preliminary review for a banking licence in January 2001, and that the review was completed in March. Sony Bank Incorporated (ソニー銀行株式会社) was established on 2 April 2001 in Minato-ku, Tokyo, and received its banking licence that month, the bank says.

It opened for business in June 2001 with a service website called MONEYKit, offering yen ordinary and time deposits, investment trusts and card loans, and a link to the ATMs of Sumitomo Mitsui Banking Corporation. Foreign-currency deposits followed in September 2001, connections with the post office ATM network in January 2002, and home loans in March 2002, according to the bank’s history.

The bank built its cash network on other banks’ and retailers’ machines rather than on branches of its own. Its history lists ATM connections with the Bank of Tokyo-Mitsubishi in 2003, UFJ Bank in 2005, Seven Bank in December 2006, Lawson in October 2008, E-net in November 2008 and Aeon Bank in August 2014. In June 2010 it opened a face-to-face counter for home-loan advice, renamed CONSULTING PLAZA in 2017.

Inside Sony’s financial group.

Sony Bank has always sat inside Sony’s financial businesses. In April 2004 Sony Financial Holdings was founded, and the bank became a member of that group alongside Sony Life and Sony Assurance, its history says. Sony Financial Holdings was listed on the First Section of the Tokyo Stock Exchange in October 2007, and the bank became its wholly owned subsidiary in March 2008. The bank moved its head office to Chiyoda-ku in 2009. In 2020 the holding company was delisted in August, and in September Sony made it a wholly owned subsidiary; it now operates as Sony Financial Group.

The products changed with the devices. The bank began mobile banking in June 2006 and opened a smartphone site in August 2011. In January 2016 it launched Sony Bank WALLET, a cash card with a Visa debit function, with its own app from April 2016, and in March 2017 it issued a version in a PlayStation design. A Sony Bank app followed in February 2019, and account opening by smartphone in April 2021. The history also lists a crowdfunding service, Sony Bank GATE, from 2017, and a digital-securities service developed by Mitsui & Co. Digital Asset Management, offered from 2023.

Partnerships widened the range without new branches. The bank began offering credit cards in December 2005, and in the same month started brokering securities through a tie-up with Monex Beans Securities, now Monex Securities. It set up an online securities subsidiary, Sony Bank Securities, in 2007 and sold it to Monex Group in 2012. Later entries in its history include the Club S loyalty programme in 2017, an ANA Mileage Club version of Sony Bank WALLET in 2019, a basic agreement on a business alliance with Chiba Bank in October 2022, and a foreign-currency deposit link with Japan Post Bank in October 2023.

In March 2026, the history adds, Sony Bank WALLET and the bank’s cash cards took on PEANUTS designs, carrying the comic-strip characters onto the card face.

Screens, ATMs and two scripts.

Japan’s internet and retail-group banks present themselves mostly through screens rather than branches. Sony Bank opened in 2001 with a service website, MONEYKit, instead of a branch network, and Rakuten Bank, which began in 2000 as eBANK Corporation, calls itself an internet-only bank. Their pages are organised around everyday tasks: deposits in yen and foreign currencies, card and home loans, investment trusts and, more and more, apps and account opening by smartphone.

Many carry the name of a larger consumer group. Rakuten Bank took its parent’s name in 2010, and Sony Bank belongs to Sony Financial Group. The banks set a Japanese name beside a Latin one — 楽天銀行 with Rakuten Bank, ソニー銀行 with Sony Bank — so the same name has to work in two scripts on cards, apps and statements.

Cash is still part of the picture, and it is reached through other companies’ machines. Rather than building large ATM networks of their own, these banks connect to machines in convenience stores and other banks: Rakuten Bank’s 2010 tie-ups with E-net and Lawson put its cards into FamilyMart, Ministop and Lawson stores, and Sony Bank’s history lists connections with Seven Bank, Lawson, E-net and Aeon Bank. Card faces have become a place for character illustration, as with Sony Bank’s PlayStation and PEANUTS designs.

Behind the consumer pages sits a more formal layer of disclosure sections, press releases and investor documents. This guide sets out what can be checked about each bank — who set it up, who owns it and when its name changed — and marks clearly what rests on the bank’s own word.

A spun-off group and new technology.

In September 2025 Sony separated its financial arm. Insurance Journal, carrying a Bloomberg report dated 29 September 2025, said Sony Financial Group began trading in Tokyo that day after a rare spinoff listing by Sony Group, which was sharpening its focus on entertainment and image sensors; the report called it the first direct listing in Japan in more than two decades. Sony Bank’s own history records the listing of Sony Financial Group on the Prime Market in September 2025, and the bank’s company profile names Sony Financial Group as its sole shareholder.

The bank has also moved into newer technology. Its history lists a web3 entertainment app, Sony Bank CONNECT, in July 2024; a new core banking system in May 2025; a “smartphone ATM” service in September 2025; and a web3 subsidiary, BlockBloom, which began business in October 2025. In September 2026 Sony Bank and Fujitsu said they had applied generative AI at full scale in developing the bank’s core banking system, which runs on Fujitsu’s cloud-based Core Banking xBank. The bank’s history adds an October 2025 business agreement with Bastion Platforms aimed at a US dollar stablecoin business, a February 2026 memorandum of understanding with JPYC on stablecoin services, and conditional approval in July 2026 from the US Office of the Comptroller of the Currency towards setting up a US trust subsidiary.

The bank’s statement says it wants to widen the possibilities of each customer who wants to live in their own way, and to offer a new kind of banking experience.

For a design guide, Sony Bank shows how a consumer-electronics name can carry over into banking, with card faces that borrow from the group’s games and from licensed characters. Compare Sony, the group that set it up, and Rakuten Bank, another Tokyo internet bank tied to a consumer group. For this guide we use a deep navy, a clear blue and a silver grey with a sans, an unofficial interpretation; no product or logo is reproduced.
