Deposit Accounts Has Surpassed 9 Million

SBI Sumishin Net Bank, Ltd. (Head Office: Minato-ku, Tokyo; President & CEO: Noriaki Maruyama) today announced that the number of its deposit accounts (*1) has exceeded 9 million.

Trend in Deposit Accounts

Since commencing operations in September 2007, the Bank has leveraged cutting-edge technologies to deliver a fully digital banking experience. Through its mobile app—designed to provide convenience, security, and an enhanced user interface and user experience (UI/UX)—customers can complete a full range of banking services, including deposits, payments, and loans, entirely online.

Building on the technology and financial expertise cultivated through its innovative initiatives since inception, the Bank has also expanded its Banking-as-a-Service (BaaS) business. By forming alliances with partners across various industries, enabling it to serve a diverse and growing customer base.

On October 1, 2025, the Bank became a consolidated subsidiary of NTT DOCOMO, INC. (Head Office: Chiyoda-ku, Tokyo; President & CEO: Yoshiaki Maeda) and established a joint management structure with Sumitomo Mitsui Trust Bank, Limited (Head Office: Chiyoda‑ku, Tokyo; President: Kazuya Oyama). Following this transition, the Bank rebranded the services it directly provides to individual and corporate customers under the new service brand “d NEOBANK.” By combining DOCOMO’s extensive membership base and multi‑channel capabilities with Sumitomo Mitsui Trust Bank’s advanced financial expertise, the Bank aims to create new value and further enhance the convenience of its service offerings.

Looking ahead, the Bank will soon begin beta testing of “NEOBANK ai,” a next-generation generative UI that leverages generative AI to deliver a more intuitive and personalized financial experience tailored to each customer’s usage patterns and needs.

These initiatives have been well received by customers, contributing to the achievement of 9 million deposit accounts. The Bank extends its sincere appreciation to all customers for their continued support.
