Docomo Bank

Docomo Bank (ドコモSMTBネット銀行) is a Japanese online banking brand operated by Sumishin SBI Net Bank, which was rebranded on August 3, 2026, following its acquisition by NTT Docomo. The bank offers a full range of internet banking services, including yen and foreign currency deposits, investment trusts, loans, mortgages, and debit/credit cards. It is known for its fee-free ATM withdrawals and transfers, d-point rewards for Docomo users, and 24/7 security monitoring. The rebranding reflects NTT Docomo's strategy to integrate financial services with its telecommunications and lifestyle platform, aiming to become a 'tech company beyond banking.' The bank was previously listed on the Tokyo Stock Exchange Standard Market but was delisted on September 25, 2025, through a tender offer by NTT Docomo. It continues to serve both Docomo and non-Docomo customers, emphasizing convenience, digital innovation, and customer satisfaction, as evidenced by various awards and high app download numbers.

On August 3, 2026, the bank was rebranded as Docomo SMTB Net Bank, reflecting its new ownership under NTT Docomo.
