Japan Trustee Services Bank, Ltd. (日本トラスティ・サービス信託銀行株式会社, Nippon Torasuti Sābisu Shintaku Ginkō Kabushiki-gaisha), or JTSB, is a trust bank in Japan.

JTSB is a joint venture between Resona Bank and Sumitomo Mitsui Trust Holdings, and acts as a subcontracted trustee for both banks to hold their customers' assets, which include pension fund and investment trust assets. Its main competitors are The Master Trust Bank of Japan (controlled by Mitsubishi UFJ Financial Group and Nippon Life Insurance) and Trust & Custody Services Bank (controlled by Mizuho Financial Group).

JTSB's SWIFT (ISO 9362) code is JTSBJPJT.

In July 2020 JTSB merged with the Trust & Custody Services Bank to form Custody Bank of Japan.
