Overview

The Japan Blockchain Association (JBA), a general incorporated association, is one of the most veteran industry bodies in Japan’s crypto-asset industry. **Its predecessor was the “Japan Authority of Digital Assets (JADA),” established 2014-09 **, which was **renamed to its current name in 2016-04 ** and reorganized as an association overseeing blockchain technology in general. Members include VASPs, blockchain-infrastructure operators, universities, and research institutions. The exchange committee merged with JCBA in 2018-04 to establish JVCEA. Since then, JBA has shifted its focus to technology, research, education, and international coordination, continuing to operate as a blockchain-technology body.

History

• 2016-04 — Renamed the “Japan Blockchain Association (JBA).” Reorganized into an association overseeing blockchain technology in general
• 2017-04 — Following enforcement of the amended Payment Services Act (the virtual-currency exchange registration regime), the exchange committee strengthened its self-regulatory function
• 2018-04 — JBA exchange committee + JCBA → JVCEA was established through a merger (an FSA-accredited self-regulatory association)
• **From 2018 ** — JBA strengthened its character as a technology/research body, while a three-way division of roles became established: JCBA as the industry body, and JVCEA as the accredited self-regulatory organization
