Binance Japan has named Cega co‑founder Arisa Toyosaki as its new general manager and representative director, effective July 1. With the move, current leader Takeshi Chino will step aside as CEO and assume the roles of honorary chairman and director, while remaining on the board.
Binance Japan says in its June 30 announcement that Toyosaki will become general manager on July 1. She steps in after four years in which Chino oversaw the unit’s launch and early growth.
The company says Chino will retire from his current position and take a new role as honorary chairman and director. That role lets him keep providing strategic advice and support a smooth handover. Therefore, the leadership shift aims to maintain continuity at the exchange while bringing in a new operational head.
Binance Japan calls Toyosaki an executive with “extensive experience in fintech and technology.” It says she has a strong record of guiding businesses through “innovation, growth, and transformation.”
As general manager, she will lead the unit’s “next growth phase” and expand access to digital assets. She will also strengthen partnerships and improve user experience in what the company calls “one of the world’s most important digital asset markets.”
Who Is Arisa Toyosaki, Binance Japan’s New General Manager?
Toyosaki brings a mix of traditional finance, big tech, and crypto to the post. She studied computer science and economics at Northwestern University in the US before working as a futures trader at UBS Securities in Hong Kong, then at Google Japan on search services and augmented reality projects.
Arisa Toyosaki left Google to co‑found DeFi protocol Cega in 2022 and built on‑chain structured investment products there. She sold the Cega project in 2025.
Toyosaki also appears on the Forbes “30 Under 30” list and advises the Japan Blockchain Association. Those roles give her recognition in both startup and policy circles. With this background, Binance Japan says she is well placed to guide the exchange through Japan’s fast‑evolving digital asset market.
Chino, who has served as representative director and helped build Binance Japan’s presence since its launch, will not be leaving the company outright. Instead, he will continue as honorary chairman and director, remaining on the board to offer high‑level input as Toyosaki runs day‑to‑day operations. Consequently, Binance Japan will keep one familiar face at the top while giving Toyosaki room to lead.
