Japan’s Monex Group, which bought hacked cryptocurrency exchange Coincheck about a year ago, has announced major management changes.

Coincheck made the news last year for having a whopping $530 million stolen in a cyber attack. Monex Group, reportedly Japan’s third-largest online brokerage firm by customer accounts, had acquired Coincheck for JPY 3.6 billion (USD 32.6 million) to make its foray into the crypto scene.

On March 27, it made public a slew of switches in positions for its executives across its companies, including Coincheck, to take effect as of March 31 and April 1. Most notable is that Monex Group’s current Representative Executive Officer and Company President Oki Matsumoto will become Representative Director and Chairman of Monex Inc, the group’s retail online brokerage, as well as Chairman of Coincheck.

Amongst several other portfolio changes, three Executive Directors of Coincheck will also concurrently serve as Executive Directors of Monex Group to enhance internal cooperation across the group’s companies. Monex Group Chief Investment Officer Koichi Tateno will resign to become Senior Advisor instead, while current Executive Officer Masaki Ueda who looks after the group’s crypto asset business will also become Coincheck’s Managing Director.

Monex Group said that with such changes, it expects to “further revitalize the organization, move our business forward with more flexibility, and realize synergy effects among the group companies”.
