Coincheck Group N.V., the Amsterdam-based digital asset services company, has completed a $65.1 million strategic investment from KDDI Corporation, marking a notable tie-up between a crypto platform and one of Japan’s largest telecommunications groups.

Under the deal, KDDI purchased 28,536,516 newly issued ordinary shares at $2.28 per share, giving it a 14.9% ownership stake in Coincheck Group. The transaction follows a share subscription and investment agreement signed on May 12, 2026.

Alongside the investment, Coincheck Group’s Japanese subsidiary, Coincheck, Inc., entered into a business alliance with KDDI aimed at expanding the digital asset market in Japan. The agreement includes mutual customer referral programs, revenue sharing, and referral fees.

The move highlights continued efforts to connect digital asset platforms with large-scale consumer distribution channels, particularly in Japan, where Coincheck already has an established retail presence and is expanding into institutional services and digital asset infrastructure.
