On the 12th, domestic cryptocurrency exchange OKJ announced the establishment of a strategic partnership with Mobcast Holdings, a company listed on the Tokyo Stock Exchange Growth Market. The partnership centers on developing treasury operations focused on Solana (SOL).
Since 2025, more companies around the world have been adopting Digital Asset Treasury (DAT) strategies—integrating digital assets such as Bitcoin (BTC) into their financial management plans, reflecting changes in global affairs and financial markets. Mobcast Holdings began implementing a Solana-focused treasury strategy last month and has accumulated a total of 9,070 SOL as of November 7.
Looking ahead, the company aims to become one of Japan’s top corporate holders of Solana by the end of 2025, accelerating its acquisition pace. Furthermore, it has presented a concrete vision for a new “Social Impact Passport (SIP)” initiative—an innovative circular model that balances corporate growth with social value creation. Through its Solana treasury operations, the company seeks to establish a next-generation social contribution model.
According to the announcement, OKJ will provide comprehensive support for Mobcast Holdings’ initiatives. Moving forward, OKJ will assist the company in building its Solana acquisition, management, and operation framework, while also contributing proactively to projects that create high social value.
