gumi Cryptos Capital is the blockchain and Web3 investment arm of gumi Inc., a publicly listed Japanese mobile game developer (Tokyo Stock Exchange: 3903). The fund was established around 2018 as gumi Inc. moved to position itself at the intersection of gaming and decentralized technology. With a home base in Japan and operational ties to San Francisco, gumi Cryptos targets early-stage and growth-stage projects in blockchain gaming, decentralized finance, NFT infrastructure, and Web3 protocols.
The fund draws on gumi Inc.'s deep background in mobile gaming – a sector that gave it early conviction in play-to-earn mechanics, digital asset ownership, and token-based economies long before those concepts became mainstream. That industry context shapes the portfolio: gumi Cryptos consistently backs projects where gaming, community, and on-chain incentives intersect. The fund operates with a global mandate while maintaining strong ties to the Asia-Pacific region, where gaming adoption and crypto usage rates are among the highest in the world.
Notable investments
- Sky Mavis (Axie Infinity) – one of the defining play-to-earn games; gumi Cryptos participated in early funding rounds before Axie became a global phenomenon in 2021.
- The Sandbox – a voxel-based metaverse platform built on Ethereum; gumi's gaming DNA made this a natural fit.
- Yield Guild Games (YGG) – the pioneering play-to-earn guild and scholarship network based in the Philippines.
- Near Protocol – a layer-1 blockchain designed for developer accessibility and scalability.
- StarkWare – an Ethereum layer-2 scaling company using zero-knowledge proofs; a significant infrastructure bet.
- Immutable X – a layer-2 platform for NFT trading built on StarkEx technology.
- Sorare – a fantasy football platform using licensed NFT player cards, backed by major football clubs globally.

Team
Miko Matsumura is the most publicly identified General Partner of gumi Cryptos Capital. He is a veteran of the early cryptocurrency investment scene, known for backing Ethereum in its pre-sale in 2014, and has been active in Silicon Valley tech circles for decades before moving into dedicated crypto venture work. He regularly speaks at industry conferences and has been quoted extensively in crypto media on topics ranging from DeFi to gaming tokens. Public information about other named partners or the full team structure is limited beyond Matsumura's prominent role.
Hironao Kunimitsu, the founder and CEO of the parent company gumi Inc., has been a vocal proponent of blockchain gaming since at least 2018, lending the fund institutional credibility within Japan's corporate venture landscape. However, his direct operational involvement in the fund's investment decisions is not clearly documented in public sources.
Recent activity
In 2024 and into 2025, gumi Cryptos maintained focus on Web3 gaming infrastructure and layer-2 scaling solutions as on-chain gaming moved from hype-cycle peaks toward more sustainable user metrics. The broader gaming token sector experienced significant valuation corrections after 2021-2022 peaks – a headwind for any fund concentrated in that vertical. Specific new deals announced in 2024-2025 are not well documented in public sources at this time.
gumi Cryptos occupies a distinct niche: a corporate-backed Asian fund with genuine gaming sector expertise and a credible track record of early bets on infrastructure that matured into major protocols. The concentration in blockchain gaming carries cyclical risk – the sector has underperformed broader crypto markets since 2022 – but the fund's early entry points in several marquee projects likely preserve strong paper returns. As on-chain gaming infrastructure matures and mobile-first markets in Southeast Asia deepen their crypto engagement, gumi Cryptos is structurally positioned to continue sourcing deal flow that Western generalist funds may miss.
