What G.U. Group does
G.U. Group Co., Ltd. is a Tokyo-based, privately-held blockchain infrastructure and web3 product company founded in April 2018 (originally as G.U. Labs, renamed December 2023). It is led by Co-CEOs Hidekazu Kondo and Daimei Inaba and operates through wholly-owned subsidiaries including Japan Blockchain Foundation Co., Ltd. (which manages the Japan Open Chain consortium), G.U. Technologies Inc. (stablecoin and NFT solutions), and Singapore-based G.U. Technologies Global PTE. LTD. (international operations). The group raised ¥420 million (~$2.9M) in December 2023 led by B Dash Ventures.
The company's core product is Japan Open Chain (JOC), an Ethereum-compatible Layer 1 public blockchain using Proof-of-Authority consensus, operated by a consortium of 14 (expanding to 21) Japanese corporate validators including Sony Group startup CORGEAR, Dentsu, NTT Communications, TIS, pixiv, Minna Bank, SBINFT, TV Asahi's extra mile, Hatena, CAC, Cyberlinks, Kudasai, Nethermind, Pacific Meta, and insprout. JOC is purpose-built for Japanese regulatory compliance under the revised Payment Services Act, enabling trust-bank-issued stablecoins and enterprise-grade NFT issuance at sub-1-yen per transaction with deterministic finality. The product stack extends to G.U. Coin Studio (stablecoin issuance system for banks), G.U. Blockchain Cloud (BaaS for building Ethereum-compatible consortium chains in three steps), G.U. Token Studio (no-code NFT marketplace tool), and the consumer-facing Lunascape web browser (20M+ cumulative users over 20+ years) with integrated G.U. Wallet for web3 access. Cross-chain interoperability is enabled through LayerZero and Fujitsu ConnectionChain integrations, with SubQuery providing data indexing.
G.U. Group generates revenue primarily through enterprise SaaS/licensing (G.U. Coin Studio, G.U. Blockchain Cloud), web3 consulting services to Japanese corporations, financial institutions, and local governments (clients include NTT Communications, Tokyo Kiraboshi Financial Group, Minna Bank, COGEAR/Sony, Shikoku Bank, KEIT, insprout), usage-based transaction fees on Japan Open Chain (with JOC COIN as the gas/fee token), and token sales/IEO proceeds (domestic IEO on BitTrade, second listing on Zaif in February 2026). The go-to-market combines direct enterprise sales with co-selling through technology partners (Bunzz, Fujitsu, LayerZero, double jump.tokyo's N Suite), event-driven ecosystem building (FIN/SUM, TOKEN2049, WebX, Fintech Surge), and consumer distribution via the Lunascape browser. The customer base spans financial institutions, large enterprises, local governments (e.g., Kaga City e-Kaga Citizen Certificate NFT), and consumer/SMB end users, with most enterprise relationships still in POC or pilot stage as of early 2026.

Revenue model
- Software Licensing / SaaS (G.U. Coin Studio, G.U. Blockchain Cloud): G.U.Group derives revenue from licensing its proprietary blockchain infrastructure and web3 software products to enterprise clients. G.U. Coin Studio is sold to financial institutions for stablecoin issuance; G.U. Blockchain Cloud is a cloud service for businesses to build their own blockchains. Revenue is generated through licensing fees, platform fees, or usage-based pricing for these enterprise SaaS products.
- Transaction Fees / Blockchain Network Fees (Japan Open Chain): Japan Open Chain generates fees for on-chain transactions including NFT issuance (under 1 yen per transaction), smart contract execution, and other blockchain actions. The JOC token functions as the fee token (Gas equivalent) compensating validators. Post-IEO, token transaction fees and potential staking rewards contribute to network economics.
- Web3 Consulting Services (G.U. web3 Consulting): G.U.Technologies provides web3 business consulting services for companies and local governments considering blockchain/NFT/stablecoin projects. Services include project planning, business plan advisory, and system requirements definition. Clients include NTT Communications, Tokyo Kiraboshi Financial Group, Minna Bank, COGEA, insprout, KEIT, Shikoku Bank, and others.
- Token Sales / IEO: G.U.Group conducted token sales targeted at overseas investors as part of its 420 million yen fundraising round. Japan Open Chain's native token (JOC COIN) underwent domestic IEO on BitTrade (first Japan listing) and subsequent listing on Zaif (February 2026). Token sale proceeds represent a fundraising mechanism rather than a recurring revenue stream.

G.U. Group competitors and assessment
Company assessmentDirect peers
- HashPort: Japanese blockchain consulting and infrastructure company focused on enterprise tokenization, NFT platforms, and consortium chain services. Competes with G.U. Group in the Japanese enterprise blockchain consulting and consortium chain market, particularly for tokenization projects for financial institutions and government entities.
- double jump.tokyo: Tokyo-based blockchain infrastructure company specializing in NFT and game-focused chains, with the N Suite enterprise wallet integrated with Japan Open Chain. Direct peer in Japanese blockchain infrastructure with overlapping enterprise wallet and NFT tooling offerings, also a JOC Development Partner.
- Astar Network (Startale Labs): Japan-developed Layer 1 blockchain with strong Japanese enterprise and government adoption including partnerships with NTT Docomo and Toyota. Competes with Japan Open Chain for Japanese enterprise web3 workloads, particularly in NFT and DeFi use cases, though Astar is more decentralized (NPoS) versus JOC's PoA.
- Progmat (Mitsubishi UFJ Financial Group): Operated by MUFG's Progmat Inc., Progmat is a competing Japanese stablecoin issuance and tokenization platform targeting bank-issued stablecoins under Japan's revised Payment Services Act. Both G.U. Group and Progmat serve the same primary buyer segment (Japanese banks and trust banks) with tokenization and stablecoin issuance infrastructure, making them the most direct head-to-head competitors in Japan's regulated stablecoin market.
Others
- JBA (Japan Blockchain Association): Japan's leading blockchain industry association including major exchanges, banks, and blockchain companies. Not a direct competitor but an ecosystem participant whose member activities and policy advocacy shape the Japanese regulatory environment in which G.U. Group operates.
Broad incumbents
- Polygon Labs: Global Ethereum Layer 2 scaling solution with deep liquidity, mature developer ecosystem, and significant Japanese enterprise partnerships. Competes with JOC for global enterprise tokenization workloads, particularly in NFT and DeFi where Polygon's deeper liquidity and tooling may be preferred over a permissioned consortium chain.
- ConsenSys: Ethereum infrastructure company behind MetaMask, Infura, and Linea (L2). Competes with G.U. Group's enterprise blockchain offerings through Linea and enterprise Ethereum tooling, particularly for Japanese banks and corporations exploring public-chain-based stablecoin and tokenization use cases.
- SBI Holdings (SBI R3 Japan, SBINFT): Major Japanese financial conglomerate with extensive crypto, NFT (SBINFT is a JOC validator), and blockchain operations. Operates crypto exchanges, custody services, and is developing proprietary tokenization infrastructure, overlapping with G.U. Group across multiple segments.
Regional players
- Oasys: Japan-focused gaming-optimized Layer 1 blockchain backed by major Japanese gaming companies (Bandai Namco, Square Enix, Sega). Competes with JOC for Japanese IP and entertainment web3 use cases including NFT and tokenized gaming assets, though Oasys's validator set and ecosystem focus more on gaming than financial services.
Emerging players
- Ava Labs (Avalanche): Avalanche's subnet architecture enables permissioned, compliant blockchain deployments similar to JOC's positioning, with several Japanese banks (including MUFG's GoSoroban) exploring Avalanche subnets for stablecoin and tokenization. Competes for the same regulated enterprise use cases in the Japanese market.
