What is Japan Open Chain (JOC)?

Japan Open Chain (JOC) is an Ethereum-compatible Layer 1 public blockchain jointly operated by Japanese companies. It is designed to support a wide range of use cases, including payments, NFTs, and decentralized applications (DApps). The network positions itself as an enterprise-grade blockchain infrastructure, built to serve as the foundation for future financial systems such as stablecoins and real-world assets (RWAs).

The project is developed and managed by Japan Blockchain Foundation Co., Ltd., with core development contributions from G.U. Group and its subsidiary G.U. Technologies. The native token, JOC Coin, serves as the fee token required to use the network. The total supply of JOC is capped at 1,000,000,000 tokens, which have already been issued. An ERC-20 cross-chain token, JOCX, is also live, based on the native JOC Coin.

Since its launch in 2024, Japan Open Chain has moved through several key phases, including an initial exchange offering (IEO) and simultaneous listings on multiple global exchanges. The project continues to evolve, with a long-term roadmap extending toward 2030 that includes performance improvements, post-quantum cryptography, and cross-chain DAO development.

Who created Japan Open Chain?

Japan Open Chain was initiated in 2022 by a group of blockchain technology experts, entrepreneurs, and key figures in the Japanese financial sector. The project is operated and managed by Japan Blockchain Foundation Co., Ltd., which oversees the consortium governing the public blockchain.

Core development and business solutions are provided by G.U. Group, Inc. and its subsidiary G.U. Technologies Inc. G.U. Group is headquartered in Shibuya, Tokyo, and was established in April 2018. Its CEOs are Hidekazu Kondo and Daimei Inaba. Daimei Inaba is also referenced as a co-founder of JOC and speaks publicly about JOC use cases.

The project collaborates with a range of partners and validators. Notable partners include IoTrust, whose CEO Sangsu Baek joined the JOC Development Partner Program, and BitTrade, led by CEO Lei Guan. The whitepaper was published by Japan Blockchain Foundation Co., Ltd., with a version dated November 2024.

How does Japan Open Chain work?

Japan Open Chain operates as an Ethereum-compatible Layer 1 public blockchain. This means developers can use existing Ethereum smart contracts, tools, and programming languages such as Solidity directly on JOC without modification. The network provides RPC endpoints and developer documentation to support deployment.

The blockchain is currently operated by a set of validators, which are organizations that participate in block production and network governance. Initially, the network used a Proof of Authority (PoA) consensus mechanism, where validators are known and trusted entities. The project is transitioning to a Proof of Staked Authority (PoSA) model through the Tokyo Hard Fork. This upgrade is intended to enhance decentralization and security by introducing staking requirements for validators.

The Tokyo Hard Fork testnet migration was completed on September 7, 2026, and the network began operating under the new PoSA environment. The team is monitoring network stability and validator operations on the testnet before proceeding with the Mainnet migration. The network is expected to expand to 21 validators in the future.

What makes Japan Open Chain unique and valuable?

Japan Open Chain distinguishes itself through its compliance-focused approach and its consortium of reputable Japanese companies. The project is designed to comply with Japanese laws and regulations, making it suitable for enterprise and institutional use cases. This regulatory alignment is a key differentiator in the Japanese market.

The network is operated by a diverse set of validators, including major corporations such as Dentsu Inc., NTT Communications, TIS Inc., pixiv Inc., and Kyoto University of the Arts. This participation from well-known entities provides a high degree of reliability and security. The involvement of companies from both traditional industries and Web3 sectors supports the network's credibility.

Another unique aspect is the project's focus on real-world financial infrastructure. Japan Open Chain is actively pursuing bank-led stablecoin projects and the digitization of assets. The planned issuance of EJPY, a Japanese yen-backed stablecoin, under a trust-type scheme represents a significant step toward evolving the blockchain into a practical payment infrastructure. The project also aims to provide instant transfers with fees under 1 yen, making it accessible for everyday use.

What is JOC used for?

JOC Coin is the native token of the Japan Open Chain network and serves as the primary utility token. Its main use is as a fee token, which is required to pay for transaction fees and smart contract execution on the network. Users need JOC to interact with the blockchain, whether for simple transfers or for deploying and using DApps.

Beyond transaction fees, JOC is used within the ecosystem for various services. These include NFT marketplaces, decentralized exchanges (DEXs), and lending programs. The JOC Lending Program, operated by G.U. Group's Singapore subsidiary, allows users to participate in lending activities. The token also facilitates participation in community quests and reward programs.

The cross-chain JOCX token extends the utility of JOC by enabling interoperability with other blockchain networks. This allows JOC-based assets to be used in a broader range of decentralized finance (DeFi) applications. Additionally, JOC is used in stablecoin projects and other financial initiatives being built on the network, such as the EJPY stablecoin and the DEC (Data Economy Coin) project.

How Is the Japan Open Chain ecosystem developing?

The Japan Open Chain ecosystem is expanding through a combination of product development, partnerships, and community initiatives. The project offers several products and services, including Lunascape, G.U.Wallet, and the JOC Dashboard, which allows users to manage assets and NFTs on the network. These tools are designed to make the platform accessible to both developers and end-users.

Strategic partnerships are a key part of ecosystem growth. IoTrust joined the JOC Development Partner Program to promote services on the blockchain. The DEC (Data Economy Coin) project is preparing for issuance on Japan Open Chain and potential listing on Zaif, with a memorandum of understanding signed between the parties. The EJPY stablecoin project, announced by the Japan Blockchain Foundation, aims to create a yen-backed stablecoin for B2B payments and digital asset use cases.

Community engagement is also active. The project has launched initiatives such as the Lunascape × TaskOn Quest, which offers exclusive NFTs and USDT rewards to participants. The JOC Earn Program provides opportunities for users to earn annualized yields with instant payouts in stablecoins. The project maintains a presence on social media platforms including X (Twitter), Discord, LinkedIn, and through podcasts, providing information on Web3 business and project updates.

How to mine Japan Open Chain?

Japan Open Chain does not use a traditional mining mechanism like Proof of Work. Instead, it relies on a validator-based consensus system. Initially, the network used Proof of Authority (PoA), where a set of approved validators produced blocks. With the Tokyo Hard Fork, the network is transitioning to Proof of Staked Authority (PoSA), which introduces staking elements to the validator selection process.

To participate in securing the network, users can become validators or delegate stake to existing validators. Validators are required to stake tokens and meet certain criteria to be selected for block production. The project currently operates with a set of validators and plans to expand to 21 validators in the future. Interested parties can contact the project to inquire about becoming a validator or business partner.

For regular users, there is no mining process. Instead, users can acquire JOC through supported exchanges or participate in staking and lending programs to earn rewards. The JOC Lending Program and Earn Program provide avenues for token holders to generate yield on their holdings. These programs are managed by G.U. Group and its subsidiaries, with allocated funds to support liquidity and attractive lending opportunities.

How to keep your JOC Coin safe?

Keeping your JOC Coin safe requires following standard cryptocurrency security practices. Since JOC is an ERC-20 compatible token on an Ethereum-compatible blockchain, it can be stored in wallets that support Ethereum-based assets. Hardware wallets, such as those from Ledger or Trezor, provide a high level of security by keeping private keys offline. Software wallets, including G.U.Wallet, offer convenience for everyday use.

When using exchanges to buy or trade JOC, it is important to enable two-factor authentication (2FA) and use strong, unique passwords. For long-term storage, it is advisable to move tokens to a personal wallet where you control the private keys. Never share your private keys or seed phrase with anyone. Be cautious of phishing attempts and only use official links provided by the project.

Users should also be aware of the regulatory environment. Residents of Japan can only use BitTrade among the listed exchanges, while other exchanges are available to residents of other countries. It is important to comply with the laws and regulations of your country of residence. The project and its partners assume no responsibility for legal disputes, tax issues, or regulatory inquiries arising from the use of exchanges. Always conduct your own research and consider consulting a professional advisor before making investment decisions.
