The New Global Standard from Japan

Japan Smart Chain (JSC) is an Ethereum Equivalent Japan-sovereign public-permissioned blockchain, validated entirely onshore by domestic industry leaders. Engineered as a “compliance-first” Layer 1, embedding blacklist enforcement - making it a trusted infrastructure for regulated digital-asset services without sacrificing usability.

Mission

Our mission is to streamline Japan’s digital ecosystem by building a sovereign web3 infrastructure that addresses real customer and business pain points in the current application layers -  delivering solutions that are quick, cost-efficient, trustworthy, and scalable

Our Guiding Principles

  • Sovereignty
    • Validated onshore in Japan by domestic industry leaders.

    • Within the control of Japan.

    • Beyond the influence of outside regulatory forces.

  • Security
    • Software upgrades in lockstep with Ethereum.

    • Leveraging Japan's top engineering talent.

    • Technical experience with enterprise grade blockchain and financial systems.

  • Safety
    • Governance and blockchain level consumer protections via eKYC/DID.

    • AML and anti-social compliance policies embedded at the infrastructure layer.

    • Customers of regulated on-chain services can safely interact with others.

  • Scalability
    • Compatible with major L2 ecosystems from Mainnet launch.

    • Advancements made to either JSC or Ethereum are mutually beneficial, reducing engineering redundancy.

    • With nodes located in closer proximity, JSC L1 provides higher transaction throughput and speed than Ethereum Mainnet.

Introducing the Mizuhiki Protocol

Mizuhiki Suite is a modular trust & compliance suite built on top of Japan Smart Chain (JSC).

It provides everything required to anchor verified identity, regulatory compliance, and risk management directly on-chain, so businesses can launch and manage regulated digital services without relying on fragmented off-chain processes. Designed for flexibility across industries, enterprise needs and use cases, with future modules easily integrable.
