Overview
iChain is a blockchain-based insurance SaaS provider serving carriers and individual policyholders in Japan. Incorporated in April 2016, the company addresses inefficiencies in Japan's insurance market by digitizing policy contract management and claims processing for both enterprise and consumer segments.
The company operates two core products: iChain Base, a SaaS contract management platform for insurance carriers that stores policy data on a distributed ledger, and Uchi no Hoken (iChain Insurance Wallet), a mobile application for policyholders to centrally manage policies from multiple insurers. Both products integrate through APIs with existing Japanese insurance systems.
By March 2025, the consumer wallet application had surpassed 100,000 registered users. iChain holds Privacy Mark certification (November 2024) and participates in the Japan FinTech Association and Japan Micro Insurance Association. The company has received recognition through NTT Data's Innovation Contest and Plug and Play Japan.
