Kuhito Inc. (Headquarters: Yokohama, Kanagawa; CEO: Yu Kagaya) was founded on March 5, 2026, with a mission to implement and popularize blockchain technology as a social infrastructure, specifically focusing on Midnight and Cardano in Japan's corporate, administrative, and public sectors. Midnight is a privacy-specialized blockchain being developed by IOG (Input Output Group), the entity leading Cardano's R&D. As a 4th-generation blockchain, it supports programmable privacy technology and is expected to have a wide range of use cases.
### Background of Establishment
While blockchain technology offers great potential as social infrastructure due to its tamper-resistance, transparency, and automated execution via smart contracts, adoption in Japan has remained limited. This is due to a prevailing image of 'crypto speculation' and significant hurdles related to regulatory compliance and privacy protection. Conventional public blockchains, while ensuring transparency, expose transaction data to the entire network. This structure makes it difficult to balance with privacy needs for handling personal information, contracts, and trade secrets in corporate and governmental operations.
Midnight addresses these challenges by incorporating programmable privacy and 'selective disclosure.' It allows users to prove facts without revealing confidential data itself. Kuhito Inc. was founded to build a practical infrastructure using such technology, moving blockchain beyond speculation into a useful tool for society.
### Business Activities
1. **Product Development using Midnight/Cardano**: Leveraging technology that ensures verifiability without revealing sensitive data. The company is currently developing an MVP for the Japanese market.
2. **Developer Education and Support**: Training domestic developers in Midnight's 'Compact' language (TypeScript-based DSL) and Cardano's Plutus/Aiken, bridging Web2 engineers to the Web3 space.
3. **Consulting for Enterprises and Government**: Providing end-to-end support from technical selection to system design and operation.
4. **Validator Operation Support**: Offering technical assistance based on expertise gained from the SPO JAPAN GUILD.
5. **Cardano Ecosystem Expansion in Japan**: Supporting the commercialization and popularization of the Cardano ecosystem through local community collaboration.
