Business overview

Development and social implementation of blockchain platform technologies

Business concept for addressing social issues

We are a leading company advancing social implementation of blockchain to make it the social platform for the Web3 era. 
We have developed enterprise public blockchain Tapyrus, offering TapyrusAPI through a subscription service to address use cases such as for traceability and sustainability.

Solving issues, mission/products and services for solving the issues

By rolling out blockchain platform Tapyrus that offers (l) both governance and openness, (2) scalability and (3) collaborations between chains, which were factors blocking blockchains from getting implemented in society, we can bring a circular economy in four domains, which are traceability, sustainability, trusted services and digital assets.

Market overview/overview of the market entering (macro)

Since our founding in the City of Iizuka, Fukuoka Prefecture, we have conducted research on public blockchains and developed the public chain for corporations, named “Tapyrus”. In various fields such as sustainability and traceability, we have a track record of introducing this blockchain to local governments such as Fukuoka Prefecture, Kumamoto Prefecture, and the City of Iizuka, as well as to companies.
In the field of digital assets (local currencies, tokens), we provide technologies to major railway companies, and our service currently has over 1 million users. We are the core company of “the Blockchain City Vision” advocated by the City of Iizuka.
