The company provides the No.1 e-book intermediary service in Japan with a market share of over 2,200 publishers and over 150 e-bookstores. In order to widely distribute digital content such as books and comics domestically and internationally, we have mainly developed B-to-B e-book intermediary systems that register digital content received from publishers and distribute it to e-bookstores. The e-book market in Japan, mainly comics, will reach approximately 350 billion yen in 2019, and it is a market with great potential that continues to grow.

Our e-book intermediary system continues to be designed and developed based on the early e-book distribution business, and in order to support the even greater growth of the e-book market in the future, it will be essential to update the system to be able to withstand this growth. In order to contribute to the further development of the e-book market in the future, it has decided to revamp its e-book distribution system.

To accelerate this project, we are looking for engineers to join our development team.

    About the Product "F"

     

    "F" is an NFT marketplace provided by us, primarily focusing on electronic book distribution. Utilizing blockchain technology as the foundation for NFTs (non-fungible tokens), it offers a service that allows users to acquire, buy, sell, and gift digital content, as well as view exclusive content within the app, providing a broad range of enjoyment for users.

    One of the unique features of "F" is the "NFT Digital Benefits." This initiative attaches digital content to printed publications circulated in bookstores across the country, offering readers a new reading experience. It contributes to increasing the value-added to publications as well as boosting sales (currently adopted by over 2.4 million publications).

    From a technical perspective, we develop and operate everything from the marketplace mechanism to the implementation of smart contracts, and the integration of on-chain and off-chain. In addition to this blockchain technology (web3), we also value the system design and marketing concepts of what is referred to as web2, aiming to build a service that users can enjoy and use comfortably.

    We aims to revitalize the publishing and content industry, including printed books, by providing a system that benefits all stakeholders such as authors, publishers, bookstores, and users. Going forward, we plan to strengthen our approach not only in the publishing industry but across all industries, with the aim of expanding our business.
