Hi, I’m Hiro.

After encountering my first Macintosh computer at home when I was a kid, I learned the joy of creating through a computer. Right after that, I was strongly influenced by a tv program on Marc Andreessen’s Netscape-driven internet revolution.

As a middle-schooler, I visited the US for the first time and encountered the phenomenon that would later be termed the dot-com bubble. This was when I decided to pursue a career in the tech industry.

Back in Japan, I devoted myself to software development. After tasting initial success by creating a mobile website, I founded my first startup at the age of nineteen. Since then, I have been involved in numerous internet-based startups in fields including mobile applications, cloud hosting, IoT semiconductors, and have founded companies in Japan, Singapore, Taiwan, and the US.

I was inspired by the emergence of Bitcoin and its aim to create a decentralized society, and since then, I have chosen to focus my work on Cryptocurrency and Blockchain. In 2013, I founded the website BitBiteCoin.com to provide news about Bitcoin. In 2015, I co-founded a company called SIVIRA to research and develop Blockchain in order to establish a new economic model for the next generation. Furthermore, since 2017, I’m running a bunch of startups under a decentralized organization Hulor to make a sustainable society with emerging disruptive technologies like Blockchain.

On a different note, I am also the author of popular blog articles about the Evangelion series.

6歳の時、自宅にあった Macintosh に出会い、コンピュターでものを作る喜びを経験する。11歳の時、テレビで見た Netscape と、Marc Andreessen が起こした革命に強い衝撃を受ける。そして、中学生時代。アメリカ西海岸を訪れ、後にドットコムバブルと呼ばれる現象を目の当たりにする。その時、テクノロジー業界での起業という生き方を決意する。

帰国後、ソフトウェアの開発に没頭。学生時代に作成した i-mode サイトのヒットで感触を掴み、19歳で起業。以降、モバイルアプリ、クラウドホスティング、IoT 半導体等、インターネット関連の複数のスタートアップに携わり、日本、シンガポール、台湾、アメリカで起業をする。

ビットコインの登場以降は、非中央集権社会を実現するそのテクノロジーに感動を覚え、仮想通貨及びブロックチェーンの事業に力を注ぎ始める。2013年にはビットコイン関連ニュースサイト BitBiteCoin.com を立ち上げ、2015年には次世代の経済モデル確立を目指すブロックチェーン研究開発企業 SIVIRA を共同創業。そして2017年以降は、ブロックチェーン等の破壊的イノベーションによって、持続可能な社会の実現を目指す分散型企業群、Hulor を運営している。
