Word from the CEO

Hello, I’m Tetsuo Omorai, the CEO of No.1 Solutions Inc.
Ever since we set our vision of achieving world peace through technology, we have been thinking about what we can do as a business.

The answer we came up with is that we want to be a company that solves social issues through technology and change society for the better.
Technology has evolved greatly in the past 10 years.
Not only the IT industry, but all industries will continue to renovate.

In these turbulent times, I would like to provide solutions that contribute to the world by combining technology with the good qualities of Japan, rather than being at the mercy of technology.

One of the technologies is called blockchain.
I would like to use the blockchain technology we have cultivated as a foundation to provide mechanisms that will revolutionize society in the areas of finance, traceability, and smart contracts.
Thank you for your continued support of No.1 Solutions Inc.
