“What I do not want to do is create a good world not do it.”
It is a vision of RADIOBOOK, mission.

Yugo Itagaki Yugo Itagaki


“I have not done is that you do not want to do” (commonly known as “spear Yara”)
This is the title of my book, it is my belief.

In my case, paperwork is something I don't like to do. So I leave it to those who are good at it.
On the other hand, I am very good at creating brands and business strategies, which is what I want to do. Sometimes I help someone else to do it.
What someone is not good at is what someone else likes, so if we could exchange these things, everyone would be happy. That's what I'm really serious about.

We're going to get rid of all the things in the world that we don't want to do.

That is our corporate mission.

Based on this philosophy, we are developing four different businesses
Mobile SOS (smart on-demand service)
Concierge service for high class mobile devices
Branding services
Community services
Sundae bar
Martial arts business

Among other things, a partnership agreement has been signed with Ferrari from 2020, which will see supercars with the Radiobook logo driving on the Formula 1 circuit.

In this way, Radiobook hopes to become the world's largest “Yari-yara” through its various businesses, the mainstay of which is the smartphone-related business.

If this message resonates with you, please check out our online salon, “Yari-yara Town”, where we show the entire process of various Radiobook projects. You can also get advice from me and other core members of the team, so please have a look. We're also always happy to discuss business partnerships with great companies like Ferrari.

Shall we start our conversation there as a part of our community?

Looking forward to seeing you.
