About Peace and Passion

Peace and Passion, affectionately known as ✌️ Peace!, is a social startup based in Japan.

We started with seven members and two of us remained. For ten years, we've run with our own money as unpaid volunteers, financial aid from family and donations.

We have meticulously crafted both the theory and the system that will serve as a social foundation. It has finally reached operational status.

At its heart, what Peace creates is not just technology or tools, but communities that foster regional development and creates a new era. We work not for profit, but for realizing a new era that EVERYONE can keep peace of mind and passion.

We are eager to collaborate with more companies, organizations, and individuals. Please do not hesitate to contact us.

We're thankful to donors, volunteers, our families, friends, and institutes who've helped us.

The hardest thing for me is reading stories about small children being abused by their parents on the newspaper in Japan.

Children were not given food, or boiling water was poured on them. Parents are hitting their children.

I want to make the world's parents happy first for children. I want everyone to be able to live with peace of mind and passion. I don't have much time left. I'm running at full speed.

We pursue our art. When in doubt, we follow our mission and conscience.

Our workday begins at 8:30 with friendly greetings for everyone. The atmosphere is akin to that of a university laboratory. We have a scheduled exercise break and enjoy our lunch in the beautiful university surroundings, often followed by a leisurely walk. We also have nap breaks. At the end of the day, we leave the office at 17:59 and strive to be in bed before 22:30.

We are a big family and learning animals; we read newspapers and books everyday. In summer we climb mountains and enjoy body-boards at the beach. No smartphone or caffeine addicts here.
