About Us

We are sports nerds and fanatics...


Sports have had a tremendous impact on our lives and shaping our personalities.

Have brought us joy, frustrations and the realization that dreams can come true.

Developed friendships and comradery.

Now it's time for us to give back to sports...

The human being that shape the sports world have taught us that there are no limits.

In Japan there are two general ways to enjoy sports = Playing and Supporting

We believe that the fun opportunities are larger and virtually endless.


In the US sports are focused on increasing the entertainment and engagement aspects.

We believe that we can change and expand the definition of "playing" sports in Japan.

The value of sports participation will increase.

"Play Sports"

People who are not normally interested in sports should be intrigued by its collaborative powers.

What will sports teach us when more and more people become engaged?

We greatly look forward to the future of sports and hope you can all join our journey
