Creating the standard for a new generation

When I decided to establish Retty in 2010, I made a decision. “We’ve got only once to live. I want to build a new future and make people around the world happy.”

At Retty, we have attracted many excellent people who share the same desire to “make people around the world happy”, and we continue to grow each day.

However, the future we are aiming for is still a long way off, and we are still in the middle of the journey. In order to provide new value to more than one billion people around the world, we must expand the service that Retty offers even farther.

Food is at the heart of everyday life, and I think dining out is an area in which Japan leads the world. Creating a new future in the food space and bringing happiness to people around the world—these are what you can expect from Retty. We appreciate your continued support, now and into the future.
