2019 – 2023: Mottainai Kitchen

At the invitation of producer Kenji Sekine/United People, David Groß traveled to Japan for the first time in 2017. The country is one of the biggest food wasters in the world. At the same time, respect for food is deeply rooted in traditional culture. This manifests itself in the fascinating concept of Mottainai, which is a call to sustainable living.

In the summer of 2019, the filming of Mottainai Kitchen took place in Japan.

The documentary premiered in Tokyo in August 2020 and has since been shown in over 80 cinemas across Japan. Mottainai Kitchen is also screening at international film festivals, most recently in the U.S. and South Korea.

Triggered by the movie, an active Mottainai Kitchen movement has sprung up in Japan. Cooking events of the same name are taking place, and the film is also being used in education, universities and schools.
