Learn About SDGs Through Exhibits

We will introduce the world’s only initiative by TOMUSHI Co., Ltd. — 'the mechanism by which beetles decompose waste' — and display SDGs panels to educate visitors about global environmental issues. This is also recommended for children’s summer vacation independent research projects.

Additionally, decorations in the interactive experience area utilize repurposed oak wood from trees cut down in Saitama Prefecture, contributing to the effective use of underutilized resources. (Cooperation: Midoriya Tree Doctor Office, Inc.)
