I found something at Earth Plaza!

Earth Plaza (Kanagawa Prefectural Kanagawa Plaza for Global Citizenship) is a facility with three objectives: to develop children's rich sensibilities, to foster a sense of global citizenship, and to support international activities.

We also hold large-scale exhibitions on themes such as international understanding, peace, and the environment, as well as film screenings, workshops, field trips, and educational and legal consultations for foreigners.

The permanent exhibition room on the 5th floor is the "Children's International Understanding Exhibition Room," which displays everyday items, costumes, musical instruments, etc. from countries around the world, the "International Peace Exhibition Room," which displays materials related to war, conflict, and refugee issues,
The museum is made up of a "Children's Fantasy Exhibition Room" where children can play using all five senses. On the second floor, there is a video library with books and videos on international understanding and international cooperation activities, as well as an information forum.
