About Tokai-Mura

Tokai Mura is a mountainous seaside village in the center of Japan’s Ibaraki prefecture. It is home to around 38,000 people.

What is a sister city? Why Tokai-Mura?

A sister city is a relationship or long-term partnership between two communities and two countries. The Idaho Falls-Tokai Mura sister cities program was established in 1981.

Tokai and Idaho falls are sister cities because they share a variety of similar traits. Both are mountainous and in the countryside, and are homes of major nuclear power plants. 

Celebrating Tokai-Mura in Idaho Falls

Since establishing a Sister City with Tokai Mura in 1981, the city of Idaho Falls has opened a Japanese Friendship Garden in their honor that the city, youth, and adult groups manage and care for year-round. It contains stone paths, pagodas, Japanese fencings, and a pavilion with a direct view of the falls. It is located in Idaho Falls on West Broadway next to Key Bank.
