About Yamagata

Yamagata is a prefecture located in the Tohoku region of Japan.
It is located in the southwest corner of Tohoku, facing the Sea of Japan. It borders with Niigata Prefecture and Fukushima Prefecture, Miyagi Prefecture and Akita Prefecture.
All of the borders are marked by mountains, with most of the population residing in a limited central plain.
17% of the area are designated as Natural Parks, Quasi-National Parks and Prefectural Natural Parks.

While visiting Yamagata, you may consider staying at one of the more popular hot spa areas in Japan, Ginzan Onsen. Here, you can still feel the Japanese traditional atmosphere with the view of the onsen accommodations (Japanese style hotels) still in business along the river side, just as it was from long time ago.

If you want to know what to eat in Yamagata, soba (Buck wheat noodle) in Yamagata is a must for all visitors! We do have soba all over japan, but having it here is just another story. It just tastes better.
