Yashima Wetland

On top of Kirigamine Plateau, an expanse of green embroidered with alpine flowers

Yashima Wetland is a picturesque marsh encased in the grassland hills of Kirigamine Plateau.

At a first glance it appears as a green meadow interrupted by a few crystalline pools, but better not try to tread on it, beneath the surface lies an 8-meter-deep peat deposit which accumulated over the course of 12,000 years.

The area is habitat to many small animals such as cute little frogs and lovely butterflies, and in the summer, you can find countless species of colorful alpine flowers.

A wooden hiking trail runs the entire length of the wetland which can be circled with ease in about 90min.

The best seasons to visit are summer, between July and August, and autumn, from early to late October. In summer the green of the hills and the blue of the sky reflected in the water dominate the scene, while in autumn yellow and orange take over, tinging the landscape with warm colors.
