Things to Do in Nagatoro

Nagatoro Iwadatami is a stunning natural rock formation along the Arakawa River, featuring layered crystalline schist rocks that resemble traditional tatami mats. These unique geological formations, shaped over millions of years, create a dramatic riverside landscape that's particularly beautiful during autumn foliage season. Visitors can admire the rocks from riverside walking paths or get an up-close view by taking a traditional boat ride down the rapids.
