Admire the natural rock formations of Nagatoro Iwadatami

Just five minutes on foot from Nagatoro Station takes you to one of Saitama’s most spectacular natural wonders - Nagatoro Iwadatami. This beautiful gorge features layers of rocks that are reminiscent of stacks of ancient Japanese tatami mats, hence the name Iwadatami (“rock tatami mat”).

They were formed by the large scale movement of the Earth's crust and are visited by scholars from across Japan, with Nagatoro sometimes referred to as “The window of the Earth”.

Enjoy a walk along the river banks to admire these layers of flat rock, which have formed natural paths and steps.
