岩井滝

Iwai waterfall descends over dark volcanic rocks, creating white water patterns in a mountainous landscape. The water flows through multiple levels of stone before reaching a natural collection area below.

The waterfall developed through erosion in volcanic rock over extended periods. This ongoing geological process has exposed layers of ancient stone formations millions of years old.

The waterfall plays a role in local Shinto practices, and visitors may witness water purification ceremonies that take place during summer festivals in the area.

The area around the waterfall is organized with well-marked paths and safety railings to make viewing comfortable and secure. Parking is available nearby, and the site is accessible throughout the year.

During winter months, the waterfall freezes partially, forming natural ice structures while other sections continue to flow. This seasonal change gives the site a different appearance depending on the time of year.
