Iwamurada Hikarigoke Sanchi

The Iwamurada Hikarigoke Sanchi is a protected natural site in Nagano Prefecture where the rare Schistostega pennata moss species thrives across rocky ground. Dense moss formations cover the area, creating a specialized habitat maintained under careful conservation management.

The site received official designation as a natural monument to safeguard its rare moss populations from human disturbance. This protection framework has allowed the ecosystem to remain largely undisturbed over time.

This location functions as an educational center where students and researchers study the growth patterns and biological characteristics of luminous moss species.

Advance permission from local conservation authorities is required before visiting this protected area. Visitors must follow designated paths and guidelines carefully to avoid damaging the delicate moss growth.

The Schistostega pennata moss found here has the remarkable ability to reflect light and glow in low-light conditions. This optical property makes the site particularly interesting to botanists and researchers studying light adaptation.
