Kagami-iwa rock at Mount Mitake, Slickenside formation at Mount Mitake, Japan
The polished surface of Kagami-iwa rock forms a natural mirror-like appearance on the mountainside, reflecting sunlight across the surrounding landscape of Kamikawa.
The geological formation emerged over 100 million years ago during the creation of the Hachioji tectonic line, leading to its recognition as a Special Natural Monument in 1956.
The rock formation stands near Kanasana Shrine, established in 100 AD, which maintains the tradition of mountain worship without a conventional shrine building.
Visitors can access the rock formation through a network of maintained trails connecting to the Mitake cable car station, which operates regular services throughout the day.
The geological structure represents one of the few designated slickenside formations in Japan, displaying distinct patterns created by ancient tectonic movements.
