Mount Rishiri (利尻山, Rishiri-zan) is a quaternary[2] stratovolcano located off the coast of Hokkaidō, Japan in the Sea of Japan. The extinct volcano rises out of the sea forming Rishiri Island. Because its cone shape resembles Mount Fuji it is sometimes referred to as Rishiri Fuji. It is one of the 100 famous mountains in Japan.

Mount Rishiri's opening festival is held annually on July 2 and July 3. This festival officially opens the climbing season.[3]

Geology

Mount Rishiri is made up of alkali and non-alkali mafic volcanic rock dating from the Late Pleistocene, 130,000–18,000 years ago. Otherwise it is covered in quaternary volcanic rock debris.[2]

Climbing route

The ascent of Rishiri is not suitable for novice hikers, it is challenging in places. There is a campsite partway up the mountain from the dock, and an unmanned hut located a short distance below the summit. There is also a small shrine at the summit. On clear days the view extends to Hokkaidō, the adjacent island of Rebun, and as far as Sakhalin Island in Russia.

The package of Shiroi Koibito includes a picture of Mount Rishiri arranged in the centre.
