This museum is housed in a historical building repurposed from the former Oniwaki Village Office building constructed in 1913. Exhibits are divided into four sections, each featuring the nature and creatures of Rishiri, the days when indigenous Ainu people lived on the island and called it Ri-sir (Ainu for “island with a high peak”), modern days, and days with thriving herring fishery. Behind the facility is an alpine botanical garden. The museum is more than a popular tourist destination; it is also a haunt for local residents interested in the town’s history.
