In September 1991, a large wooden box with the inscription Shishigashira Senhoshi (shishi lion head Senhoshi) was found in the community hall of the Senhoshi Nagahama district in the southwest part of Rishiri Island.
The find was made by Nishiya Eiji, curator of the Rishiri Town Museum, and a curator at the Hokkaido Development Memorial Hall (now Hokkaido Museum).
Nishiya was puzzled by the shishi lion's head, which he had never seen before.
There had long been a legend that there must be a shishi lion's head somewhere in the village, brought by the ancestors who had come from Tottori. However, there was no one who knew what kind of shishi lion's head it was.
One small clue was given by Morimoto Kiyoe (83 at the time), a descendant of those who came to the Nagahama area from eastern Tottori during the Meiji period (1868-1912), who was still alive and well. Morimoto said that his uncle had taught him to dance when he was a child.
Nishiya found a possible connection to Tottori and contacted the Tottori Prefectural Museum.
This shishi lion's head was a kirin shishi lion, a shishimai lion dance kagura that is still performed in Inaba, a region in the eastern part of Tottori Prefecture. The shishi lion head, which looks different from an ordinary kagura shishi lion, is a kirin, a mythical spirit animal from Chinese folklore.
Morimoto's family came to Nagahama from Kabutoyama, Tottori City (present-day Satoni) when his grandfather, Kintaro, was still living there in 1894. However, there were no kirin shishi lions in Satoni. The uncle who taught Morimoto the shishi lion dance was born in Akisato, a town next to Satoni. When he researched Akisato, he found a kirin shishi lion there.
The kirin shishi lion was introduced to Rishiri Island during the Meiji period (1868-1912). This discovery created quite a stir in Tottori as well.
In the summer of 2001, a group from Akisato visited the island. They expressed their wish that the kirin shishi lion would be revived in Rishiri and that they would do their utmost to help.
Nishiya invited young people in their 30s and 40s in the Nagahama area to get together and try to awaken the kirin shishi lion. In June 2003, they began rehearsing by watching videos provided by Akisato.
In January 2004, members from Rishiri first visited Tottori for dance practice and social exchange, and two full days of training were carried out.
Then, on June 20, 2004, the stage was set for the Senhoshi Nagahama Shrine festival on Rishiri Island. In the evening, the kirin shishimai lion dance was finally revived in Nagahama for the first time in almost 100 years.
The origin of the kirin shishi lion of Rishiri was revealed between the time the members went to Akisato, Tottori City, to practice and this revival dance. The mystery was uncovered by Morimoto Masayuki (then 80 years). He is the son of Morimoto Kiyoe.
When Masayuki, a resident of Asahikawa, came across reports that members of the island were going to Tottori to revive the kirin shishi lion, he remembered what his father had told him about this shishimai lion dance and asked questions to his relatives who had come from Tottori to solve the origin of the shishi lion head.
Morimoto Kintaro's daughter married someone else who had moved to Rishiri from Tottori. After their marriage, they returned to their hometown in Tottori, and later went back to Rishiri, bringing back a kirin shishi lion. But why did they bring back the kirin shishi lion, which was a large item to bring with you when traveling?
Masayuki though his grandfather Kintaro was a leader of the community, and as his life in Nagahama became more settled and relaxed, he decided to establish the kirin shishi lion from Tottori on the island. He probably asked his parents, who remained in Inaba, to help him gather supplies for the kirin shishi lion.
