The purpose of this paper is to reveal the characteristics and changes in animal utilization based on the minimum number of individuals (MNI) of animal remains excavated from archaeological sites on Rishiri Island, Hokkaido. As a result, it was able to show that on Rishiri Island, 1) a high degree of marine adaptation probably occurred by the middle of the Jomon period (earlier than the end of the late Jomon period to the beginning of the Epi-Jomon period as evidenced by animal remains), 2) dog breeding started for the purpose of using as food and materials from the end of the late Jomon period to the beginning of the Epi-Jomon period, 3) pig breeding started at the latest during the Towada and Kokumon periods of the Okhotsk culture, and 4) many abalones were harvested intensively, processed, and traded in the early modern period, and this shows that Rishiri Island was integrated into the commercial economy that covered all of Japan. Although these things were already roughly understood, it has become possible to understand more concretely the characteristics and changes in animal utilization on Rishiri Island based on a common criterion, MNI.

In this paper, we use the “Pyojurok,” a record of the movements of the Koreans Lee Jihang and his party who were washed ashore in Ezochi (Hokkaido) in 1696 (Genroku 9), as a clue to identify the place names recorded in it while comparing it with the Japanese record “Fukuyama Hifu.” The first place where they washed ashore is likely to have been Rishiri Island, as it is land with the snow-capped peak of “Taizan (A big and magnificent mountain)”. It is highly likely that they accessed the north side of Rishiri Island, and based on the shabby houses, houses, and dried whale meat that were sighted, they were estimated to have arrived somewhere between Kutsugata and Tanetonnai (Tanetomicho). From there, they then traveled across a small sea to Rebun Island. In Rebun Island, the name is based on the names “Che-mokots” and “Chom-mokots” that they heard from the Ainu. From “Chom-mokots”, you can see a long, wide expanse of land and Mt. Rishiri to the southeast. I think they are derived from Chashi-kots (Remains of an Ainu fort), and I think they refer to the southern areas of “Motochi,” “Sashitoji,” and “Teshikari.” In addition, contemporary historical documents such as the Matsumae Ezo Map and Kuunen’s Ezochi Nokyo-ki contain records of products of the time, such as Ishiyaki-Kujira(Whale meat is dried after cooking it on a stone to extract the oil), Tonotomari (Motodomari) Akinaiba was set up with Matsumae was established, and the situation of the Ainu. In conclusion, I have been able to largely prove that Lee Jihang and his party were shipwrecked on Rishiri Island, traveled to Rebun Island, and then reached Soya.

Synanthedon formicaeformis was previously recorded from Rebun Island, Hokkaido, Japan. Here, we report another species of the genus Synanthedon that was photographed on the island. The moth found could be a female of S. scoliaeformis japonica, based on the morphology of its antennae and abdomen, although the species is known to be very rare in Japan.

We made a list of carabid species (Coleoptera, Carabidae) known from Rebun Island based on literatures, collecting research and specimen research in museums and personal collection. Totally, 85 species are recorded from Rebun Island including 31 species that newly recorded from Rebun Island.

Two males and one female of the Japanese mitten crab, Eriocheir japonica (de Haan), were captured in the park’s pond on Rishiri Island. This artificial pond is located about 600 meters from the sea and is connected to the sea via a culvert with fire tanks, and an inoperable facility for wastewater treatment. Although this is the first record of freshwater crabs from this island, further investigation is needed to clarify these crab’s origin.
