Otaru

is a city and port in Shiribeshi Subprefecture, Hokkaido, Japan, northwest of Sapporo. The city faces Ishikari Bay and the Sea of Japan, and has long served as the main port of the bay. With its many historical buildings, Otaru is a popular tourist destination. Because it is a 25-minute drive from Sapporo, it has recently grown as a bedroom community. As of July 31, 2023, the city had an estimated population of 107,432 and a population density of 441 persons per km² (1,100 persons per mi²). The total area is . Although it is the largest city in Shiribeshi Subprefecture, the subprefecture's capital is the more centrally located Kutchan. History The city was an Ainu habitation, and the name "Otaru" is recognised as being of Ainu origin, possibly meaning "River running through the sandy beach". The very small remaining part of the Temiya Cave contains carvings from the Zoku-Jōmon period of Ainu history, around A.D. 400. Mount Akaiwa (Northwest part of Otaru) is memorialized in the Ainu tradition in the story of Sitonai, village chief's teenage daughter who had slain a white snake from the mountain's cave that demanded sacrifices of girls every year. The legend explains the name of a big cave on Mount Akaiwa, Hakuryu Gongen Cave (白竜権現洞窟, lit. White Dragon Gongen Cave) and the reason why a shrine was built on the mountain (to protect the village from being haunted by the snake). Otaru was recognised as a village by the bakufu in 1865, and in 1880 the first railway line in Hokkaido was opened with daily service between Otaru and Sapporo.
