Kutchan 倶知安町

• Official explanation: 倶知安 spells "Kutchan", which comes from the Ainu Kussyani (クッシャニ). That was the old name of the Kutosan River (倶登山川), a tributary of the Shiribetsu. The town reads it as kut-san-i, "the place where (the river) flows out of a tube-like place". The same word also became Kudosani, the source of the river's present name, Kutosan. The name was officially announced in 1893, and the kanji were chosen by Hokkaido Government councillor Shirani Takeshi (白仁武).¹⁰
• Other theories: the Hokkaido Government's list of Ainu place names says the origin is hard to pin down.¹⁵ It records these readings:
  • kutu-sani, "muddy, cloudy river" (Nagata)
  • kut-san, "flowing out through a cylinder-shaped landform" (Chiri). Yamada notes that the land does not look like this.
  • Matsuura Takeshirō's gloss, "a fish-catching device", perhaps a tube-shaped basket trap
  • Yamada's tentative "(the river) that flows out at the cliff"
  • kut-sam-un-pet, "the river beside the rock cliff", a stream at Kutchan Pass (倶知安峠), cited in a book on the origins of station names
• Other names in the town:
  • Kanbetsu (寒別): from nupuri-ka-un-pet, "the river that goes up into the mountains".¹⁶
  • Iwaonupuri: iwaw-nupuri, "sulfur mountain". The list gives this reading its highest confidence rating.¹⁷
  • Niseko Annupuri: named after the Niseikoanpet River, "the river facing the cliffs" or "the river in the gorge".¹⁸
  • Hirafu (比羅夫): the town's chronology begins with the Nihon Shoki's account of Abe no Hirafu (阿倍比羅夫) appointing a governor at "Shiribeshi" (後方羊蹄) in 659.⁵ The general is traditionally taken as the source of the district's name, but the town does not say so (unverified).

• Before settlement: in 1858 Matsuura Takeshirō climbed Mt. Yōtei, and he wrote about it in his Shiribeshi Nisshi.⁵ In 1861 Satō Niemon of Senbokuya, which held the trading-post contract at Iwanai, mined sulfur on Iwaonupuri.⁵ The town's records say little about Ainu life in the basin.
• Settlement:
  • The "Kutchan plain" was placed in the Imperial forest in 1890 and released for settlement in 1894.⁴
  • Manabe Hamasaburō (真鍋浜三郎) and five others began clearing land on 19 May 1892, and a group of 15 followed two days later. By the end of the year 47 households had settled.⁵ The town's statistics book dates the start of settlement to 17 May instead.⁴ The sources checked do not say where the settlers came from.
  • In 1894 Yamada Kunikichi found the hot spring that became Yamada Onsen.⁵
• Rail and administration:
  • The private Hokkaido Railway opened Kutchan and Hirafu stations on 15 October 1904. The line is now the Hakodate Main Line.⁵
  • The Shiribeshi Subprefecture office opened in Kutchan in 1910.⁵
  • A light railway to Kyōgoku opened in 1919.⁵ It was folded into the Iburi Line in 1944.¹⁹ The Kutchan engine depot, which served three lines, had 259 staff at its peak.²⁰
• Skiing: on 16–17 April 1912, Major Theodor von Lerch's party demonstrated skiing on the Asahigaoka hill. They then attempted Mt. Yōtei on skis, continuing on foot from the fourth station to the summit.⁵
• Wartime: in 1943 a fire at the Hotei-za theater killed 208 people.⁴ From 1941, Nakaya Ukichirō's Hokkaido Imperial University team studied aircraft icing on the summit of Niseko Annupuri, using a Type 96 fighter and then a Zero. The Zero's right wing was recovered from a valley in 2004.²¹
• Postwar:
  • The Ground Self-Defense Force came to Kutchan in 1955.⁵
  • Ski lifts opened at Hirafu and Asahigaoka in 1961, according to the statistics book.⁴ The town's chronology dates the Asahigaoka lift to February 1965 instead.⁵
  • The Niseko range became part of a quasi-national park in 1963.⁵
  • In 1964 neighboring Kaributo became Niseko Town. Kutchan agreed to the name only after mediation by the head of the subprefecture.⁵
  • The Iburi Line closed on 31 October 1986.⁵
• Resort boom: the Hanazono slopes opened in 1992. Australian investors came in 2004, and Hong Kong capital took over in 2007.⁴ The G20 Tourism Ministers' Meeting was held at Park Hyatt Niseko HANAZONO in October 2019.⁵
