Tobetsu 当別町

• The town's official explanation is that 当別 comes from the Ainu Tōpetsu (トウペツ), "a river coming from a marsh" (沼から来る川).³¹
• Place-name scholar Yamada Hidezō (山田秀三), as cited by Japanese Wikipedia, gives the original form as to-pet (トペッ), "marsh–river." He explains the name by the many marshes that once filled the basin, which is now paddy land.²²¹⁰ English Wikipedia translates it as "river from marsh."²³
• The Tōbetsu River also had an older Ainu name, chiw-as-pet (チワシペッ), "the river where waves rise."²²

• Ainu era: The sources consulted document little about Ainu settlements or archaeology in Tobetsu. Japanese Wikipedia says only that in the Edo period the area, like neighboring Atsuta, was a place of trade with the Ainu.¹⁰ The main evidence of Ainu presence is in place names (see Name origin and Ainu heritage).
• 1868–1869, the Date decision: The Iwadeyama Date house belonged to Sendai Domain, which fought on the losing side in the Boshin War (1868–69). Afterwards Iwadeyama's holding was cut from 14,000 koku to 65 and its retainers lost samurai status, so Kunnao turned to settling Hokkaido.²⁴²⁵ In 1869 Date Kunnao was assigned Sorachi District (空知郡).²⁵ In the 9th month of 1869 the house announced its plan to move all its retainers to Hokkaido.¹ Sorachi proved impractical to settle. After negotiation the group was allowed to use a landing place at Shippu (聚富, now Atsuta in Ishikari City).²⁵
• 1871–1879, three migrations: A first party of about 180 left Iwadeyama in the 3rd month of 1871, landed at Muroran in the 4th month, moved to Shippu and surveyed the Tōbetsu area in the 5th month.¹²⁵ A second party of 180 left in the 2nd month of 1872, and the settlement was named Tōbetsu Village in the 8th month of that year. The Kaitakushi (Colonization Commission) opened a school here in 1873. A third party of 250 settled at Tsuishikari (対雁) and Rokkenchō (六軒町) in 1879.¹ (The tourism association says Kunnao sought new land to support a band of 736 retainers.²⁴)
• Recognition: Emperor Meiji received Kunnao during his 1881 inspection tour of Hokkaido. A government flax mill opened in 1889.¹ Kunnao died in January 1891. In 1892 his former retainers petitioned to found the Aso Shrine (阿蘇神社), which later became Tōbetsu Shrine. Kunnao was posthumously given Senior Fifth Rank (正五位) in 1915.²⁵
• Floods and growth: The great Ishikari River flood of September 1898 affected 1,415 people in Tobetsu. The village became a second-class village in 1902 and a first-class village in 1907.¹ Kunnao's younger brother Date Kunishige (伊達邦成) had led the Watari Date house to what is now Date in 1870.²⁶
• Railways: The Etō light railway (江当軌道) reached Tobetsu in 1927. The Sasshō Line opened from Sapporo to Tōbetsu in November 1934 and was completed in October 1935.¹
• In literature: Honjō Mutsuo (本庄陸男), born in Tobetsu in 1905,²⁷ wrote the novel Ishikari-gawa (石狩川, "The Ishikari River"). It follows the Iwadeyama retainers who arrived in 1871 and their fight with the flooding rivers. It was serialized from September 1938 to March 1939 and published as a book in May 1939.²⁸ The town's chronology dates it to May 1938.¹ A literary monument to it was unveiled in July 1964.¹
• Postwar: Tobetsu became a town on 1 July 1947.¹⁰ Aoyama Dam (青山ダム) was completed in 1963 (1964 in Japanese Wikipedia).¹²² Higashi-Nippon Gakuen University opened its Tobetsu campus in 1975. It had been founded in 1974 and took its current name, Health Sciences University of Hokkaido, in 1994.¹²⁹
• The Swedish connection: A private developer drew up the "Sweden Village" plan in 1979. Plots went on sale in 1984 and the first residents moved in during autumn 1985.¹² The Swedish Exchange Center opened in August 1986.¹ The sister-city agreement with Leksand was signed on 5 October 1987. The town says the link came about after the governor of Sweden's national investment bank remarked that Tobetsu looked like suburban Stockholm, and at the wish of King Carl XVI Gustaf to deepen ties with Japan.²
• Suburban growth: Sapporo Ohashi Bridge (札幌大橋) opened in 1988. Dōmin no Mori opened in stages: the Kamuishiri zone in 1990 and all five original zones by 1993, with the Aoyama-chūō zone added in 2004. The population passed 20,000 in 1996, and ROYCE' moved its factory here in 1999.¹¹³
• 2000s–2010s: Tobetsu became sister towns with Iwadeyama (now part of Ōsaki, Miyagi) in October 2000 and with Uwajima in July 2009. Tobetsu Dam was completed and the Sōen–Hokkaido-Iryōdaigaku section of the Sasshō Line was electrified, both in October 2012. The 15.4 km Route 337 Tōbetsu Bypass opened fully to four lanes in January 2016, and the Michi-no-Eki opened in September 2017.¹
• 2020s: The town marked 150 years since its founding in 2020.²⁶ The Hokkaido-Iryōdaigaku–Shin-Totsukawa section of the Sasshō Line closed on 7 May 2020, and a replacement bus to Tsukigata began in April.¹³⁰ A "historic brother city" pact with Date was signed on 9 October 2020.²⁶ ROYCE' Town Station opened in March 2022. In April 2022 the town's elementary and junior high schools merged into the combined compulsory school Tōbetsu Gakuen.¹ ROYCE' Cacao & Chocolate Town opened fully on 4 August 2023. On 1 April 2025 parts of Bitoe and Tōbetsubuto were renamed Royce Town (ロイズタウン), giving the factory the address Royce Town 1-1.¹³ The university plans to move out in 2028.²¹

• Shape and terrain: The town lies in the north of Ishikari Subprefecture.²³ It is long and narrow, about 47 km north to south and 27 km east to west, going by the town's extreme coordinates (43°09′–43°35′N).³ The north is mountainous and the south lies on the flat Ishikari Plain.¹⁰²³ Forest covers 26,478 ha, and cultivated land 8,420 ha, of which 6,070 ha is paddy.¹⁷

• Mountains: The main peaks are Pinneshiri (ピンネシリ, 1,100 m), 待根山 (1,002 m), Kumaneshiri (隈根尻山, 971 m) and Kamuishiri (神居尻山, 947 m). Lower hills include Sakkurai-yama (察来山, 590 m).¹⁰ Pinneshiri stands on the Shintotsukawa border. Its Ainu name means "male mountain" and is usually paired with a Matineshiri, "female mountain."³²

• Rivers and lakes: The Tōbetsu River (当別川) is 72.5 km long and drains 309.5 km². It rises at the foot of Sakkurai-yama (察来山) on the northern border with Shintotsukawa, passes through Aoyama and Tobetsu dams, flows south of the town center and joins the Ishikari River near Bitoe (ビトエ).²² Two dams stand on it:

  • Aoyama Dam (35.5 m), built for irrigation²²
  • Tobetsu Dam (当別ダム), completed in October 2012. It is a 52.7 m trapezoidal CSG dam, a Japanese-developed design built from cemented sand and gravel, and it supplies water to Sapporo, Otaru, Ishikari and Tobetsu. Its reservoir is Tōbetsu Fukurō-ko (当別ふくろう湖, "Owl Lake").²⁰³³

• Protected land: Dōmin no Mori (道民の森) is a prefectural forest park of 11,889 ha across Tobetsu and Tsukigata.¹⁸ The tourism association calls it one of the largest in Japan.⁹ No national or quasi-national park was found in the town.

• Climate: JMA has no temperature station in Tobetsu. A nearby full station is in neighboring Shinshinotsu (新篠津), 9 m above sea level on the same plain. Its 1991–2020 normals are:

  • annual mean temperature 7.3 °C, with January at −6.1 °C and August at 20.8 °C
  • annual precipitation 1,147.6 mm
  • annual snowfall 820 cm, with a normal peak snow depth of 131 cm³¹

  Records there are a high of 35.5 °C (25 August 2023), a low of −27.0 °C (7 February 1998), a deepest snow cover of 213 cm (16 January 2012) and a wettest day of 173 mm (4 August 1981).³⁴ Treat these as indicative for the southern farmland. The northern mountains are probably colder and snowier (unverified).

  • JA Kita-Ishikari (JA北いしかり) grows the wheat varieties Yumechikara and Kitahonami, and calls its wheat "No. 1 in Ishikari Subprefecture," with one of Hokkaido's larger acreages.³⁶¹⁶

• Flowers: Lilies, baby's breath, sunflowers and carnations lead about 30 flower crops. JA says it is a top-class producer in Hokkaido.¹⁶ The town says its flowers are trusted by the market for joint grading and shipping, and it has been recruiting new flower farmers.¹⁵ In 2020, 75 farm businesses grew 66 ha of flowers.¹⁷

• Vegetables and livestock:

  • Pumpkin: JA Kita-Ishikari says its pumpkin acreage is in Hokkaido's top five.
  • Broccoli: shipped June to October.
  • Asparagus: harvested mid-May to late June.
  • Beef cattle: many animals grade A5.¹⁶

• Manufacturing: Shipments totaled ¥30.6 billion (2024 Economic Structure Survey), and the town had 554 business establishments in 2021.¹ ROYCE' Confect's Royce Town factory is the best-known plant.¹³

• Workforce (2020 Census): 1,082 people worked in primary industry, 1,300 in secondary and 4,932 in tertiary.¹

• Tourism: Visitors in FY2025 totaled 2,128,500, up 12.5% on FY2024. Almost all were day-trippers from within Hokkaido. Only 14,500 stayed overnight. August was the busiest month, at 320,200.³⁵

• Population trend: The population passed 20,000 in 1996. The 2025 preliminary Census count was 14,949.¹⁶ In FY2024 there were 48 births and 216 deaths. Moves in (688) and out (696) nearly balanced.¹ The town's slogan is "a town bustling with child-raising families, where people can live with peace of mind" (子育て世代でにぎわう安心してくらせる町). Its measures include:

  • the Tōbetsu Gakuen compulsory school
  • home-purchase subsidies
  • a new branch office in Nishi-Tōbetsu (opened 2024)¹

• Looming change: The Health Sciences University of Hokkaido plans to move all its faculties to Hokkaido Ballpark F Village in Kitahiroshima in 2028.²¹²⁹ The campus has anchored the town since 1975.

• Shrines: Tōbetsu Shrine (当別神社, Motomachi 51-12) enshrines Date Kunnao as a god of pioneering, learning and literature. He was known as an educator and poet.⁵⁰ Other shrines include Benkebetsu Shrine (弁華別神社) and Nishi-Tōbetsu Shrine (西当別神社).¹⁰
• Samurai heritage: The Tōbetsu Date Memorial Hall (当別伊達記念館) displays Date family belongings and pioneer-era records. Next to it is the Date Residence Annex (伊達邸別館), built to host court nobles and other distinguished guests who came to see the settlement the lord was building.⁵¹ The Kaitakushi opened a school in Tōbetsu in 1873, only two years after settlement. The tourism association cites this as proof of Kunnao's emphasis on learning.²⁴¹
• Swedish culture: The Swedish Exchange Center (スウェーデン交流センター) hosts exhibitions and talks on Swedish industry and culture. It sells blown glass and woodcraft and has a library corner.⁵² Exchanges with Leksand include:
  • reciprocal visits
  • youth ice-hockey teams
  • junior-high and high-school student exchanges
  • economic delegations²

The sources consulted document little about Ainu history, archaeological sites or living traditions within Tobetsu, and no dedicated Ainu cultural facility was found in the town. Ainu language survives in place names:

• the town's own name, Tōpetsu/to-pet³²²
• chiw-as-pet, the Tōbetsu River's older name²²
• Pinneshiri, "male mountain," on the northern border³²
