    • From Sapporo: about 4 h 30 min by limited express
    • From Asahikawa: about 3 hours
    • From Wakkanai: about 50 minutes by local train
  • Bus. A local bus runs from Toyotomi Station to the onsen in about 10 minutes.63 It is Engan Bus route 32 (豊富幌延線). The tourism association's pages give fares of ¥330 or ¥340, but Engan Bus revised its fares on 1 October 2025, so check the current fare.64633 When no bus runs, the town operates a reservation-only shared taxi between the station and the onsen. No scheduled bus links Wakkanai and Toyotomi.65 Engan Bus's Tokkyū Haboro leaves Sapporo Station (stop 32) at 13:00, 15:00 and 17:30. It reaches Toyotomi Onsen about 5 hours later. The fare is ¥7,100 and seats must be reserved. The timetable from 1 October 2026 keeps these departure times, with arrivals 5 minutes later.66
  • Road. National Route 40 runs through the town. The free Horotomi Bypass (幌富バイパス) opened in 2010 and runs 10.9 km from Horonobe IC to Toyotomi Sarobetsu IC.67 It joins the Toyotomi Bypass (豊富バイパス), which opened in November 2004.675
  • Air. The nearest airport is Wakkanai, about 2 hours from Haneda and 1 hour from New Chitose.62 Sōya Bus's airport bus into Wakkanai takes about 35 minutes and costs a flat ¥800.68
  • Ferries. Heart Land Ferry boats to Rishiri, Rishirifuji and Rebun leave from Wakkanai.63
  • Getting around. Rental cars and bikes are available at Yunomori Pokke.59 A car is the easiest way to link the wetland, the coast, Kabutonuma and the onsen.

Practical tips

  • When to go. Late June to early July for Ezo daylilies, and spring or autumn for migrating geese and swans.2 The pasture has cattle from May to October,20 and the ski area opens mid-December to mid-March.41
  • Seasonal hours. The Sarobetsu Wetland Center opens 9:00–17:00 daily from May to October. From November to April it opens 10:00–16:00 and closes on Mondays and over New Year.26 The campgrounds are open only from 1 May to 30 September.48
  • Hot-spring cures. Contact the Concierge Desk before a long stay.51 A 1998 study by the Hokkaido Institute of Public Health reported healing effects.15 The onsen pamphlet says the effects are not guaranteed for everyone.69
  • Winter. Expect strong northwest winds and snow from mid-November to mid-April.31 Check road reports before crossing the open plain.
  • Wildlife. Ezo deer live in the area, so drive carefully at dusk.38 Carry a bear bell in the hills, as elsewhere in northern Hokkaido.
  • Accommodation tax. Since 1 April 2026 Hokkaido has charged ¥100–500 per person per night. At the town-run Yukaijuku and the Kabutonuma cabins it is ¥100, and tent and RV sites are exempt.70

Name origin
  • The name is a loose translation of the Ainu river name Ebekorobetsu (エベコロベツ). The Ainu form is ipe-kor-pet (イペコロペッ), "river that has food (fish)".22
  • In 1908 the subprefecture asked for a proper name for the new town site. Wikipedia calls it the Rumoi Subprefecture, but in 1908 the office was still the Mashike Subprefecture; it moved to Rumoi and took that name in 1914.65 The residents' association took ipe-kor-pet to mean "plenty of food" and chose 豊富, which means "abundance".6
  • Place-name scholar Yamada Shūzō noted that two Ebekorobetsu rivers, the Panke (lower) and Penke (upper), flow through the area. He called them muddy rivers in the marsh and recorded a local driver's comment that they hold few fish. The Hokkaido Government's Ainu place-name list rates this derivation at level B.22
  • The kanji 豊富 are usually read hōfu ("abundant"), and the town uses this in its slogan いいとこ"ほうふ"豊富町.1

History
  • Ainu era. The sources checked record no archaeological sites here. Ainu names survive in the rivers and marshes (see Ainu heritage).
  • 1869–1878. In 1869 the area was placed under the Mito domain. In 1870 a government lodging house was built at "Wakkasakunai" (ワッカサクナイ), today's Wakasakanai. Saru Village (沙流村) was created in 1878.5
  • 1903–1919. Umemura Shōjirō brought a group of 12 households from Gifu Prefecture to settle at Kabutonuma in 1903. Saru still had only 614 people in 1909. In 1919 it merged into Horonobe Village.5
  • 1924–1935. Kabutonuma Station opened in 1924.23 Murai Mining began drilling for oil in 1925. On the night of 17 May 1926, hot water burst out of the test well with natural gas from 960 m down. The Soya Main Line was completed that September, and Toyotomi Station opened on 25 September.1524 Locals first bathed in a thatched hut by the well, and eight inns soon opened.3 A gas-engine power plant brought electricity to the town in 1932.15
  • 1937–1972: coal. Nisso Mining (日曹鉱業) opened a coal mine. The town handbook gives 1937 for the opening, and Wikipedia gives November 1936.56 A private railway ran from the mine to Toyotomi Station from 1940 to 1972.24 Mitsubishi Mining started a second mine in 1947. The Nisso mine closed in July 1972.5
  • 1940–1959. In September 1940 the old Saru area split from Horonobe and became Toyotomi Village. It had 1,291 households and 7,521 people. The village moved to Soya Subprefecture in 1948 and gave its Tenkō and Akebono districts to Wakkanai in 1950. It became a town in January 1959.5
  • 1962–1974. A land-improvement project on the Sarobetsu Plain began in 1962, and a large-scale pasture project in the western Tenpoku region in 1966. The area became a quasi-national park in 1965 and Rishiri-Rebun-Sarobetsu National Park on 20 September 1974.525
  • 1983. The town set up a liaison office in September for the Korean Air Lines Flight 007 disaster.5
  • 1988–2011. The Fureai Center bathhouse opened in 1988. Toyotomi Onsen was designated a National Health Resort Hot Spring (国民保養温泉地) in 1992.15 The Sarobetsu Plain became a Ramsar site in November 2005,6 and the Sarobetsu Wetland Center opened in 2011.26
  • 2015–2021. Toyotomi Onsen joined the "100 Best Hot Springs of Japan" (日本の名湯百選) in 2015. In 2017 the town opened the Yunomori Pokke visitor center and registered as a gas retailer.15 Tokumitsu Station closed on 13 March 2021.27
  • 2023–2026. Air Water and Toda Kogyo began a project in 2023 to make hydrogen from the town's unused natural gas. Their plant was finished in September 2025.155 Toyotomi Onsen marked its centennial with a ceremony on 16 May 2026 and a festival the next day.15

  • Rivers and wetland. The Sarobetsu River meanders across the town. It is joined by the Menashibetsu and Shimo-Ebekorobetsu rivers, then turns along the coast to the Teshio River. Its basin forms a wide plain.11 About 10,000 years ago the area was a lagoon open to the sea. The wetland grew from peat that has built up over more than 6,000 years. It is the third-largest wetland in Japan.2 Penke-numa lake (ペンケ沼, 1.27 km²) is shared with Horonobe.10
  • Land use. Forest covers 32.1% of the town, fields 20.2%, wilderness 19.1% and pasture 11.5%.5

    • A cow from the Satō Farm (佐藤牧場) set a national record of 96 points in the Holstein Association of Japan's classification.32

  • Energy. Hokkaido Electric ran a gas-turbine power station in the town from 1957 to 1975. The town became sole holder of the mining rights in 2013. Since 2017 it has sold gas to a yogurt factory in the industrial park.15
  • Tourism. The town counted 183,438 visitors in FY2024, down from 316,238 in FY2013, the highest year in the handbook's FY2011–2024 table.

Ainu heritage

Little is documented about Ainu history within today's town. No archaeological sites or Ainu cultural facilities were found in the sources checked. What remains is mainly place names:

  • Sarobetsu (サロベツ). From sar-o-pet, "river in the reed marsh". Yamada notes that the river still flows through wide, low marshland full of reeds. The list rates this derivation at level A.45
  • Ebekorobetsu → Toyotomi. From ipe-kor-pet, "river that has food (fish)"; see Name origin.22
  • Penke-numa and Panke-numa. Two large lakes east of the Sarobetsu River. Their names come from penke-to ("upper lake") and panke-to ("lower lake"). Panke-numa and the nearby station name Shimonuma lie in Horonobe.4610
  • Wakasakanai (稚咲内). Written ワッカサクナイ in 1870 records, which points to an Ainu origin.5 A common reading is wakka-sak-nay, "river without drinking water" (unverified).

Sister & friendship cities

No formal sister city was found. The town has these partnerships:

  • Taketa (Ōita) and Semboku (Akita). On 22 July 2015 the three municipalities signed a "Hot-Spring Power Regional Cooperation Agreement" (温泉力地域協力協定). All three have hot springs known for cure bathing.32
  • Minato City, Tokyo. An exchange partnership since 2016, shared with the other Soya towns and villages. Events include Toyotomi Onsen bathing weeks at Minato's public bathhouses.532
  • Hokkai-Gakuen University. A comprehensive partnership agreement signed in June 2021.5
