The city says it processes more salted herring roe (kazunoko) than anywhere else in Japan, and the sunsets at Ogon Cape (黄金岬) are among Japan's "100 Best Sunsets".

Name origin
  • The name comes from the Ainu Rurumoppe (ルルモッペ), a name for the Rumoi River. The city splits it as ruru (潮, tide), mo (静, quiet), ot (入る, to enter) and pe (所, place). It translates the whole as "the place where the tide quietly flows in".2 The city's overview page instead glosses ot as "to be" (ある) and pe as "water" (水), and explains the name as a river where the tide reaches far inland.6
  • Japanese Wikipedia notes that there are several theories. Among them it singles out rur-mo-ot-pe ("tide–quiet–always there–thing (river)", i.e. "a river the tide enters deeply") as the natural reading, and says the city uses it.4 The subprefecture's summary gives a shorter version: a corruption of Rurumoppe, "from 'quiet river'".7 The accounts differ mainly on ot. The city profile reads it as "to enter"; the city's overview page and the Wikipedia gloss read it as "to be (always) there".
  • In Edo times the Matsumae trading post here was called the Rurumoppe basho (ルルモッペ場所). In 1869 the Meiji government renamed the area 留萌, first read Rumoe (るもえ).1 The kanji 萌 ("to sprout") is echoed in the city seal's sprouting-seed design.6

History
  • Prehistory. The 三泊漁港遺跡 site (at the 三泊 fishing port) shows that Jōmon people here lived by hunting at sea. It was designated a municipal historic site in 1999. Also held by the city: a late-Heian star-helmet fragment (星兜残欠), a municipal cultural property.10
  • Edo period. Ainu and Japanese lived side by side along this coast.4 In the Keichō era (1596–1614) the Matsumae domain opened the Rurumoppe basho to trade with the Ainu.2 Around 1789 Matsumae assigned the Rumoi post to its retainer 松前貢. Merchant contractors such as Suhara Kakubei (栖原角兵衛, from Kishū) later ran the region's fisheries.17
  • Herring and the Saga family. In 1844 Saga Heinojō (佐賀平之丞), eighth head of a fishing family from today's Kazamaura in Aomori, opened a herring fishery at Reuke (礼受). The family fished there for 113 years, until 1957. At its peak it ran 12 set-net operations (12ヶ統の建網) around Rumoi.1819
  • Shogunate and early Meiji. In 1855 the shogunate took direct control of western Ezo and the Akita domain guarded the area. In 1869 the area was renamed Rumoi and put under the Yamaguchi domain.1
  • Building the town. The village office was built at Kawakita in 1877, and 1877 counts as the city's founding. Rumoi Village absorbed Reuke Village in 1902 and became a town in 1908.1 The Owada coal mine (大和田炭鉱) opened in 1899 and closed in 1959.4 Settlers came in the Meiji era, but the sources consulted do not say which prefectures they came from.
  • Railway and port. The Rumoi–Fukagawa railway opened on 23 November 1910. Construction of Rumoi Port began the same year.201 The subprefecture office moved here from Mashike in 1914, and trains reached Mashike in 1921.1 The coastal line north (later part of the Haboro Line) opened to Ōtodo on 25 October 1927 and reached Onishika on 10 October 1928. The city chronology gives 1927 for Onishika.201 The port was completed in 1931 and opened to international trade in 1936.1 Igarashi Okutarō (五十嵐億太郎) is honoured as the "father of Rumoi Port".2
  • 1945. On 22 August 1945, a week after Japan's surrender, Soviet submarines attacked three evacuation ships off Rumoi: the Ogasawara Maru, Daini Shinkō Maru and Taitō Maru. More than 1,708 people died. This is the "Three Ships Disaster" (三船殉難事件). Records show that Stalin had planned a landing at Rumoi for 24 August.21
  • City status and the end of herring. Rumoi became a city on 1 October 1947. A Self-Defense Forces regiment (today's 26th Infantry Regiment) was stationed here in 1953.1 Herring stopped spawning inshore (群来, kuki) after 1954, and the herring fishery ended in 1957.2 Local processors switched to imported roe, for example from Canada.2 In the 1950s Rumoi Port handled almost all of Japan's kazunoko imports, and Rumoi firms held over 60% of Japan's tarako processing.4
  • Disasters. The 1958 Motomachi fire destroyed 252 homes.1 In August 1988 the Rumoi River flooded, causing ¥6.18 billion in damage and flooding 1,270 buildings above floor level.122 Record snow in 2013 paralysed traffic.2
  • Herring return. In spring 1999 herring spawned off Rumoi's beaches again for the first time in 45 years.12
  • Modern infrastructure. Rumoi Dam began operating in 2010.1 In 2016 the city passed the Rumoi City Kazunoko Ordinance (留萌市かずの子条例).2 Rail lost ground in stages. The Rumoi–Mashike line closed on 5 December 2016. The Ishikari-Numata–Rumoi section closed on 1 April 2023, leaving the city without rail. The rest of the Rumoi Main Line closed on 1 April 2026.20
  • Revitalisation. Rumoi IC opened on 28 March 2020, completing the expressway.231 Michi-no-Eki Rumoi opened on 11 July 2020.24 The indoor play centre Chairumo followed in April 2022.25 The outdoor activity base opened on 16 July 2026.13 On 3 October 2026 the city hosts the 14th National Michi-no-Eki Symposium.12

Geography & climate
  • Setting. Rumoi lies in northwest Hokkaido on the Sea of Japan, halfway along the coastal Japan Sea Orolon Line (日本海オロロンライン). The Shokanbetsu-Teuri-Yagishiri Quasi-National Park (暑寒別天売焼尻国定公園) stretches away to its south and north.2
  • Landforms. The city is built around the Rumoi River, which runs east–west with plains and hills on either side. The south is mountainous and the north has lower hills.6 Forest covers 175.61 km², about 59% of the city.2 The tallest of its main mountains is Mt Poroshiri (ポロシリ山, 730.5 m).4
  • Rivers and dam. The Rumoi River (留萌川) is 44 km long, drains 270 km² and rises on Mt Poroshiri. Rumoi Dam (留萌ダム) was completed in 2010 on its largest tributary, the Chibaberi River. It controls floods and supplies water.22 Its reservoir is Lake Chibaberi (チバベリ湖).26
  • Coast. Ogon Cape has rugged rock formations that look like stacked pillars. Golden Beach is about 1 km of sand.2711
  • Climate. The climate is typical of the Sea of Japan side. The Tsushima Current keeps it fairly mild for its latitude. Winter northwesterlies often exceed 20 m/s and whip up ground blizzards (地吹雪) that disrupt traffic.17 JMA normals for 1991–2020 at Rumoi:28
    • Annual mean temperature 8.0 °C (January −4.1 °C, August 20.9 °C)

  • Public finances. In FY2024, donations (寄附金, the category that includes furusato nozei) brought in ¥1.95 billion. That was 10.8% of general-account revenue, close to the ¥2.15 billion raised in city taxes.2
