Iwanai 岩内町

いわないちょう

Iwanai is an old Sea of Japan port at the western base of the Shakotan Peninsula. Herring made it rich, and a fire in 1954 burned about 80% of the town.123 Today visitors come for its seafood, its hot springs at the foot of Mt. Iwanai, and the art of Kida Kinjirō, the fisherman-painter who lived here all his life. The town also calls itself the root of Japanese beer, because wild hops were found here in 1871, and the birthplace of asparagus growing in Japan.4567

Density About 165 people/km² at the 2020 Census and about 147/km² in August 2026 (calculated from the figures above)
Municipal history The town dates its founding to 1751, when an Ōmi merchant took over the Iwanai trading-post contract.3 Iwanai became a first-class town on 1 July 1900. On 1 April 1955 it merged with Shimano Village (島野村) to form the present town, which then had 26,242 people.3
Neighboring municipalities Kyowa (Iwanai District) and Rankoshi (Isoya District).8 Iwanai, Kyowa, Tomari and Kamoenai make up the Iwau (岩宇) area.8
Symbols Tree: Japanese rowan (ナナカマド). Flower: bush clover (ハギ). Both were chosen on 29 October 1980.314 Bird: none found. The town emblem dates from 16 February 1935. Its five outer rings read as "I-wa" (a pun on itsutsu no wa, "five rings"), and the shape inside is the character 内, so together they spell Iwanai.314
Mascot Taramaru (たら丸) is a walleye pollock with a twisted headband, black rubber boots and cod-roe lips. His birthday is 9 August 1985. He has a twin sister, Beniko (べに子, another word for cod roe), and a little brother, Pinsuke (ぴん助). A local clothing-shop owner designed him, and he was picked from many entries in a public contest.15

Name origin

The name comes from Ainu, but its meaning is disputed. The two main readings are iwaw nay (イワウナイ, "sulfur river") and iwa nay (イワナイ, "mountain river").8 The town tourism portal lists two more: iyau nay (イヤウ・ナイ, "stream where bear meat is dried") and ye-o-nay (イェ・オ・ナイ, "river with much pumice"). It also says Mt. Iwanai was probably named after the town.21 The name was fixed in its present form in 1869, when Ezo was renamed Hokkaido.3

History
  • Jōmon period. The Iwanai Higashiyama Entō-doki site (岩内東山円筒土器文化遺跡) dates from the Early to Middle Jōmon. It was a stopping point for the Entō pottery culture as it spread north from Tōhoku along the Sea of Japan coast. It is a Hokkaido historic site, and its finds are a Hokkaido tangible cultural property.228
  • Trading-post era. Japanese (Wajin) travel to the area is recorded from 1456.3 In 1751 Ebisuya (Okada) Yasaemon (恵美須屋岡田弥三右衛門), a merchant from Ōmi, took the trading-post contracts for Iwanai and Furuu (古宇). Iwanai counts this as its founding year. A stone in Manda marks the site of his unjōya (運上屋) trading house.323 Herring pound nets came into use around 1850–51. In 1857 a hot spring was found deep in the Raiden mountains; it later became Asahi Onsen.34
  • Meiji boom. The contract system ended in 1869, when a Kaitakushi (colonial office) branch opened. In 1871 the American geologist Thomas Antisell found wild hops here and urged the Kaitakushi to grow them. This was a step toward the brewery that became Sapporo Breweries.36 Herring fishing peaked from about 1897 to 1907. Iwanai became a first-class town in 1900 and had 15,560 people by 1902.3
  • Early 1900s. Iwanai Hydroelectric switched on Hokkaido's first hydroelectric lighting in 1906.324 On 4 May 1912 a storm wrecked more than 100 herring boats and killed 136 fishermen. The JNR Iwanai Line (14.9 km, from Kozawa) opened that November.325 In 1922 Dr. Shimoda Kikuzō planted asparagus here, the first in Hokkaido, and Japan Asparagus Co. (日本アスパラガス) was founded in 1924. From 1932 the herring disappeared.37
  • Great Iwanai Fire, 26 September 1954. The fire broke out during Typhoon No. 15, the storm that also sank the ferry Tōya Maru. It burned 3,298 homes (80% of the town) and killed 35 people. About 1,500 of Kida Kinjirō's paintings were lost. The town was rebuilt within about three years.3265 Minakami Tsutomu based the fire in his novel Kiga Kaikyō (飢餓海峡) on this one.8
  • Merger and after. Iwanai merged with Shimano Village on 1 April 1955. The Raiden area became part of the quasi-national park in 1963. Hot water was struck at the foot of Mt. Iwanai in 1974.3 The Iwanai Line closed in 1985. A ferry to Naoetsu ran from 1990 until it was suspended in 1999.38 The roadside station opened in 1993 and the Kida museum in 1994. Deep-sea water supply began in 2005.3
  • Recent years. The ski area passed to a private operator for the 2017–18 season and became IWANAI RESORT.27 The Iwanai Brewery opened in 2022, 150 years after the hop discovery.28 The restored Gansuien garden reopened in 2024.29 On 17–18 May 2026 the whole town was without tap water after the Horonai River, its water source, turned muddy.30

  • Location. Iwanai lies at about 42°59′N, 140°31′E, where the western side of the Shakotan Peninsula meets the land.

  • Coast and park. Southwest of the town, the Raiden coast is lined with cliffs and odd-shaped rocks. It lies within the Niseko-Shakotan-Otaru Kaigan Quasi-National Park (ニセコ積丹小樽海岸国定公園).83
  • Climate. The town calls itself one of Hokkaido's milder places, with fairly light winter snowfall. The yearly high is usually around 32°C, the yearly low around −13°C, and the average about 10°C.14 Town records for 2020 show a mean of 10.7°C, a high of 34.8°C and a low of −12.5°C.

By weight the largest catch was Atka mackerel (hokke, 833 t). The squid catch fell from 595 t in FY2018 to 167 t.
