National Route 37 is an {{convert|81.1|km|mi|adj=mid|-long|sp=us}} highway in southwestern Hokkaido that runs east from Oshamambe to Muroran. Its eastern terminus lies at an intersection in central Oshamambe where it meets national routes 5 and 230. From there national routes 37 and 230 travel together paralleling the coastline of Uchiura Bay and the Dō-Ō Expressway. Along the way from Oshamambe to Muroran, it passes through the towns of Toyoura and Tōyako and the city of Date. National Route 230 leaves National Route 37 in Toyoura traveling north to Lake Tōya and Sapporo. Shortly after crossing in to Muroran, the route splits from the Hakuchō Shindō, a bypass of National Route 37 that crosses the Hakuchō Bridge to the tip of Cape Chikiu and central Muroran, while the main route continues to eastern Muroran.{{cite web|title=白鳥新道計画路線図|trans-title=Hakuchō Shindō Plan Route Map|url=http://www.city.muroran.lg.jp/main/org7310/documents/2kirosen.jpg|publisher=City of Muroran|language=ja|date=21 February 2014|access-date=1 October 2020|archive-date=23 September 2015|archive-url=https://web.archive.org/web/20150923204322/http://www.city.muroran.lg.jp/main/org7310/documents/2kirosen.jpg|url-status=dead}} National Route 37's eastern terminus in eastern Muroran is at an intersection where it meets National Route 36.{{cite web|title=占用制限を行う路線一覧（一般国道）|trans-title=List of routes that restrict private use (general national highways)|url=https://www.hkd.mlit.go.jp/ky/kn/kengyou/u23dsn00000018w0-att/u23dsn00000018z4.pdf|work=Hokkaido Development Bureau|language=ja|date=12 July 2019|access-date=1 October 2020}}
History
On 4 December 1952 the route was designated as Primary National Highway 37 between Oshamambe and Muroran.{{cite web|title=一級国道の路線を指定する政令|trans-title=Cabinet Order designating the Primary National Highways|url=https://ja.wikisource.org/wiki/%E4%B8%80%E7%B4%9A%E5%9B%BD%E9%81%93%E3%81%AE%E8%B7%AF%E7%B7%9A%E3%82%92%E6%8C%87%E5%AE%9A%E3%81%99%E3%82%8B%E6%94%BF%E4%BB%A4|language=ja|date=4 December 1952|access-date=1 October 2020}} On 1 April 1965 the highway's designation was revised along with the other primary routes as General National Highway 37.{{cite web|title=【国道トリビア】 国道の番号に欠番があるのはなぜ？|trans-title=National Highway Trivia.
