Hakone Onsen
onsen
Hakone Onsen, or Hakone Hot Springs, is a general term for numerous thermal spas located in the town of Hakone, Ashigarashimo District, Kanagawa Prefecture, Japan, an area formerly known as Sagami Province. Situated about 90 kilometres (56 mi) southwest of Tokyo and 60 kilometres (37 mi) east-southeast of Mt. Fuji, it is one of the most popular hot spring resorts in central Japan. At least twenty hot spring spring resorts exist around Mt. Hakone, an area that is designated as part of the Fuji Hakone Izu National Park.
History
The first hot spring in this area was reputedly opened in 738 during the Nara period by a wandering Buddhist priest and it is still used today. Hakone Onsen became famous after the warlord Toyotomi Hideyoshi conquered Odawara. He gathered samurai from many parts of the country to attack Odawara Castle, and after the battle rested in a hot spring there.
During the Tokugawa shogunate, tributary hot water from Hakone was regularly presented to the shogun in Edo (Tokyo). The area prospered as a way station along the Tōkaidō Road.
