Hakone Shrine is a Shinto shrine located in Hakone Town, Kanagawa Prefecture, at the foot of Mt. Hakone along the shores of Lake Ashi. The shrine itself lies hidden in a dense forest, but its large red "floating" shrine gates (Torii of Peace) stand prominently in the lake.

From chronicles stretching back as far as the Nara Period (710-794), Hakone has been named as a spot sacred to the mountain-worshiping religion. The original shrine was founded during the reign of Emperor Koushou (475 BC – 393 BC) on Mt. Komagatake. Holy Priest Mangan revived and relocated the shrine to Lake Ashi in 757. It was separated into three parts dedicated to the deities whom legends says appeared to him in a dream as a Buddhist acolyte, government official and woman and asked him to deliver the grace of the Buddhist and Shinto religions onto mankind.

In the year 801, before general and shogun Sakanoue no Tamuramaro set out on an expedition to quell the Northeast by imperial command, he left an arrow as offering in front of a cedar tree at Hakone Shrine as a prayer for his victory. The tree become known as the Yatate Cedar, or 'Standing Arrow Cedar,' and in later years other legendary generals such as Minamoto no Yoshiie, shogun Minamoto no Yoritomo, and Minamoto no Yoshitsune all left arrows as offerings there.

The shrine was destroyed by fire in Toyotomi Hideyoshi's Siege of Odawara and rebuilt by Tokugawa Ieyasu.
