What makes it special
Look at a spring rising in the middle of the river, bathe in a public bath named for the one where a shogun was murdered, and walk through bamboo to the temple. Izu's oldest hot spring is a history book you read on foot.
Why?
The tourism association calls Shuzenji 'the oldest hot-spring resort in Izu'; Tokko-no-yu is the founding spring, now off-limits for bathing, and Hakoyu (700 yen) is the only public bath. Per Wikipedia, shogun Minamoto no Yoriie was confined at Shuzenji temple and assassinated, and Hakoyu opened in 2002. Chikurin-no-komichi is the bamboo path along the Katsura River.[2][3][4]

About the water
According to Wikipedia the water is an alkaline simple spring at 65 °C, pumped at 600–700 litres a minute. As a low-mineral simple spring it is gentle, and the association leads with history rather than chemistry, calling it 'Izu's oldest resort'. Seven riverside public baths once stood here; only Hakoyu remains, and Tokko-no-yu is for viewing. Two free foot baths, Kawarayu (six seats) and River Terrace Sugi-no-yu (ten), sit by the water. pH and analysis sheets could not be read on official pages.

Three things not to miss
Photo information
Tokko-no-yu
Mid-river in the Katsura, at the heart of town The founding spring of Shuzenji, said to have burst out when the monk Kobo Daishi struck the rock with his tokko, a ritual implement. Today it is for viewing only, no bathing; it was moved slightly in 2009.
Hot water rising from a riverbed, the most elemental image of an onsen, sits right in the middle of town. It is also the last trace of the seven riverside baths that once lined the Katsura.[3][2][4]

Hakoyu public bath
A few steps from Tokko-no-yu A public bath opened in 2002: 700 yen adults, 400 children (350 for Izu residents). 10:00–21:00 (last entry 20:30), irregular closures, opens at 15:00 on the second Thursday.
It carries the name of the bath where Minamoto no Yoriie, second Kamakura shogun, is said to have been attacked. It stands a few steps from Tokko-no-yu.[2][4]

The bamboo path and Shuzenji temple
Along the Katsura River between the bridges, and the temple at the centre A bamboo-lined walkway along the river, lit at night. Shuzenji temple was founded in 807 by Kobo Daishi (Kukai), according to the temple; the office is open 8:30–16:30 and entry to the grounds is free. The treasure hall opens 8:30–16:00 (to 16:30 April–September).
Hie Shrine next door, and across the river Shigetsuden (built by Hojo Masako for her murdered son Yoriie, the oldest wooden building in Izu) and the graves of Yoriie and Noriyori, are all within an easy walk.[3][5][4]
The story
From rock struck with a tokko
Legend says that in the Heian period the monk Kobo Daishi (Kukai) struck a rock in the Katsura River with his tokko, a ritual implement, and hot water gushed out. That is Tokko-no-yu, the origin of Shuzenji Onsen. The temple dates its own founding by the saint to 807, and the tourism association calls Shuzenji 'the oldest hot-spring resort in Izu'. Seven public baths once lined the riverbank; Tokko-no-yu is the only survivor, now protected, moved slightly in 2009 and closed to bathers.[4][5][2][3]
The bath where a shogun died
Minamoto no Yoriie, second shogun of the Kamakura government, was confined at Shuzenji temple by his mother Hojo Masako and her clan and assassinated there aged 23. The public bath Hakoyu (700 yen), built in 2002, takes its name from the bath where he is said to have been attacked. Shigetsuden, which Masako built for his soul, is the oldest wooden building in Izu and holds his grave. Yoritomo's brother Noriyori was also confined here and, the story goes, took his own life when Kajiwara Kagetoki's men attacked; his grave remains too. Kido Okamoto's play 'Shuzenji Monogatari' is built on Yoriie's tragedy.[4][3][2]
Soseki's illness and a town of writers
The novelist Natsume Soseki, convalescing at Shuzenji, took a grave turn and fell briefly into a coma. The 'Shuzenji crisis' shadows his later work. Akutagawa Ryunosuke, Ozaki Koyo, Izumi Kyoka and Kawabata Yasunari also wrote here. With the bamboo path along the Katsura, the Katsura and Kaede bridges and its teahouses, the town is built to be read at walking pace.[4][3]
One train from Mishima, ten minutes by bus
From Mishima on the Shinkansen, the Izuhakone Railway runs about 32 minutes to its terminus at Shuzenji Station; a Tokai bus marked 'Shuzenji Onsen' takes about 10 minutes (200 yen) and drops you within a few minutes' walk of Tokko-no-yu, Hakoyu and the temple. On 20–21 August the autumn Kobo memorial brings a lantern procession and some 2,000 fireworks; autumn colour peaks from mid-November to early December. The Kawarayu and River Terrace foot baths are free.[6][7][8][2][9]
