What makes it special
A town that shares more than 26,000 litres a minute, the biggest flow in Shizuoka, between a three-storey wooden inn of 1928 and public baths named for the Seven Lucky Gods.
Why?
The Ito tourism association posts 26,836 litres a minute (January 2024), the largest in Shizuoka Prefecture. Tokaikan is a three-storey wooden former inn built in 1928, open for day bathing at weekends and holidays. The town's public baths carry the names of the Seven Lucky Gods; Wada Jurojin-no-yu costs 400 yen.[2][3][4][5]

About the water
The association posts 26,836 litres a minute (January 2024), the largest flow in Shizuoka and among the biggest in Japan; Wikipedia gives 780 sources and 34,000 litres a minute, behind only Beppu and Yufuin, so the figures depend on the date. The water is mainly simple and weakly saline spring, colourless and odourless, and the association describes it as gentle on the skin. The Bishamonten Shiba-no-yu bath runs a 56 °C simple spring, diluted, as free-flowing water. The association mentions that chloride water holds heat; we do not treat that as a medical claim.

Three things not to miss
Photo information
Tokaikan
On the Matsukawa River, 7 minutes' walk from Ito Station A wooden three-storey inn from 1928, now open as a heritage building: 200 yen adults / 100 children (300 / 150 from fiscal 2026), 9:00–21:00 (last entry 20:00), closed the third Tuesday and 1 January. Day bathing on weekends and holidays only, 11:00–19:00, 500 yen adults / 300 children, with the large and small baths alternating between men and women.
One of very few places where you can walk through a pre-war hot-spring inn, and bathe in it, without staying. The top floor looks over the river and town.[3][4]

The Seven Lucky Gods baths
Around the town centre, 10–20 minutes' walk from the station Wada Jurojin-no-yu (400 yen, 14:30–22:30, closed Wed), Bishamonten Shiba-no-yu (400 yen, 14:00–22:00, closed Tue, simple spring at 56 °C), Oka Hotei-no-yu (450 yen, 14:00–22:00, closed Sun and 4th Sat), Ebisu Arai-no-yu (13:00–22:00, closed Mon) and more. Per Wikipedia there are ten neighbourhood baths, eight with a Lucky God statue, and a stamp rally.
Wada Jurojin-no-yu is the oldest of the group and once sent its water to the third shogun, Tokugawa Iemitsu. These are afternoon-opening neighbourhood baths that visitors use at the same price as locals.[5][6][7][8][9]
The Anjin Festival and the first Western-style ship
Around the Matsukawa estuary and Ito port The English navigator William Adams (Miura Anjin), on Tokugawa Ieyasu's orders, built an 80-ton Western-style ship here in 1604 and the 120-ton San Buena Ventura in 1607 at the mouth of the Matsukawa. The Anjin Festival commemorating this runs every 8–10 August; the 2026 edition marks its 80th year with 20,000 fireworks planned.
A hot-spring town that was also the birthplace of Japan's first Western-style sailing ship; spring, harbour and fireworks share the same river mouth.[10][11]
The story
Water for the shogun
Ito's spring is said to have been discovered in the Heian period, and in the Edo period its water was sent to the third shogun, Tokugawa Iemitsu, for his cure. The Wada Jurojin-no-yu neighbourhood bath, oldest of the Seven Lucky Gods baths, preserves that story. From the Meiji era writers such as Koda Rohan and Kawabata Yasunari came, and after the war Ito grew into a lively resort. Today the association posts a flow of 26,836 litres a minute (January 2024), the largest in Shizuoka.[12][5][2]
Anjin's ship at the river mouth
William Adams, an English navigator who came ashore at Usuki in Kyushu, won the trust of Tokugawa Ieyasu and the name 'Anjin', pilot. On Ieyasu's orders he built an 80-ton Western-style ship in 1604 and the 120-ton San Buena Ventura in 1607 at the mouth of the Matsukawa in Ito, using a 'sand dock' dug into the sandbar and floored with logs. These were Japan's first Western-style sailing ships, and the larger one later sailed to Mexico. The Anjin Festival is held every 8–10 August and reaches its 80th edition in 2026.[10][11]
Three wooden storeys from 1928
Tokaikan on the Matsukawa River is a three-storey wooden inn built in 1928, preserved as a city cultural property and opened as a heritage attraction: 200 yen (300 from fiscal 2026), 9:00 to 21:00. On weekends and holidays its baths open to day visitors from 11:00 to 19:00 (500 yen), the large and small bathrooms switching between men and women through the day. Few pre-war inns anywhere can be both walked through and bathed in.[4][3][12]
Baths that open in the afternoon
Ito has ten neighbourhood baths (Wikipedia), eight of them named for and marked by a statue of one of the Seven Lucky Gods, with a stamp rally to link them. Wada Jurojin-no-yu is 400 yen, 14:30–22:30 (closed Wed); Bishamonten Shiba-no-yu 400 yen, 14:00–22:00 (closed Tue); Oka Hotei-no-yu 450 yen, 14:00–22:00 (closed Sun and 4th Sat); Ebisu Arai-no-yu 13:00–22:00 (closed Mon). All open in the afternoon, so the day runs Tokaikan or the foot bath first, public baths later. Everything is 10–20 minutes' walk from the station on flat ground.[12][5][6][7][8]
