Ichino-yu, Public bathhouse in Iga, Mie Prefecture, Japan

Ichino-yu is a public bathhouse in Ueno, Iga, Mie Prefecture, entered through a granite gate with iron doors and a curved karahafu roof. The main building, erected in 1926, is Japanese in style but its bath entrance walls carry terracotta and arched Western elements. The second floor, once a rest area, is no longer used.

Ichino-yu opened in 1950, when its founder bought an existing bathhouse called Kusatsu-yu and renamed it, using leftover building materials and sawdust from his construction business. The stone-pillar gate and the karahafu-roofed main building, however, date from 1926 (Taisho 15). In June 2013 both were registered as a Registered Tangible Cultural Property of Japan. In July 2023 the Kyoto bathhouse-succession company Yutonamisha took over operations.

The bath's name appears in a neon sign above the granite gate, installed when the business opened in 1950. Inside, the third-generation owner since 2008 removed the television, switched to warm bulb lighting and plays Showa-era popular songs. Goods sold near the bandai counter focus on health items and traditional Japanese small crafts, proposing a "Japanese way of living".

Ichino-yu is a five-minute walk from Kayamachi Station on the Iga Railway, or about ten minutes from Uenoshi Station; buses from Nagoya, Kyoto and Osaka stop at Ginza Yonchome, two minutes away. There is free parking for up to 40 cars, 26 of them with a one-hour free ticket. The bath is closed on Thursdays.

The bathhouse was opened in 1950 by a construction businessman who used leftover building materials and sawdust from his trade. The neon sign reading "Ichino-yu" above the granite gate with its Western-style iron doors dates from the opening and remains the bathhouse's symbol.
