Aichi

Aichi has 35 onsen areas and 133 springs (Ministry of the Environment, FY2024), with about 1.45 million overnight stays a year. There are no volcanoes; the main bathing areas are the seaside resorts of Gamagori on Mikawa Bay and Yuya in a gorge in the Okumikawa hills. Miya in Gamagori is just over 40 minutes from Nagoya on the JR Tokaido Line.

Main onsen areas

Along Mikawa Bay, Gamagori has Miya, Nishiura and Katahara, and the coast continues with Kira in Nishio and the Minamichita group at the tip of the Chita Peninsula. In the Okumikawa hills are Yuya in Shinshiro, Shiotsu in Shitara and Yu-Land Paru Toyone in Toyone. Inuyama sits on the Kiso River.

Characteristic spring types

Simple and chloride springs make up most of our records. Yuya is a chloride spring rising beside the river, Miya in Gamagori is also chloride, and Katahara is a smooth alkaline simple spring. Most sources are below 42 °C.

Reachable by public transport

Miya's nearest station is Mikawa-Miya on the JR Tokaido Line, just over 40 minutes from Nagoya; from there, use your inn's shuttle or the community bus that runs three days a week. Nishiura is reached by Meitetsu bus from JR Gamagori Station, or by inn shuttle from Nishiura Station on the Meitetsu Gamagori Line. At Yuya, inns line the street from Yuya-Onsen Station on the JR Iida Line, where the Inaji limited express from Toyohashi stops.

For solo travellers

Yuya is a small resort with inns starting at the station, easy to get around without a car.

Food & culture

Minamichita whitebait, Nishio matcha and Nagoya's local dishes add flavour to an onsen trip. Yuya is said to have been found some 1,300 years ago by a hermit sage of Mt Horaiji and has long been linked with pilgrimages to Mt Horaiji. In Inuyama you can watch cormorant fishing on the Kiso River and visit Inuyama Castle, a National Treasure.
