In the Edo period, Gero Onsen was referred to as one of Japan's three best onsen by the Confucian poet Hayashi Razan. While the town may now be quite a bit more urbanized than back then, the waters have retained that special quality which has made them so famous.

Interestingly, the name Gero (lit. "lower bath") is pronounced the same as the slang term for "vomit". This has not hurt its popularity among Japanese tourists, however, with more than one million visitors every year, who continue to rate it as one of the best hot spring resorts in Japan.

Gero is located between Nagoya and Takayama, about an hour south of Takayama. This makes it a convenient stopover, or an attractive alternative to stay during the Takayama Festival, when lodging is difficult to find in Takayama.

Onsen (hot springs) are what make Gero famous, and there are three public bath houses available in town. Also at the south end of the Gero Bridge is a large rotenburo (open-air bath) you can bath in for free; however, it has no facilities and is exposed to the bridge above.

There are also many baths located in the numerous ryokan in the Gero area, several of which are open to the public during certain times of the day.

A good way to sample some of these is to purchase a Yumeguri Tegata (spa pass), a wooden tablet that can be bought all around Gero including the tourist office, ryokan, souvenir shops and convenience stores.

The Yumeguri Tegata gets you three visits to the baths of any of about thirty participating ryokan. It costs 1200 yen and is good for six months. It also makes a great souvenir.

Also dotted around the city are free footbaths where one can sit and relax after a hard day of walking.

Onsenji Temple worships Yakushi Nyorai, the Buddha of healing, whose image is credited to restoring the flow of hot spring water to the town after it was stopped up by a large earthquake. Climb the stone staircase to the temple gate to get a view of the city and Hida River.

Located just above town is the Gassho Village (Gero Onsen Gassho Mura), an open air museum of gasshozukuri farmhouses, traditional steep roofed houses from the Shirakawago region. Here you can view the houses, see performances, or participate in traditional folk art. Also inside the Gassho Village complex is a komainu (shrine guard dog statue) museum.
