What makes it special
Springs at 98°C rise at 26 points around town, and steam drifts up all over this gorge-side spa.
The Tsuetate Onsen Tourism Association says the springs gush out at about 98°C from 26 points in town, and that the steam that defines the townscape comes from this scalding water.[1]
Facilities come from the register (Wikipedia, OpenStreetMap, official sites). Those marked "natural spring unconfirmed" are listed on the basis of their name only.
From JR Hita Station on the Kyudai Line, take the Hita Bus bound for Tsuetate (about 50 min; about 2 hr 10 min from Hakata via Hita). Highway buses for Kurokawa Onsen from Fukuoka Airport and Hakata stop here (about 2 hr 30 min). From Kumamoto, change at Aso Station to a Sanko bus (about 3 hr 10 min).
Clear, colourless, mildly salty water that comes out at 98–100°C. The tourism association describes it as gentle on the skin and rich in metasilicic acid, often called a natural moisturiser. It is far too hot to bathe in as it comes, so the shared and private baths cool it with added water.
Rheumatism, skin conditions, neuralgia, muscle and joint pain, frozen shoulder, motor paralysis, joint stiffness, bruises, sprains, chronic digestive complaints, haemorrhoids, sensitivity to cold, convalescence, fatigue, general health, cuts, burns, obesity, skin beautification (as listed by the tourism association)

Over the Tsuetate River in the middle of town Every year from late March to late April (except Golden Week) carp streamers hang from ropes strung across the river. It began, they say, by throwing a ball tied to a rope across to the other bank.
The tourism association calls Tsuetate the birthplace of the carp streamer festivals now seen all over Japan.[3]
Around town and in many inns At the town's shared mushiba you can steam eggs, sweet potatoes and vegetables in natural spring vapour. Many inns have mushi-yu, a kind of natural steam sauna; styles vary from cave-like rooms to boxes you sit in with only your head outside.
Locals say 'catch a cold, go to the steam bath first': steam is part of everyday life here.[1][2][10]
One lane back from the riverside street Sedoya is a maze of alleys created by decades of piecemeal building during the town's Showa-era heyday. At shared baths such as Yakushi-yu and Gozen-yu you drop ¥200 in the box. Motoyu, a half-open rock bath by Momiji Bridge, is free.
Old photographs hang along the alleys, and simply wandering between baths is the pleasure.[2][4][5]
According to the tourism association, Tsuetate's story goes back more than 1,800 years: Empress Jingu is said to have used water from a sacred spring up this river to bathe her newborn, the future Emperor Ojin. The name, 'standing staff', comes from a tale that Kobo Daishi visited in the early Heian period, planted his bamboo staff, and watched it sprout leaves.[2]
Guests once stayed a week or two for toji, long-stay therapeutic bathing, and in the early Showa era the town boomed as an entertainment quarter known as Kyushu's hideaway. Endless extensions from those days created the maze-like Sedoya alleys, and inns geared to long stays still remain.[2][1]
The tourism association credits Shiraiwa Onsen as the birthplace of the kazoku-buro, the private family bath rented by the hour. Around 1996 it obtained a new kind of bathing licence, setting off the private-bath boom that spread across Kyushu.[7]
