Yumura Onsen
A hot spring town in far northern Hyogo built around Arayu, an open 98°C source pool in the street where residents and visitors boil eggs and vegetables. A free foot bath runs along the river beside it.

Most onsen towns hide their source. Yumura puts it in the middle of the street. Arayu is an open pool of spring water at 98°C beside the Haruki River, steaming continuously, roped off but entirely public — and the town uses it. Visitors buy a net bag of eggs, sweet potatoes or corn from a nearby shop, lower it into the pool on a hook and stand around waiting for it, which is the town's main social activity. The river beside it has a long free foot bath cut into the bank. Around this core sits a small, low-rise spa town of the kind that was common in northern Hyogo and is now rare: stone bridges, willow trees, a statue commemorating an early-1980s NHK drama set here that made the town famous across Japan. It is close enough to the Sea of Japan coast that crab is the winter reason to come.
Why it stays quiet
It is a household name in western Japan thanks to the drama, but it sits in the far north of Hyogo, four hours from Osaka by limited express and local bus, with very little English information available.
Background & history
Local tradition dates the spring to 848 and credits its opening to the Tendai priest Ennin, known posthumously as Jikaku Daishi. The town's modern fame came much later: an NHK television drama set in Yumura and broadcast in the early 1980s put it in front of a national audience, and the town still marks the connection with a statue and with signage along the river.
What to look for — in walking order

- Arayu source pool
- an open 98°C spring in the middle of town, steaming beside the Haruki River
- Boiling your own eggs
- buy a net bag from a nearby shop, hook it into the pool and wait
- The riverside foot bath
- a long free foot bath cut into the bank of the Haruki River
- The old spa-town streets
- stone bridges, willows and the statue marking the drama filmed here
How to enjoy it
Come in winter if you can. The steam off Arayu is at its most dramatic in cold air, and this is snow crab season on the coast 25 minutes away, which is what most Japanese visitors are actually here for. Buy the egg net first — the wait beside the pool is where you end up talking to people.
How to actually get there
- Osaka Stn → Hamasaka Stn (JR Hamakaze limited express, ~3 hr 20 min, few services a day).
- Hamasaka Stn → Yumura Onsen (Zentan Bus, ~25 min, roughly hourly).
- From the bus stop, walk to Arayu and the Haruki River foot bath — both are in the town centre.
- JR Hamakaze limited express + Zentan Bus
- Osaka Stn →(JR Hamakaze limited express, ~3 hr 20 min)→ Hamasaka Stn →(Zentan Bus toward Yumura Onsen, ~25 min)→ Yumura Onsen. Total about 4 hours. The Hamakaze runs only a few times a day, so reserve a seat and check the day's departures.
- Bus to Hamasaka, then the Hamakaze back
- Zentan buses run roughly hourly back to Hamasaka Station, but the Hamakaze services to Osaka are few and the last useful one leaves in the afternoon. Confirm the return train time before you decide how long to stay. An express bus also runs direct from Yumura Onsen to Osaka and Kobe, which is often the easier return.
Before you go
- Cash
- The local bus takes cash and IC cards. Egg nets, foot-bath towels and small shops around Arayu are cash. There is no reliable foreign-card ATM in the town.
- Closing days
- Arayu is a live 98°C spring, not an attraction with a barrier you can lean on. Keep back from the edge, use the hooks provided, and keep children well away.
- Another way
- The Sea of Japan coast at Hamasaka is 25 minutes back down the bus route; in winter this stretch is one of Japan's main snow crab ports.
- After you get off
- The bus stops in the centre of the town, a couple of minutes from Arayu and the riverside foot bath.
