Yumura Onsen Araayu: Hot Spring Guide & Visitor Access

In Shin-onsen Town in the northwest of Hyogo, Yumura Onsen is a rustic mountain hot spring said to have been opened in 848, during the Heian period, by the priest Jikaku Daishi. Along the Harukigawa River that runs through the center of town bubbles the Araayu source, gushing out water at ninety-eight degrees, its rising steam a symbol of the village. The water is a sodium bicarbonate, chloride, and sulfate spring, and its source temperature is the highest in Japan.

Highlights

At Araayu, locals and visitors alike enjoy the simple pleasure of lowering eggs and vegetables into the source to boil them. The freshly cooked Araayu eggs are a taste unique to Yumura. A free public footbath called Fureai-no-yu sits along the river, where soaking your feet while watching the steam eases the fatigue of travel. Wandering the retro streets of the town is a pleasure in itself.

Enjoying the Seasons

Winter brings the prized snow crab of the San-in coast, and many come for both the baths and the crab. The steaming Araayu amid a snowy landscape is especially evocative. From spring through autumn, riverside walks are delightful, with greenery and fall colors framing the rustic village.

Access and Basic Information

By public transport, take the Shin-onsen town bus, the Yumetsubame, about twenty-five minutes from Hamasaka Station on the JR San-in Main Line, with a fare of around three hundred yen. By car, you can reach it via the Kitakinki Toyooka Expressway and connecting roads. The water is a sodium bicarbonate, chloride, and sulfate spring, and its source temperature of ninety-eight degrees is the highest in Japan. Araayu and the Fureai-no-yu footbath are free to enjoy, and day-use bathing facilities and inns dot the area.

Practical Travel Notes

The egg-boiling experience at Araayu photographs best in the morning or evening when the steam stands out most. The Fureai-no-yu footbath is a large one that can hold more than seventy people at once, handy for a rest between strolls. Allow about one to two hours for Araayu, the footbath, and a walk through the town. Nearby flows the Harukigawa River right beside Araayu, and going a little further brings spots with views of the Tajima countryside. Bus service is limited, so if you rely on public transport, check the outbound and return times in advance. Budget-wise, Araayu and the footbath are free, day-use bathing runs from a few hundred to a thousand-plus yen, and raw eggs for boiling can be bought cheaply at shops in the town.

A Quick Tip

If you want to boil eggs at Araayu, you can buy raw eggs at shops in the town. Posted guides show the recommended boiling time, so follow them for perfectly cooked hot spring eggs. Because the source is a scalding ninety-eight degrees, take care to avoid burns and follow the posted guidance for safe enjoyment.
