What makes it special

Five minutes from the airport, at the end of the tram line: a spring of 4,861 litres a minute in the middle of a working port city.
Why?

The inn cooperative calls Yunokawa 'the hot-spring town closest to an airport in Japan': 5 minutes by car from Hakodate Airport and 31 minutes by tram from Hakodate Station. Its chloride springs yield 4,861 litres a minute at around 65°C.[2][1]

About the water

Yunokawa's water is a chloride spring close to the sea, neutral and roughly as salty as body fluid (isotonic). There are two strands: a clear 'shirayu' and a reddish 'akayu', and inns draw one or both. The flow is a generous 4,861 litres a minute, and many of the inns that take day visitors advertise free-flowing source water. Salt springs are said to keep you warm after bathing, though that is a tradition rather than a guarantee.

Proof that Yunokawa's water is not just for humans.[3][1]

03

Yukura Shrine, birthplace of the spring

2-28-1 Yukawa-cho Where Yunokawa began: a woodcutter is said to have healed his wounds here in 1453, and in 1653 a young lord of the Matsumae clan recovered after bathing and dedicated a Buddhist statue in thanks. A stone marks the spring's birthplace.

A 570-year-old memory of healing baths kept alive at a city shrine.[1][3]

The story

A woodcutter and a young lord

Yunokawa's story begins in 1453, when a woodcutter is recorded healing his injuries in the spring. In 1653 the young Matsumae lord Senkatsumaru, later Matsumae Takahiro, recovered from a serious illness after bathing here and dedicated a Buddhist statue and a temple gong in thanks. A stone at Yukura Shrine marks the birthplace of the spring.[1]

From horse tram to streetcar

In 1885 Ishikawa Tosuke struck a hot, abundant source, and a newspaper advertisement the next year announced the opening of the baths. A horse-drawn tramway reached Yukawa in 1898 and was electrified in 1913, linking the resort to the city centre in 30 minutes; Japan's first road reserved for motor cars opened here in 1918. That same streetcar still runs from Hakodate Station to Yunokawa today.[1]

The spa nearest an airport

Five minutes from Hakodate Airport, the inn cooperative bills Yunokawa as the hot-spring town closest to an airport in Japan. The Emperor and Empress stayed at the Wakamatsu inn in 1954, and in 1976 Hokkaido designated the area a protected hot-spring zone. Large seafront hotels stand beside old inns, and at the post-Bon fireworks festival the inns still offer spring water to Yukura Shrine.[1][2][6]

Editors' guide

Take the tram from Hakodate Station to the end of the line. Try the salty water in the footbath by the stop, see the birthplace stone at Yukura Shrine, then bathe at KKR Hakodate (11:00–21:00) or Hotel Tetora (13:00–22:00). Tram back for the night view from Mt Hakodate, morning market the next day. With the airport five minutes away, it makes a good last stop.
