Kamisunagawa, Hokkaido

The valley narrows as you follow the course of the Panke Utashinai River northward, the forested slopes of the Yūbari mountain range pressing in on both sides. The town of Kamisunagawa sits along this river corridor, its streets arranged in the long, linear pattern common to settlements that grew around a single industry. That industry was coal — specifically the seams of the Kamisunagawa coalfield, which drew workers and capital into these hills for most of the twentieth century, and whose closure in the late 1980s left the town reconfiguring itself quietly around what remained.

What remained is visible in the repurposed structures that now house the Kamisunagawa Tankōkan and its attached science museum, where the physics of weightlessness — an unlikely pairing with underground mining — is explored in a building that once served the coal operation. The Mitsui Sunagawa mine, which ran through this ground for decades, also left behind a record of danger: gas explosions and underground fires punctuate the town's history at intervals, each one a reminder of what the work actually cost. Walking past the old infrastructure, the scale of what was once here is readable in the bones of the place.

The town now produces cheese and shiitake mushrooms, and the hot spring facility Panke no Yu offers a bath fed by local waters. These are modest anchors for daily life, not spectacles. The branch rail line that once connected Kamisunagawa to Sunagawa city was discontinued in the mid-1990s, and the road now carries what the train once did. The Japanese garden in town sits without fanfare, another layer added over the years to a place still finding its shape after the coal ran out.
