Kanna, Gunma

Footprints pressed into Cretaceous mud — exposed now beside Route 299, behind a parking area with a small souvenir shop and a lunch counter — are what Kanna-machi is organized around. The 瀬林の漣痕, ripple marks left by an ancient shoreline, were uncovered during road construction in 1953, and the town has been quietly rearranging itself around that discovery ever since. The 神流町恐竜センター opened decades later and now holds both local fossil specimens and dinosaurs excavated in Mongolia, alongside hands-on fossil digging sessions that draw school groups on weekday mornings.

The geography presses in on all sides. Kanna sits within a mountain graben, its geology layered and complex, limestone quarried here by Chichibu Taiheiyo Cement. That same limestone shapes the waterfalls: 白水の滝 seeps through moss-covered rock beside an active mining road, a quiet, diffuse curtain of water rather than a single drop. Further into the hills, 早滝 along the Shiozawa River and 小豆の滝 at high elevation freeze solid in winter, their surfaces turning opaque and ridged.

The 道の駅万葉の里 on Route 462 functions as a practical hinge — shop, canteen, information — and the 恐竜王国秋祭り gives the town a moment of collective noise each year. Outside that, the pace is unhurried. Fossil replica souvenirs sit in shop windows alongside the ordinary merchandise of a mountain town, and 赤久縄山 rises at the edge of everything, accessible by forestry road, rarely crowded.
