Her song "Natsu no Omoide" -- Summer Memories -- opens with an image of white skunk cabbage blooming in a misty highland marsh, and its melody became so deeply woven into the national consciousness that generations of schoolchildren have sung it without ever setting foot in the place that inspired it. That place is Oze, a basin of wetlands and volcanic peaks straddling four prefectures in northern Honshu, where boardwalks thread through bogs older than recorded history and the fight to keep it wild helped launch Japan's modern conservation movement.

Oze National Park: Walking Through the Song

Mon, 16 Feb 2026 00:00:00 GMT

The marsh boardwalks themselves are flat and gentle, but accessing them means mountain hiking with real elevation changes -- a round trip of six to eight hours from trailheads like Hatomachi Pass. This is deliberate. There are no roads into the...
