What this place is

Ozegahara (尾瀬ヶ原) is a high altitude marshland in the Oze National Park, Japan. Approximately 8 km2 in size, the marshland is well known for various species of plants, including the "mizu-bashō" (White Skunk Cabbage), "Nikkōkisuge" (yellow alpine lilies, Hemerocallis dumortieri var. esculenta) and "Watasuge" (Eriophorum vaginatum). The marshland is a popular hiking destination.

Oze National Park (尾瀬) is one of the standout places to visit in Gunma. Give yourself unhurried time for photos, seasonal views, and nearby food stops. IC cards such as Suica, Pasmo, or ICOCA cover most trains and city buses.

Why it is worth the trip

  • A planting plan that guarantees something in bloom or colour in almost every month.
  • Paths, ponds and pavilions arranged so that the view reframes itself every few steps.
  • A local gathering place: morning walkers, picnic blankets, festival stalls and evening illumination.

What you can do here

  • Do a slow loop of the main path and stop at each designed viewpoint.
  • Bring a bento or grab something from a nearby konbini and picnic on the lawn.
  • Photograph the seasonal star — check the park's bloom calendar before you go.
  • Rent a bike where available; larger parks are far quicker to see on two wheels.
