A walking course to enjoy the iconic scenery of Kuju and the changes of the four seasons.

Course Outline

Visitors can bask in the nature of Kuju by following the Yamanami Highway to tour the Tadewara Marsh that spreads across Chojabaru and the surrounding forests.

Wooden paths run through the marsh, with some portions accessible by wheelchair, allowing visitors to choose a route that suits their preference.

Although the forests surrounding Tadewara Marsh are not wheelchair-accessible, there are virtually no ups and downs along the paths that lead visitors through sun-dappled groves of Japanese oak, Japanese beech, and other deciduous broad-leaved forest. Visitors can stroll through forests that are rich in variety, including areas covered by sphagnum moss.

Visitors stopping by the Chojabaru Visitor Center before or after a stroll can further enhance their walking experience by obtaining up-to-date information on flowers and life forms and learning more about the nature of the Kuju region.

Fire that protects the marshland, and sprouting Viola orientalis

The grassland burning that is performed every year from March to April burns away dead flowers and prevents forestation. This helps maintain the grassland scenery of Tadewara Marsh. In spring, Tadewara Marsh turns into a sea of black. Plants begin sending up shoots and change day-by-day, presenting visitors with flowers in every color. Among these, the yellow blooms of the Viola orientalis contrasted against the black color of the land are a sight to behold.

Of the many flowers appearing on the grassland in August and September, Echinops setifer is incredibly unique in appearance. It is a plant that originated on the Asian continent, which was connected to Japan by a land bridge during the Ice Age. At the ends of the plant's notably long stalks, flowers bloom like balls of vivid lapis lazuli. A closer look at the latter reveals that what appears to be a single ball is actually a collection of tiny flowers.
