Behold a miracle of nature, just ninety minutes from Tokyo

Koajiro Forest

In the spotlight as a ecotourism destination, Koajiro Forest is home to the only untouched natural ecosystem in the greater Tokyo area. From the verdant wood and riverhead to wetlands, mudflats, and the ocean, marvel at the otherworldly beauty of the Japanese landscape, unchanged since ancient times. The forest trails are well maintained to be easily walkable, and it's a perfect spot for picnics as well. Experience the awe and wonder of the natural world.

A firefly and wildflower sanctuary

The trail will take you through broad-leaved woods and valley groves where majestic oak and alder trees rise high. Emerge from the forest to find a wetland where reeds grow thick, a veritable treasure chest of animal and plant life. Due to devoted environmental conservation efforts in recent years, fireflies now often appear on summer nights, making for a positively dreamlike sight.

Creatures of the woods

Over two thousand species of flora and fauna—including many endangered species—call make their home in Koajiro Forest. Open your ears to the lilting calls of the Japanese bush warbler, the Japanese tit and other songbirds, and let the sound of the rushing brooks cleanse your soul. Look closely amidst the grass and, depending on the season, you'll see all sorts of insect life, from butterflies and dragonflies to grasshoppers.

The red-clawed crab, the honorary mascot of the forest

This is the red-clawed clab (akategani in Japanese). These little fellows are unique among their crab brethren, as they make their homes in the forest, rather than by rivers or the sea. When spring turns to summer, you can enjoy their delightful mating dance. Almost sixty species of crabs can be observed at Koajiro, including the endangered mudflat crab chiromantes dehaani.
