Todoroki Ravine Japanese Garden was built on a slope, with rocks and boulders providing the contours and shapes. Unlike the usual fussy manicured parks and Zen gardens, this gorge is wild and untamed with a jungle atmosphere - home to birds and other animals. Todoroki is only minutes from central Tokyo, but is a world away from the city with bamboo, trees, shrines and the sounds of the river to wash away urban sounds. The ravine was formed by the Yazawa River as it heads for theTama River, it is the only ravine and valley in Tokyo stretching along a one-kilometer course along a path viewing waterfalls along the way. Todoroki Valley also has a natural water spring and is more of an adventure stroll than a typical Japanese garden, despite its name.
