The video shows lush greenery of "The Water Conservation Forest"managed by the Tokyo Waterworks in the Tama River watershed area.
Arround 1901, the forest devastated. Tokyo Pref. at the time started the forest management for the stable water supply.
Approx. 120 years later... The vast forest is the source of the pure water that quenches Tokyo’s thirst. Why don’t you relax in the lush forest getting away from the hustle and bustle of a city?
