Facts & Figures

Lake Okutama (Okutama-ko) is an important water reservoir for the city Tokyo. More than 20 percent of the needed water for the capital comes from this place. This artifical lake was created through the Ogouchi Dam (height 149m, length 353m) and covers an area of 263.8 square kilometre. Okutama-ko is part of the Chichibu-Tama-Kai National Park. I recommend you to explore this easily accessible area around Lake Okutama during a day trip from Tokyo. It takes just 2hrs to get there from downtown Tokyo. You can do fishing, hiking, camping, swimming, canoeing, forest bathing (Shinrin-yoku), soaking in hot water and you should enjoy every minute of this amazing place.

History

It took 20 years till 1957 to finish the construction of the Ogouchi Dam. 87 people died during the construction phase. To get more information about the damn and region visit the Okutama Mizu to Midori no Fureai-kan museum at the lake Okutama.
