Getting there
Reaching the trailhead for the hike couldn’t be easier. On weekends, you can catch the Holiday Rapid Okutama, a special train that runs on the Chuo Line. This train will take you directly from Shinjuku Station to Okutama Station, the end of the line, without having to make any transfers. From there, look for the Okutama Historical Road (Okutama Mukashi-Michi). If you have trouble finding the starting point, you can always ask the staff at Okutama Station.

Initially, traveling along Okutama Mukashi-Michi is a relatively casual affair. Portions of the route are paved and you’ll even pass through a quaint neighborhood. Eventually the pavement and neighborhoods fade away into a proper hiking trail, and before you know it, you’ll be trekking through a forest filled with vibrant green, golden, and crimson hues.
Ascending to Ogochi Dam
As you continue along the 10-kilometer trail, you’ll start to gain altitude and catch glimpses of your goal: the historic Ogochi Dam, the only thing separating you from Lake Okutama and its captivating surroundings. As you reach the summit and the home stretch of the trail, navigation can get a little tricky. However, there’s no need to worry—at this point the lake will be in view, and that will always keep you moving in the right general direction.
Plenty to do
Once you reach the end of the trail, your first order of business should be to swing by the Okutama Water and Green Friendship Hall (basically a visitor center and science museum) to take a break, stock up on supplies, and perhaps buy some lunch (unless you packed a bento). It’s also a good idea to check the bus schedule and plan your return trip to the station. (Or, if you have the energy for it, you can hike back the way you came whenever you please.)
Seasoned hikers may wish to continue hiking along the lake and in the surrounding foothills. If you’re lucky you may even see some monkeys!
For those fascinated with engineering and infrastructure, feel free to explore Ogochi Dam. You can go inside various sections and learn how Lake Okutama, which is technically still part of Tokyo, provides the city with fresh drinking water.

Alternatively, if you’re worn out from the hike, there’s nothing wrong with simply relaxing on a bench and taking in the panoramic view of the lake and its surroundings, which is especially splendid during the cherry blossom and fall seasons.

The perfect daytrip awaits
However you decide to explore Lake Okutama, all it takes is a day trip for a true adventure in nature—convenient yet far removed from the city. It’s a great option for tourists staying in Tokyo as well as locals looking for a place to explore repeatedly throughout the seasons. After you’ve tackled the many trails of Mt. Takao, Lake Okutama is the perfect way to continue exploring the vast mountain ranges just outside of Tokyo proper.
