When most people think of Tokyo, they imagine skyscrapers, neon lights, and crowded trains. But just two hours from Shinjuku, there’s a completely different world waiting to be explored. Okutama is Tokyo’s lush mountain region, offering rivers, caves, hiking trails, and small-town charm that feel a universe away from city life. Whether you’re into rafting down roaring rivers, soaking in hot springs, or hiking to misty peaks, there’s something here for you. It’s Tokyo’s hidden nature escape—and one of my favorite weekend getaways.
Lake Okutama
Lake Okutama is a vast, man-made reservoir that supplies much of Tokyo’s drinking water. Located at the western edge of the city, it offers dramatic views of forested mountains reflected on blue-green waters. The most accessible viewpoint is Ogouchi Dam, reachable by bus from Okutama Station. The dam also marks the end of the popular Mukashi Michi hiking trail. If you’re up for a unique experience, you can cross the lake on foot using either the Tozura Floating Bridge or the Mugiyama Floating Bridge—just note that they’re each a bit out of the way and require additional bus rides.
Mugiyama Floating Bridge
This striking floating bridge snakes across Lake Okutama, offering a surreal, slightly bouncy crossing experience. Located several bus stops past Ogouchi Dam, it’s more remote but rewards the effort with peaceful views and fewer crowds. A short walk uphill takes you to Ogouchi Shrine, a secluded place of worship built to honor the shrines submerged when the dam was created. Mugiyama is also near trailheads like Mt. Mito, making it a good spot for nature lovers and hikers.
Tozura Floating Bridge
Tozura Bridge is slightly more accessible than Mugiyama and tends to be the preferred choice for visitors using public transport. While it’s still a bit of a journey from Okutama Station, the area around the bridge has amenities like toilets, vending machines, and a small restaurant. Like Mugiyama, it floats across the reservoir, giving you a unique vantage point of the lake and surrounding mountains.
Ogouchi Shrine
A short uphill walk from Mugiyama Floating Bridge, Ogouchi Shrine is a peaceful spot with views over Lake Okutama. The shrine was built to enshrine the deities of several villages that were submerged when the dam was constructed. It’s a quiet place for reflection, often overlooked by tourists. The surrounding forest adds to its mystical atmosphere, especially on misty mornings or late afternoons.
Hatonosu Valley
Just a short train ride from Okutama Station, Hatonosu Valley is a scenic gorge carved by the Tama River. A suspension bridge spans the ravine, giving you dramatic views of river rapids and lush, seasonal foliage—especially stunning in fall. It’s part of the Otama Walking Trail, which includes large boulders and gentle climbs. While swimming is not allowed, the area is perfect for riverside picnics, photos, or simply sitting on the rocks and enjoying the view.
Gallery Poppo
Located just across the suspension bridge in Hatonosu Valley, Gallery Poppo is a quirky little cafe with a handful of counter seats that overlook the river. They serve comforting meals like soup curry, pizza toast, and homemade desserts, making it a great lunch or coffee stop during your hike or walk in the area. The relaxed, lived-in atmosphere adds to its charm.
Riverside Cafe Awa
Tucked along the banks of the Tama River, Riverside Cafe Awa offers a more modern and peaceful riverside dining experience. With terrace seating and large windows, it’s the kind of place where you can sip coffee or enjoy a full meal while watching the water flow by. The menu changes seasonally and includes fresh, locally sourced ingredients. It’s also a short walk from the Seseraginosato Museum, so you can easily combine both in one stop.
Shiromaru Dam
Shiromaru Dam is a concrete gravity dam on the upper Tama River and one of the highlights of the Otama Walking Trail. You can view the dam from an observation deck, and one of its most fascinating features is the fish ladder—the longest of its kind in Japan—designed to help fish migrate upstream. The area around the dam is lush and quiet, and the trails offer moderate hiking for those who want to escape the crowds.
Nippara Limestone Caves
Located deep in the mountains and accessible via a 40-minute bus ride from Okutama Station, the Nippara Limestone Caves are the largest in the Kanto region. About 800 meters of tunnels are open to the public, with rock formations lit by multicolored lights. Inside, you’ll find a statue of Kannon (the goddess of mercy), believed to grant love-related wishes. The cave stays a cool 11°C year-round, so bring a jacket. There are few food options nearby, so it’s best to bring snacks or plan a meal before or after your visit.
Ozawa Sake Brewery (Sawanoi)
Founded in 1702, Ozawa Sake Brewery—also known by its brand name Sawanoi—is the oldest sake brewery in Tokyo. You can sample over 10 kinds of sake for around ¥400–¥500 per cup in their riverside garden, Sawanoi-en. There’s also a gift shop, and food stalls often operate on weekends. Brewery tours are available with reservations and often fill up fast. The location is serene, and you can even walk down to the river for a quick dip or just enjoy the views.
Moegi no Yu
Just a 10-minute walk from Okutama Station, Moegi no Yu is a well-maintained hot spring with both indoor and outdoor baths offering views of the surrounding mountains. It’s the perfect way to unwind after a day of hiking or rafting. Entry costs around ¥950, and there’s also a restaurant and a free foot bath if you don’t want to go all in.
Seseraginosato Museum
Just minutes from Riverside Cafe Awa, Seseraginosato Museum is housed in a traditional-style building and features a rotating display of calligraphy, paintings, and crafts from local artists. The museum is small and quiet but worth a visit if you enjoy art or want a cultural break between outdoor activities. Admission is free, and you can enjoy a short visit before heading to your next stop. serves as Tokyo’s major freshwater source. The vast lake can be enjoyed from different vantage points, the most popular of which is Ogouchi Dam, where the buses headed for Lake Okutama take its passengers. Ogouchi Dam marks the eastern end of the lake and is also the culminating point of the Mukashi Michi hiking trail. Travelers who wish to cross the lake on foot can do so at two different points: the Tozura Floating Bridge and the Mugiyama Floating Bridge.
Odd Spots & Bizarre Locations in Okutama
Abandoned Ropeway
Built in 1961 and closed just five years later, this eerie structure now stands unused over Lake Okutama. The Mitosanguchi side is more accessible, though locals may discourage visitors from using the Kawano side.
Okutama Factory
Located 10 minutes from Okutama Station, this massive industrial plant looks like a steampunk movie set. Adventurous visitors can follow tracks into the woods to discover abandoned rail dollies.

Okutama is a hiker’s paradise, with scenic trails that range from gentle forest paths to more rugged mountain routes.
