Okutama & Chichibu: Tokyo's Wild Backyard

The Mountains Tokyo Forgot

Tokyo's western edge dissolves into mountains so abruptly that it feels like a cartographic error. The Chuo Line carries millions of commuters through Shinjuku every morning, but follow the JR Ome Line to its terminus and you step off at Okutama Station, a wooden platform surrounded by cedar forest, the Tama River thundering through a gorge below, and not a convenience store in sight. This is still technically Tokyo. The 23 special wards are less than 80 kilometers away. The disconnect is total.

Across the prefectural border into Saitama, Chichibu occupies a basin ringed by the same mountain chain. Where Okutama is pure wilderness, hiking trails, gorges, caves, Chichibu adds a layer of human devotion: 34 Kannon temples scattered across the hills, a night festival that draws 200,000 people each December, and a relationship with its landscape that feels almost devotional. Together, the two areas form a weekend circuit that is the best antidote to Tokyo available without an overnight train.

Okutama Hiking and Nippara Cave

Okutama's trail network radiates from the valley floor into the Chichibu-Tama-Kai National Park. The most popular route climbs Mount Kumotori (2,017m), Tokyo's highest point, though this is a serious two-day hike requiring a mountain hut reservation at Kumotori-sanso (¥8,500 with two meals). For day-hikers, Mount Mitake is the more practical choice: a cable car (¥600 one way) lifts you to 831 meters, and the Musashi-Mitake Shrine at the summit has guarded the mountain for over 2,000 years. The Rock Garden Trail descends from Mitake through mossy boulders and small waterfalls to Okutama Station in about three hours.

Nippara Limestone Cave, a 20-minute bus ride from Okutama Station, is the largest accessible limestone cave in the Kanto region. The 800-meter walking route threads through chambers of stalactites and flowstone formations illuminated by colored lighting, dramatic, if occasionally garish. The cave maintains a year-round temperature of 11°C, which makes it a refuge from both summer heat and winter cold. Entry is ¥800, and the cave takes about 40 minutes to walk through. The bus from Okutama Station runs roughly every hour; check the timetable before committing, because missing the last return bus means a long walk or an expensive taxi.

Chichibu's 34 Kannon Temples

The Chichibu 34 Kannon Pilgrimage is one of Japan's oldest temple circuits, established in the early Kamakura period (13th century). The route visits 34 temples dedicated to Kannon, the bodhisattva of compassion, spread across the Chichibu basin and surrounding hills. Walking the full circuit takes five to seven days. Most modern pilgrims drive or take buses, completing it in two to three days, but even visiting a handful of temples captures the spirit of the route.

Temple 1, Shimabuji, starts the circuit in central Chichibu and sets the tone: a modest wooden hall, a stamp desk where a monk brushes your pilgrimage book (nokyocho, ¥300 per temple), and a quiet garden. The temples vary wildly in scale and setting. Temple 4, Kinshouji, sits on a hillside above the city with views across the entire basin. Temple 28, Hashidate-do, is built into a cliff face, the hall literally emerges from rock. Temple 32, Hoji-in, sits in deep forest at the end of a steep mountain path. Each temple charges a ¥300 stamp fee, and the complete nokyocho becomes a personal devotional artwork.

Nagatoro River Gorge

Nagatoro, on the Chichibu Railway line, sits at the point where the Arakawa River cuts through a geological layer cake of schist, limestone, and crystalline rock. The gorge walls display patterns of folded and fractured stone that are so textbook-perfect they are designated a national natural monument and used in university geology courses. The Iwadatami rock terraces, broad, flat slabs of crystalline schist layered like tatami mats along the riverbank, are the most photographed feature.

River boat rides (nagatori kudarai) run a 3-kilometer stretch of the gorge, navigated by boatmen using long poles. The ride costs ¥1,800 and takes about 20 minutes, passing through calm pools and mild rapids. The boatmen narrate the geological features in Japanese, pointing out rock formations with names like 'screen rock' and 'elephant rock.' In autumn, the gorge walls blaze with maple and zelkova color, and the combination of red leaves reflected in green water against gray stone is worth the day trip alone.

Chichibu Night Festival

The Chichibu Yomatsuri (Night Festival), held December 2-3, is one of Japan's three great float festivals and a UNESCO Intangible Cultural Heritage. Six massive yatai floats, wooden structures up to 7 meters tall, weighing 12-20 tons, decorated with gold lacquer and elaborate carvings, are hauled through the streets by teams of hundreds. The climax comes on the evening of December 3, when the floats are dragged up a steep hill to the Chichibu Shrine grounds while fireworks explode overhead.

The combination of massive illuminated floats, thundering taiko drums echoing off the surrounding mountains, coordinated chanting from the hauling teams, and winter fireworks bursting above creates an atmosphere of controlled frenzy. The festival draws 200,000-300,000 visitors to a city of 60,000, so advance accommodation booking is essential. Many visitors stay in nearby Yokoze or Hanno and take the train in.
