Look for the Golf Bridge, a red arched steel bridge over the valley entrance. The path goes down from the east bank. If you want something to eat in the park, stop at the Seijo Ishii supermarket near the station before you head down; it has imported cheeses, bread and deli items as well as Japanese bento.

The Yazawa River carved the valley as it cut through the Musashino plateau over a very long time, and you can see the history in the walls. The exposed cliffs show layers of clay, fine sand and gravel, topped by reddish-brown Kanto loam (関東ローム層), a volcanic ash deposit that covers much of the Kanto plain. You don't need any geology to read them: darker bands at the base, lighter sediment above, and the ochre loam over everything. More than thirty natural springs seep out of the plateau along the length of the gorge, which is a lot of groundwater for one small valley. That concentration of springs put Todoroki on Tokyo's official list of 57 Famous Springs (東京の名湧水57選).

The Yazawa River runs beside the path, clear and narrow, with small red bridges crossing it at several points. Overhead the canopy is dense. The main trees are keyaki (Japanese zelkova), shira-kashi (evergreen oak), konara (sawtooth oak) and yamazakura (wild mountain cherry). Near the springs, where it's damper, ferns grow thickly enough to make the lower path look almost prehistoric. You'll hear birds well before you see any. The valley walls were too steep to build on, which is why so much of the natural vegetation has survived.

About halfway along, a temple complex appears on the left bank. Its formal name is Mangan-ji (満願寺), but most people call it Todoroki Fudōson, after the main object of worship in its valley chapel. That chapel's full official name is Ryūgōzan Myōō-in (滝轟山明王院), the Temple of the Thundering Waterfall King of Wisdom, which gives you a fair idea of the place before you get there.

According to the founding legend, a high priest named Kakuban (覚鑁上人, 1095–1143), later known as Kōgyō Daishi and revered for reviving Mount Kōya and the Shingon sect, had a dream in which Fudō Myōō appeared to him. Fudō Myōō is the immovable wisdom king, patron of perseverance and ascetic discipline, and in the dream he told Kakuban to enshrine a statue in Musashi Province at a place with plenty of water. Kakuban searched the area, found the Todoroki ravine, struck the cliff with his staff, and a spring gushed out. That spring became the Fudo Waterfall (不動滝). The Fudō Myōō statue he enshrined above it is said to date from the Nara period. The water, which now pours from the mouths of two carved stone dragons, is still considered sacred.

The valley's name comes from this waterfall too. "Todoroki" is from todoroku (轟く), to roar or thunder, after the sound of the falls echoing up the gorge. Another theory links the name to a local castle, Todorojō, owned by a feudal lord named Nanjo Shigenaga, but the waterfall explanation is the more widely accepted one and the more direct fit linguistically.

The temple was revived in 1470 as a chapel for Todoroki Castle, grew into a full seminary temple during the Muromachi and Sengoku periods, and received a stipend of 13 koku from the Tokugawa shogunate in the Edo period. Today it belongs to the Shingon-shū Chisan-ha school and is the 17th temple on the Bandō Sanjūroku Fudōson Reijō, a pilgrimage circuit of 36 Kantō-region temples dedicated to Fudō Myōō. People still come here to pray, and it is very much a working temple.

The wooden viewing platform above the temple gives the best view from up high in the valley. In late March and early April the trees around it bloom heavily. The cherry blossoms are quieter than at Nakameguro or Ueno, and you see them against filtered light, running water and stone lanterns. Autumn colour peaks in late October and November, when the gorge goes red and gold and stays far less crowded than Rikugien or Koishikawa Korakuen.

Between the temple and the teahouse, a group of pit graves is cut into the valley wall. This is the Todoroki Valley Yokoana Tomb Group (等々力渓谷横穴墓群): six or more horizontal burial chambers dug into the soft cliff between the 7th and early 8th century, from the late Kofun period into the start of the Nara era. They belonged to powerful local landowners or leading farmers, a community that has left no other physical trace in the neighbourhood.

The most complete is the No. 3 pit tomb (3号横穴), a designated Tokyo Metropolitan Historic Site. It is 13 metres long in total, with a burial chamber (genshitsu) joined to a passage (sendō), the standard layout for horizontal tombs of the period. Excavations in 1973 turned up human bones along with earrings and ceramic vessels, belongings of whoever was buried there twelve or thirteen centuries ago.

Most people walk straight past. The openings in the wall are easy to miss, and the signs are only in Japanese. You can still make sense of them without a translation, though: a rectangular cut in the cliff, a low entrance, a shape that was obviously made on purpose. It is one of the odder things you can stumble on in a Tokyo park, and most guides don't mention it at all.

At the far end of the 1.2km path is Setsugekka (雪月花), the teahouse run by Mangan-ji temple. The name means snow, moon and flower, a classical Japanese phrase for the beauty of the seasons. It is a thatched-roof building beside a small koi pond, with bamboo all around. Inside, the decorative umbrellas and low tables are a kind of traditional interior that is getting hard to find even in Kyoto.

The menu centres on wagashi, traditional Japanese sweets. The house speciality is kuzu mochi: translucent arrowroot jelly cakes served cold, dusted with kinako (roasted soybean flour), sliced, and eaten with black syrup. Anmitsu (cubed agar jelly, sweet red beans and fruit in black sugar syrup) and oshiruko (sweet red bean soup with soft mochi) are on the menu all year. In summer people come for the kakigori (shaved ice with syrup), served in a garden screened with bamboo where it's easy to sit for an hour without feeling rushed.

Hours: Weekdays 11:00–16:00 (last order 15:30). Weekends and holidays 10:30–16:00 (last order 15:30). Closed on rainy days and in bad weather. Winter hours are much shorter, so check before you go if the teahouse is the reason for the trip. Phone: 03-3705-8137.

Walking straight through the valley without stopping takes thirty to 45 minutes. With ninety minutes you can look round the temple properly, read the cave tomb markers, and sit down at the teahouse for a plate of kuzu mochi. For a half-day, add Jiyugaoka, 10 minutes away by train, for patisseries, European-style shopfronts and lunch. We like the jump from the wild gorge to those tidy streets.

In spring, cherry blossoms fill the temple grounds in late March and early April. The light through the trees makes for better photos than the busier spots: blossoms against stone lanterns and running water, and far fewer selfie sticks.

Summer is when the cooler air matters most. The canopy and running water lower the temperature in the gorge, and you notice it within a few metres of leaving the street. On a hot August day in Tokyo the valley feels like another climate, and it's also the season when Setsugekka's kakigori makes the most sense.

Autumn colour peaks in late October and November, when the keyaki and konara turn the gorge gold. It is a fine display, and much less crowded than similar spots elsewhere in the city. Winter is the quietest season. The teahouse keeps very short hours then, so check before making it the point of the trip.

The valley has several entrances. Most people go down at Golf Bridge, walk to the teahouse and come back the same way, which skips the better half. For the full loop, go down at Golf Bridge, walk the whole gorge path to the teahouse, then climb the steps up to the streets above and walk back along the upper path, looking down into the canopy. The upper route goes through a neighbourhood of small family houses and local shotengai shops, ordinary residential Setagaya that feels a long way from the tourist circuit. It gets you back to Todoroki Station in roughly 15 minutes on foot.

Give the cave tombs more time than most people do. You can walk right up to the No. 3 tomb, stand at the entrance and look down the carved passage. Those chambers are seventh-century, cut into the cliff of what is now a municipal park in southwest Tokyo, and you can see them on an ordinary afternoon walk.

Locals use the valley in the mornings too: joggers, students on their way to school, groups of retirees out walking. A midweek morning before 10am is the calmest time. By late Saturday afternoon it fills with couples and families. It still isn't crowded by Tokyo standards, but the mood is more day out than quiet walk.

Jiyugaoka (10 min by train): Tokyo's patisserie neighbourhood, with European-influenced streets and lots of good cafés and cake shops. A good place for lunch or an afternoon coffee after the valley.

Gotokuji Temple (nearby in Setagaya): The temple that claims to be the origin of the maneki-neko (beckoning cat) figurine is about 5km from Todoroki Valley. That's a long walk through residential Setagaya, or a short trip with a couple of train changes. The neighbourhood in between is worth walking if you have the time.

Kichijoji (under an hour by train, changing at Shibuya): Inokashira Park is the better-known counterpart in western Tokyo: bigger and more manicured, with a rowing pond and a small zoo. Doing both in the same half-day makes a good nature day on the Tokyu lines.

Ordinary Tokyo covers the residential west, the neighbourhoods and shotengai and other places Tokyo residents actually use, and Todoroki Valley is typical of this part of the city. For a custom day built around the quieter green spaces of western Tokyo, Infinite Tokyo can follow any itinerary you like.

Is Todoroki Valley free to enter?

Yes. There is no admission charge for the valley path, the temple grounds or the cave tomb area. The only cost is food and drink at Setsugekka teahouse if you stop there. Going into the teahouse is free too; you pay only for what you order.

Is the path wheelchair accessible?

No. The path has steps, uneven surfaces and narrow sections, and the way down from the Golf Bridge entrance is a staircase. Most people can manage it in comfortable shoes, but it isn't suitable for wheelchairs or prams.

What time does Setsugekka teahouse close?

It closes at 16:00 every day, with last orders at 15:30. It opens at 10:30 on weekends and holidays and at 11:00 on weekdays. It shuts on rainy days and in bad weather without notice, and keeps shorter hours in winter. If the teahouse is the main reason for your visit, call ahead on 03-3705-8137.

Can I do Todoroki Valley in the rain?

In light rain, yes. The canopy gives reasonable cover, and the valley is lovely when it's grey or misty. Setsugekka teahouse closes in poor weather, though, and the path gets slippery near the steps and river crossings. Avoid it in heavy rain.

What is Todoroki Fudōson Temple dedicated to?

The main object of worship in the valley chapel (Myōō-in) is Fudō Myōō (不動明王), the Immovable Wisdom King, a fierce protective deity in the Shingon tradition. The statue is said to date from the Nara period (8th century). The temple is the 17th stop on a Kantō pilgrimage circuit dedicated entirely to Fudō Myōō, so devotees still come here to pray.
