alk about cycling in Tokyo and the conversation goes to backstreets and temples. But the best cycling in Tokyo is probably not in the centre at all. It is out west, where the Tama River comes down out of the mountains and spreads across the plain — roughly 53 km of riverbank from there to the sea, with almost no traffic lights, almost no gradient, and sky filling half the view.
Silver grass and gravel flats, water dropping over a weir, apartment blocks standing along the far bank, and on clear days Mount Fuji upstream. All of it less than an hour by train from central Tokyo.
There is one thing to understand before you go, though, because most English guides get it wrong.
Quick Facts (at a Glance)
- The route: Hamura Weir → Fussa → Tachikawa → Fuchu → Inagi → Futako-Tamagawa
- Distance: about 36 km (around 53–55 km if you ride to the river mouth)
- Elevation gain: roughly 140 m over the whole thing. Effectively flat
- Time: 3–3.5 hours riding, 5–6 hours with stops
- Level: beginner-friendly, but the surface and the pedestrians need attention
- Direction: always downstream. From October to December that means a tailwind
- Lighting: essentially none anywhere. Finish before sunset
First: This Is Not a Cycle Path
It Isn’t One Road — It’s a Patchwork of Municipalities
What English guides call “the Tama River Cycling Road” is not a single facility. It is a chain of separately owned, separately named paths on both banks. The left bank in Tokyo is branded Tama River 50km (the distance markers run from 0.0 km at Daishibashi Riverside Park in Ota Ward to 53.0 km at Hamura Weir). The right bank through Kawasaki is the Kawasaki Tamagawa Fureai Road (21.4 km). Through Fuchu it is Fuchu Tamagawa Kaze-no-michi (about 10 km). Inagi, Fussa, Akishima, Hino and Hachioji each have their own named sections.
No single manager, no single rule set, no uniform surface.
Legally It Is Not a Road, and Pedestrians Have Priority
These paths are not jitensha-do — dedicated bicycle carriageways under the Road Traffic Act. They sit on national river land, built by each municipality under river-law occupation permits. Fuchu’s section is managed as a city park, not a road at all.
The consequence: bicycles do not have priority. Every manager that publishes rules publishes pedestrian priority. Inagi and Kawasaki both instruct that pedestrians keep left too — the opposite of normal Japanese convention — because the path is only 2 to 2.5 metres wide. Fuchu inverts the layout, putting walkers on the right edge and cyclists in a centre-left lane. Cross from Inagi into Fuchu and the convention changes under your wheels.
No numeric speed limit is posted anywhere. Instead you are slowed physically. Kawasaki installed speed humps in December 2020; Fuchu and Chofu built ridges into the paving, both explicitly described as being there to hold cyclists’ speed down.
And It Is Not Continuous
This is the part that matters most. The documented breaks include:
- Hamura Weir: there are steps beside the embankment, then 700 m of unpaved track, then a dead end at Aso Shrine
- The JR Chuo Line bridge: the path vanishes on both banks. On the right bank it simply ends and you drop down to the riverbed; on the left the embankment dead-ends and you pass under the viaduct
- Chuo Expressway bridge: bollards, then out onto a public road
- Tama-Ohashi: no direct crossing. You detour through housing, fields and an underpass
- Tamabashi to Nagatabashi (right bank): no cycling path at all — residential streets
- Tama-Suido-bashi to Marukobashi (left bank): runs through sports grounds and onto public roads, with gravel. Not suitable for continuous riding
- Futako-Tamagawa (right bank): 2–3 km on public roads, and the marked running-track section is closed to bicycles
There is good news too. Komae’s unpaved stretch was paved in August 2021, and Tama-Suido-bashi to Tamagawahara-bashi was fully paved by February 2022. The Futako-Tamagawa section damaged by Typhoon Hagibis in 2019 was diked, and the pedestrian and cycle path became fully usable again around November 2025.
One warning: there is no single official page listing current closures for this route, because there is no single manager. Closures here are local, frequent and often unannounced.
So You Ride Downstream
From October to December the Wind Is Behind You
Japan Meteorological Agency monthly statistics give the most frequent wind direction in Tokyo in October, November and December as northwest. The Tama runs northwest (Hamura) to southeast (the river mouth). In autumn and early winter, riding downstream is genuinely wind-assisted.
Plan it one-way and take the train home. The JR Nambu Line runs parallel to the river from Kawasaki all the way to Tachikawa, so you can bail out almost anywhere.
Northwest is the month’s modal direction, not a guarantee — a daytime sea breeze from the south can reverse it, so start in the morning. Worth knowing: northwest-wind days are the dry, clear ones, which is exactly when Fuji is visible.
Realistically, 35–40 km of It Is Good Riding
Of the 53 km, something like 35 to 40 km is continuous, paved, beginner-grade surface. Several independent route guides advise turning back around Tachikawa or Hino if you want to avoid gravel and public-road sections.
This article uses Hamura to Futako-Tamagawa, about 36 km, because that is where the riding is actually good.
Getting a Bike
Local Share Cycles — the Easiest Option
Tachikawa has run a HELLO CYCLING scheme since April 2022 with 77 stations in the city, including one at Showa Kinen Park. Chofu had 125 ports as of January 2026. Fuchu, Inagi, Kokubunji, Komae and Mitaka all have coverage. All electric-assist; roughly ¥160 per 30 minutes, then ¥160 per 15 minutes, with a 12-hour cap around ¥2,500.
The Share-Cycle Trap
No English guide seems to mention this, so here it is plainly: HELLO CYCLING and docomo bike share are different, non-interoperable systems.
The Tama River route crosses from HELLO CYCLING territory (Tachikawa, Fuchu, Chofu, Inagi) into Setagaya’s self-contained Gaya-rin scheme, which only allows returns within Setagaya, and then into docomo’s network in Ota. You cannot ride one share cycle down the length of this river. A bike hired in Tachikawa cannot be returned at Futako-Tamagawa or Haneda.
Billing also continues while the bike is parked, so a five-hour sightseeing pace will hit the 12-hour cap regardless.
Bringing a Bike from Central Tokyo
For your own bike or a proper rental, take it on the train. CycleTrip BASE (2-9 Kanda Sudacho, Chiyoda-ku — four minutes’ walk from JR Akihabara, open daily 09:30–17:30) rents cross bikes from ¥4,500 for the first day and electric-assist city bikes at ¥4,500–7,500, with lock, lights and liability insurance included. From there it is about an hour to Hamura on the Chuo Line, changing to the Ome Line at Tachikawa.
The essentials on rinko, taking a bike on a train: on JR East a bicycle travels free as hand luggage provided it is fully disassembled and stored in a dedicated bag (three dimensions totalling 250 cm or less, 30 kg or less). Keio, Odakyu, Tokyu and Seibu work on the same bagged-bicycle principle. A bike wheeled onto a platform uncovered will be refused.
The Route: Hamura to Futako-Tamagawa, About 36 km
1. Hamura Weir — the 1653 Starting Point
The upstream terminus and the 53.0 km marker. Hamura Weir was built in 1653 as the intake for the Tamagawa Josui aqueduct, and alongside the long modern fixed weir it still has a nagewatashi-zeki — a traditional removable weir whose boards are taken out to let floodwater through.
Hamura Sekishita Bridge is pedestrian-and-bicycle only, so you can switch banks here. The hills above the weir are Hamura Sōka Hill Natural Park, but that is a walking area — don’t try to ride up it.
2. Fussa to Akishima — Take the Left Bank
Through here only the left bank works. The right bank is broken by unpaved sections, public-road detours and the Aki River confluence; between Haijima-bashi and Mutsumi-bashi it becomes a series of unpaved farm tracks.
This is also the thinnest stretch for supplies on the whole route. Between Hamura and Akishima you cannot count on a convenience store or a water point. Buy what you need near Hamura Station.
3. Tachikawa and Showa Kinen Park — Not a Detour, the Main Event
This is the stop that defines the day.
A 14 km Cycling-Only Course
Showa Kinen Park has a 14 km cycling course that is closed to pedestrians — the exact inverse of the riverbank you have just ridden. The official guide prohibits riding against the flow and leaving the course, and there are four roundabout-style junctions.
There are not many places in Japan where cyclists have priority this completely. After an hour of yielding to walkers on a two-metre path, it lands.
Rentals and Bringing Your Own
You can bring your own bike in, and the Tachikawa and Nishi-Tachikawa gates have dedicated bicycle entrances. Normal admission applies: ¥450 adult, ¥210 for 65 and over, free under 15. Riding or pushing a bike anywhere outside the course is prohibited.
Rentals run from three cycle centres with roughly 2,000 bikes between them: ¥600 for three hours or ¥800 for a day, cross bikes ¥800 for three hours, tandems ¥1,500. Front and rear child seats are available, which makes this the answer if you are riding with family. Reception runs from opening until an hour before closing.
The park opens at 09:30 and closes at 17:00 from March to October, 16:30 from November to February. Use the Nishi-Tachikawa gate — two minutes from JR Nishi-Tachikawa Station, with both a bicycle entrance and a cycle centre.
The Ginkgo Avenue in November
This is where the autumn colour is on a flat route. The park’s own foliage updates put the ginkgo avenue and Japanese garden at their peak in mid-to-late November, and during its autumn festival both are lit in the evening.
Be clear about this: the Tama floodplain itself has no autumn foliage. It is grass and sky. On a flat ride, the colour is in the parks.
4. Tachihi Bridge to Fuchu — and Okunitama Shrine
The Tama Monorail crosses overhead at Tachihi Bridge, which makes it the best bail-out point on the route.
A short ride inland near Korematsu Bridge brings you to Okunitama Shrine, the head shrine of the old province of Musashi. The grounds are free, open 06:30–17:00 from 15 September to 31 March. Five minutes’ walk from Keio Fuchu Station’s south exit or JR Fuchu-Hommachi. It is the best cultural stop available on a flat river route.
5. Korematsu Bridge to Inagi — the Best Riding of the Day
Fuchu’s Kaze-no-michi runs into Inagi’s cycling course, built in 1970 and connected through to Kawasaki’s side in March 2018.
The surface is good, the width about 2.5 m, and the view opens out. This is the stretch where the kilometres go by most easily. The slopes to the north are Inagi’s pear orchards — though the pear season runs from late August into September, so from October they are landscape rather than a shopping stop.
6. Tama-Suido-bashi — the Decision Point
Here you choose. The left bank downstream of this point is poor — sports grounds, public roads, gravel. If you are riding to the mouth, cross to the Kawasaki side here or at Marukobashi.
The Kawasaki side has its own compromises: 2–3 km of public road near Futako-Tamagawa, and a running-track section closed to bicycles.
7. Futako-Tamagawa — the Natural Finish
Thirty-six kilometres. There are toilets and a Starbucks at Futako-Tamagawa Park, and the Tokyu Den-en-toshi and Oimachi lines take you back into the city. The river mouth is another 18 km, about an hour and a quarter.
Near Marukobashi there is CROSS COFFEE (closed Tuesdays and Wednesdays); the Kawasaki-side rest area at Futakobashi has racks, water and toilets; and the Tamagawa exchange centre near Route 1 has a free floor pump.
If You Have Another Day
Jindaiji and the Jindai Botanical Garden
Just north of Chofu, Jindaiji temple sits at the end of a street of soba restaurants, next door to the Jindai Botanical Garden. The garden is ¥500, open 09:30–17:00 (last entry 16:00), closed Mondays, and free on 4 May and 1 October.
The detail that matters for a cyclist: there is bicycle parking at the main gate and near the Jindaiji gate. One stop covers both the temple and the garden.
Lake Tama, and the Railway That Built It
The Tamako Cycling and Pedestrian Road is formally Tokyo Metropolitan Road Route 253, and in 2018 it was renamed from “Tamako Cycling Road” to Cycling and Pedestrian Road — a rename that tells you what it is. You share it.
About 22 km in total: an 11 km dead-straight section from Nishi-Tokyo to near Musashi-Yamato Station, plus roughly 11 km around the lake. Paved to 4 m width by 2014. The lake circuit is about 12 km with only around 50 m of elevation change. The surface is heaved in places, though — this is not a fast road.
Lake Sayama next door is a different proposition. The dam crest is open to walk, but the perimeter is roughly 60% unpaved forest track, which is hard going on a road or cross bike. Bicycles are not banned there; the surface is simply the obstacle.
Mind the station names. In March 2021 Seibu-Yuenchi Station was renamed Tamako Station, and Yuenchi-Nishi became Seibuen-Yuenchi. Tamako Station (for the lake), Seibuen-Yuenchi Station (for the amusement park) and the pre-existing Seibuen Station are three different places.
The Tunnels on the Noyamakita Cycle Path
Better than the lakes themselves. The Noyamakita Park cycle path runs on the trackbed of the Hamura–Yamaguchi light railway, a temporary 12.6 km line laid in 1929 to haul gravel from the Tama River at Hamura to the Lake Sayama construction site.
About 4 km survives as a cycle path, running through the Yokota tunnel group — a series of former railway tunnels — with some 300 cherry trees along it.
But the tunnels are only open to bicycles during set hours: 07:00–18:00 from April to September, 07:00–17:00 from October to March. In autumn and winter that is a hard constraint.
And the reason it is a good story: the western end connects to the Tamako path, and the eastern end heads for the Tama River at Hamura. You can follow the railway that built the lake back to the river it took its gravel from.
The Asakawa Cycling Road
Hino’s Asakawa Cycling Road and Hachioji’s Asakawa Yuttari Road run continuously for about 20 km from Fuchu-Yotsuya Bridge to Ryonan-Ohashi. Less traffic than the main Tama route, with riverside parks as rest stops.
One connection note: the downstream end is on the right bank of the Tama, while the main Tama route runs on the opposite side. Joining the two means crossing the bridge.
Rules on the Floodplain
From the Keihin River Office, which manages the river:
- Open fires are prohibited — vegetation damage and wildfire risk
- Day camping outside a municipally occupied area requires notification. No ground fires; use a gas stove so heat does not transfer to the ground
- Drones: there is no river-manager-approved RC or drone field anywhere on the Tama
- Swimming is prohibited in signed danger zones, especially near weirs
- Barbecues vary by city. Komae bans them outright, all day, by ordinance, in its Tama River conservation zone
Riding This from October to December
Sunset falls at 17:26 on 1 October, 16:47 on 31 October, and around 16:30 by December. Almost none of this route is lit. Treat 16:30 as the hard stop in October and 16:00 in December. A Hamura-to-Haneda day needs a start no later than about 09:00 even in October.
The wind is northwest, so downstream is assisted — and those are the dry, clear days when Fuji appears. Typhoon season runs into early October, and the river office warns about sudden rises in water level. Check the forecast before you set out.
Wrap-Up
The Tama is not a purpose-built cycle route. It is a chain of two-metre, pedestrian-priority maintenance paths and parks, broken in a dozen places, with ridges built into the tarmac specifically to slow you down.
It is also one of the best places to ride a bicycle in Tokyo. No traffic lights, no hills, a tailwind in autumn, a 1653 weir at one end and a city riverside at the other — and a 14 km traffic-free course with a ginkgo avenue in the middle of it.
Leave Hamura in the morning and ride downstream. Remember who has priority. Finish before the light goes. Then take the Nambu Line home.
