November to MarchDry, cool and clear: Tokyo’s running season.
Tokyo MarathonSunday 7 March 2027, Shinjuku to Tokyo Station.
Race season, liveChecked every day against each official site.
Where to run
Tokyo is enormous and almost flat, threaded with rivers and old gardens. These are the twelve places its runners actually use, with the rules each one asks you to keep.
The palace loop
Five kilometres, no traffic lights, and one direction for everyone. Flat along the moats from Sakuradamon to Takebashi, a climb to Chidorigafuchi, level to Hanzomon, then the long descent home beside the widest moat in Tokyo.
Sakuradamon桜田門Nijubashi二重橋Otemon大手門Takebashi竹橋Chidorigafuchi千鳥ヶ淵Hanzomon半蔵門The climbThe long descentRun stations
Lockers and showers by the loop. Check prices and hours before you go.
JOGLIS
Showers and lockers close to the west side of the loop.
Raffine Running Style
Showers and lockers from about ¥800 to ¥1,000 a visit.
The running year
Tokyo gives you two running seasons and asks you to survive the third. From November to March the air is dry and the sky is blue. From June to September the heat and humidity decide what you can do.
Spring
March to May
Cherry blossom along the canals and the race season’s last weeks. Cedar pollen runs from about mid-February to April and cypress from March to May: sunglasses help if you react. Shinjuku Gyoen bans running in its cherry weeks.
Rainy season
About 7 June to 19 July
Kanto’s rainy season normally runs from about 7 June to 19 July, though the dates move every year. Warm rain, high humidity, slick stone and paint. A brimmed cap and a light shell beat an umbrella.
Summer
July to September
August averages a 31°C high with 74% humidity. The sun is up by about 4:30 in June, and so are Tokyo’s runners. Go at first light, slow down without guilt, and drink salt as well as water.
Typhoons
July to October, peak in September
About three typhoons a year come close to Kanto, most often in September. Riverside paths flood and trains stop. When one is forecast, stay off the river paths and check the Japan Meteorological Agency.
Autumn
October to November
October is still wet, then the air dries, the ginkgo and maples turn, and the heat alerts end. Long runs come back, and so does the race calendar.
Winter
December to February
Tokyo’s secret: dry, sunny, rarely below freezing, with Mount Fuji on the horizon. January averages a 10°C high and most of Japan’s marathons happen now. Sunrise is near 7:00, so early runs start in the dark.
When the heat decides
Japan measures heat for exercise with the WBGT index, which counts humidity and sun as well as temperature. The Ministry of the Environment issues a Heatstroke Alert when the day’s maximum is forecast at 33 or higher: the evening before at about 17:00, and again at about 5:00. In 2026 the alert season runs from 22 April to 21 October.
Stop exercising
運動は原則中止Exercise should stop except in special cases. Move the run indoors or to tomorrow morning.
Severe warning
厳重警戒Avoid hard sessions and long runs. Rest every 10 to 20 minutes and replace water and salt.
Warning
警戒Take active breaks, about every 30 minutes during hard work.
Caution
注意Normal precautions: drink before you are thirsty and watch for warning signs.
Japan Sport Association guideline for exercise. Below 21, normal care.
Today’s heat indexWhat to wear and carry
A Tokyo year asks for four wardrobes: mesh for the wet heat, a brim for the rain, layers for the dry cold, and lights for the evening runs after work.
Summer
Less fabric, more air, and something white on your head.
- Mesh singlet and split shorts
- A light cap you can soak at a fountain
- A small towel: many Japanese runners carry a tenugui
- Sweat-proof sunscreen for the 5:00 sun
Heat days
For the weeks when the heat index decides your run.
- A bottle frozen overnight: cold water for the first half
- A cooling towel round the neck
- Electrolyte tablets or a salty snack
- Check the heat index (WBGT) before you leave
Rainy season
Warm rain needs a brim, not a coat.
- A packable shell for the cool end of June
- A brimmed cap to keep rain off your eyes
- A waterproof pouch for your phone and IC card
- Shoes with grip: wet paint and stone are slick
Winter
Dry and cold at dawn, warm by ten.
- A thin merino long-sleeve
- Light gloves and a neck gaiter
- A wind shell for the river paths
- Layers you can tie round your waist
After dark
Tokyo is safe at night; the cyclists cannot always see you.
- A clip-on red light on your back
- A reflective vest for the river paths
- A headlamp for unlit riverbanks and parks
Race day
Nothing new on race day. Everything here has been on a long run.
- Your race shoes, broken in over two or three long runs
- Thin socks you have raced in before
- Gels you have trained with
- A throwaway layer for the start pen
Fuel
Practise eating on the run, the same way you practise running.
- Gels or jelly pouches every 30 to 45 minutes on long runs
- A soft flask that packs flat
- Salt in summer, even on shorter runs
Trails
For Takao, Okutama and beyond.
- A vest with soft flasks
- Shoes with lugs for roots and mud
- A bear bell for the quiet trails
- A charged phone and a paper map
Daily shoes
Two pairs in rotation beat one pair worn out.
- A cushioned trainer for easy and long runs
- A second pair with a different feel
- Retire them when the foam feels flat, not when the upper tears
Always carry
Small things that save a run.
- An IC card (Suica or PASMO): the train home, and drinks from most station vending machines
- Some coins for older machines and lockers
- Your ID: foreign residents aged 16 and over must carry their residence card
After the run
The long run ends at the bath, not at the watch.
- A small towel and soap for the sento
- A foam roller for calves and quads
- Something salty and a rice ball within the hour
Tabi
Split-toe running tabi: the thin-soled shoes some Japanese runners swear by.
- Very little cushioning: build up slowly
- A tenugui, the cotton towel you will see on every runner’s neck
Where to buy it
Japan is home to ASICS and Mizuno, and Tokyo sells running shoes in depth. Try shoes in the afternoon, when your feet are at their largest, and bring the socks you run in.
Older guides are out of date. Nike Harajuku moved next door in September 2025, into the Harajuku Quest building at 1-13-14 Jingumae, and adidas RUNBASE by the palace has closed. Every shop below was open when this guide was checked.

Recover like a local
Tokyo has around 400 public baths, and a long run that ends in a hot bath is a ritual for many local runners. The water is hot: start with a few minutes and drink when you get out.
- Pay and take off your shoes.The adult price in Tokyo is ¥600 since 1 August 2026. Shoes go in the lockers at the door.
- Wash first, sitting down.Scrub at the taps before you get into any bath. Rinse off all the soap.
- Keep your towel out of the water.Fold the small towel on your head or leave it at the side. Tie up long hair.
- No swimsuits.Everyone bathes without clothes, in separate men’s and women’s sides.
- Dry off before the changing room.Wipe down with your small towel so you do not drip on the floor.

Watch the Hakone Ekiden
On 2 and 3 January, university teams relay a sash 217.1 km from Otemachi to Lake Ashi and back. It is one of the most watched sporting events in Japan. Good places to stand:
- Otemachi, for the start (2 January) and the finish (3 January).
- Rokugo Bridge, after km 17 of the first leg.
- Gontazaka hill, on the second leg.
- The Route 134 coast on the third leg, with Mount Fuji behind the runners.
- The climb of the fifth leg, to its high point near 874 m, then the torii at Hakone Shrine.
And London
This guide began as a plan for one runner training in Tokyo for London. A Tokyo winter is ideal preparation, and the last long runs fall in cherry season. What to know for 2027:
- A double marathon: 45,000 runners on Saturday 24 April and 55,000 on Sunday 25 April.
- The ballot is closed: 1,338,544 people entered.
- Charity places are still possible through the official site.
- Tokyo is eight hours ahead of London in late April (British Summer Time), so start shifting your sleep a week early.

RETO Running Club

Manners and safety
Tokyo works because people share tight spaces with care. Runners are guests on the pavement; run like one and the city opens up.
Walkers first
On shared pavements, pedestrians have priority. Slow down rather than weave.
Go with the flow
The palace and Komazawa loops run counter-clockwise. Never run against them.
Keep it single file
At narrow points, run in a line and wait to pass.
Small groups
Large groups need permission at the palace (20 or more) and are not allowed in Shinjuku Gyoen (10 or more).
Bins are rare
Carry your gel wrappers and bottles home, or use the recycling bins beside vending machines for bottles only.
If the ground shakes
Phones sound an Earthquake Early Warning. Move away from walls, vending machines, poles and glass, and watch for falling objects.

A plan that knows what today is for
Tell it how much you run, how many days you have and which race you are aiming at. Every day it gives you one thing to do, and it adapts when life gets in the way: a lighter week when you are tired, short runs when you travel, walk-run when something hurts. It stays on this device. No account.
