ASICS Run Tokyo Marunouchi
Lockers, showers, rental shoes and kit, a form lab, and daily group runs. Weekdays 6:30 to 21:30, weekends 7:30 to 19:00.
A field guide to running in Tokyo. Where to run, what to wear in each season, where to buy it, how to fuel from a konbini, which races to enter, and a plan that tells you what to run today.
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.
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.

Lockers, showers, rental shoes and kit, a form lab, and daily group runs. Weekdays 6:30 to 21:30, weekends 7:30 to 19:00.
Showers and lockers close to the west side of the loop.
Showers and lockers from about ¥800 to ¥1,000 a visit.
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.

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.

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.

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.

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.

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.

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.
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.
Exercise should stop except in special cases. Move the run indoors or to tomorrow morning.
Avoid hard sessions and long runs. Rest every 10 to 20 minutes and replace water and salt.
Take active breaks, about every 30 minutes during hard work.
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 indexA 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.

Less fabric, more air, and something white on your head.

For the weeks when the heat index decides your run.

Warm rain needs a brim, not a coat.

Dry and cold at dawn, warm by ten.

Tokyo is safe at night; the cyclists cannot always see you.

Nothing new on race day. Everything here has been on a long run.

Practise eating on the run, the same way you practise running.

For Takao, Okutama and beyond.

Two pairs in rotation beat one pair worn out.

Small things that save a run.

The long run ends at the bath, not at the watch.

Split-toe running tabi: the thin-soled shoes some Japanese runners swear by.
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’s Harajuku flagship closed in August 2025, adidas RUNBASE by the palace has closed, and so has Bain Douche, the runners’ bath at Hanzomon. Every shop below was open when this guide was checked.

The sports drinks of Japan. Cold, everywhere, and the easiest way to replace salt on a summer run.
Spouted pouches of carbohydrate jelly, such as Morinaga’s in Jelly. Japanese runners’ favourite pre-run breakfast and long-run fuel.
Simple carbohydrate before a long run or after it. Plain salted rice balls (shio musubi) go down easily.

Japanese race gels (Mag-on carries magnesium) and Medalist’s citric acid drinks, sold by specialists such as Stride Lab.
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.

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:
Tokyo’s clubs are free, friendly and used to newcomers. Most announce the week’s runs on Instagram, LINE or Strava, so follow before you show up.
The English-speaking club. Wednesday 19:30 track workout at Oda Field (when open), then the sento and a drink in Yoyogi-Hachiman.
Three or four runs a week at rotating spots, mornings 6:30 to 9:00 and evenings 18:00 to 21:00. Posted a day or two ahead on Instagram, LINE and Strava.
A relaxed crew in Yoyogi Park on Monday evenings (20:10) and Saturday mornings (9:00). Check Instagram for the meeting point.
The Tokyo Marathon Foundation’s club: events, training content, and a separate entry draw for repeat lottery losers.
ASICS Run Tokyo Marunouchi (daily, by pace group), Nike Ginza, On Tokyo in Ginza and HOKA Harajuku host group runs. Check each store’s channels for the week.
Coached sessions led by a former Asian marathon champion, at changing venues.
Tokyo works because people share tight spaces with care. Runners are guests on the pavement; run like one and the city opens up.
On shared pavements, pedestrians have priority. Slow down rather than weave.
The palace and Komazawa loops run counter-clockwise. Never run against them.
At narrow points, run in a line and wait to pass.
Large groups need permission at the palace (20 or more) and are not allowed in Shinjuku Gyoen (10 or more).
Carry your gel wrappers and bottles home, or use the recycling bins beside vending machines for bottles only.
Phones sound an Earthquake Early Warning. Move away from walls, vending machines, poles and glass, and watch for falling objects.

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.
