On an August evening in Tokyo, drums start up somewhere behind a shrine and a ring of people in cotton yukata shuffles around a wooden tower hung with paper lanterns. Shaved ice stands do steady business, shopping arcades hang with bamboo and paper streamers, and the air stays warm long after dark. August is the month of Obon and of the neighborhood dance festivals, a hot, humid stretch of the year when Tokyo is best seen in the evening, with cold noodles in hand.
What is the weather like in Tokyo in August?
August in Tokyo is hot, humid and often sunny, the sunniest of the three summer months compared here, with a rain pattern that comes in fewer, heavier spells than in July or September.
| Month | Average high (°F) | Average low (°F) | Precipitation (in) | Days with 1 mm or more of precipitation | Hours of sunshine | Daylight on the 15th |
|---|---|---|---|---|---|---|
| July | 85.8 | 72.3 | 6.15 | 10.5 | 151 | 14 h 22 min |
| August | 88.3 | 74.3 | 6.09 | 7.9 | 174 | 13 h 33 min |
| September | 81.5 | 68.5 | 8.85 | 11.0 | 127 | 12 h 27 min |
Afternoons reach close to 90, and nights barely cool off, so the heat you feel at dusk is still there at bedtime. Humidity sits in the mid-70s percent, which is what makes the air feel sultry rather than simply warm. Japan’s summers on the main island of Honshu are described as very humid, hot and sultry, and Tokyo fits that description well.
Rain falls on fewer days than in July, but August is not a dry month. A compact umbrella earns its place in a bag, and so does a small towel for your neck.
The light is long without being endless: daylight runs a bit shorter than in July and noticeably longer than in September. That leaves a generous evening for festivals, lantern-lit shrine grounds and a late dinner. Light, breathable layers for outdoors and a thin extra layer for air-conditioned trains, museums and department stores are the whole wardrobe strategy.
What to do in Tokyo in August
The things to do in Tokyo in August revolve around summer festivals, evening dances and cold food. Obon is a Japanese Buddhist custom to honor the spirits of one’s ancestors, when people return to ancestral family places and visit and clean their ancestors’ graves. The festival lasts for three days, and around it the city fills with bon-odori, the circle dances held in shrines, parks and other open spaces, typically from mid to late August.
At a bon-odori you do not need to know the steps. Dancers circle a raised wooden tower where drummers play, the movements repeat, and visitors are often drawn into the ring after a few minutes of watching. People wear yukata, light cotton robes, and food stalls with grilled corn, noodles and shaved ice ring the dancing ground.
Asagaya Tanabata Matsuri
Early in August, the Asagaya Pearl Center Shopping Street, a long covered arcade at the south exit of JR Asagaya Station, turns into the Star Festival. The whole arcade is covered in bamboo decorations and elaborate papier-mâché sculptures that change each time, so the figures overhead are never quite the same from one summer to the next.
Tanabata is built on the story of two star-crossed lovers separated by the Milky Way, and people traditionally write wishes on slips of paper and tie them to bamboo branches. Walking the arcade means looking up more than ahead, and it is easy to combine with a meal in the neighborhood’s small restaurants afterward.
Koenji Awa-odori
The Koenji Awa-odori Dance is held over two days during a weekend in late August, and it is the loudest night of the month. Troupes called ren move down the streets in rows, women in sloping straw hats and men in short happi coats, to a beat of drums, flutes and shamisen that pulls you along. Around 10,000 dancers take part.
A million spectators line the route, so watching is a standing, shoulder-to-shoulder affair. The dance comes from Tokushima on Shikoku, where the Awa Dance Festival runs from 12 to 15 August, and Koenji’s version brings that southern tradition into a Tokyo neighborhood of record shops and izakaya, the casual pubs that stay open late.
Fukagawa Hachiman and the water-splashing festival
During the Fukagawa Hachiman Festival, spectators splash water on the people carrying the mikoshi, the portable shrines, which earned the event its nickname, the water-splashing festival. In a month this hot, the logic is easy to see. Bearers shoulder the heavy shrine through the streets, and onlookers with buckets and hoses soak them as they pass.
This is a festival to watch with the expectation of getting wet. Wear clothes that dry quickly, protect your phone, and treat the splashes as part of the show. The shouting, the rhythm of the carriers and the spray make it one of the most physical ways to see a Tokyo tradition in motion.
Food in August is built around cold dishes. Soba and somen noodles arrive on bamboo trays with a dipping sauce, shaved ice comes drizzled with fruit syrup or green tea, and edamame, cold beer and grilled skewers fill the izakaya tables. Barley tea served chilled is the drink at nearly every meal, and watermelon shows up at festival stalls and in convenience stores.
Between festivals, the day suits indoor and shaded outings: museums in Ueno, the covered streets of Asakusa, department store food halls in the basement, and the wooded grounds of shrines like Meiji Jingu. Urban shops are generally open from 10:00 a.m. to 8:00 p.m. every day, so an air-conditioned browse is always an option on a heavy afternoon.
Mount Fuji’s climbing season typically runs from the beginning of July to about the first week of September, so August falls inside it. Travelers drawn to the mountain should know the season is a defined window and that trails are closed from the upper stations in winter.
A two-day itinerary for Tokyo in August
Day 1 starts in the east of the city with Senso-ji in Asakusa, the temple approached through the Nakamise shopping street, with its incense smoke and paper lanterns. Walking the covered lanes around the temple gives you some shade, and a stall of cold, sweet snacks is never far. Eat lunch at a soba shop, where chilled noodles with a dipping sauce suit the weather.
In the afternoon, move to Ueno and spend the hottest part of the day inside its museums, with Ueno Park around them for a slow stroll afterward. In the evening, head for a festival: Asagaya in early August for the lit-up Tanabata arcade, or Koenji on the late-August weekend for the dance. End with grilled skewers and cold beer at a neighborhood izakaya.
Day 2 begins in the west at Meiji Jingu, a shrine set in a wooded park where the trees take the edge off the heat. From there, walk into Harajuku for fashion shops and crepe stands, then continue to Shibuya for lunch and its crossing. A noodle shop or a department store restaurant floor keeps the middle of the day indoors.
Spend the afternoon in Shinjuku, which is Tokyo’s administrative center, among department stores, bookshops and the tall hotels of the west side. At night, look for a bon-odori in a nearby shrine or park, which happen from mid to late August, or settle into the lanes of small bars. If the sky opens, the rain plan is museums, covered arcades and the food halls beneath the department stores.
Is Tokyo busy in August?
Tokyo is a lively city in August, but the energy comes from festivals and evening events rather than from the sights themselves. The shape of the month is set by Obon, when people return to ancestral family places to honor their ancestors and clean their graves, which changes the rhythm of the city for those days.
The biggest crowds are tied to specific events. The Koenji Awa-odori brings a million spectators over one weekend, and the neighborhood streets around the route fill accordingly. Asagaya’s Tanabata arcade and the bon-odori sites are the other places where you will find people shoulder to shoulder in the evening.
Day to day, urban shops are generally open from 10:00 a.m. to 8:00 p.m. every day, so shopping and department store browsing carry on through the month. The pace of the day tends to move toward the evening, when dances, stalls and izakaya take over, and the heat shapes everyone’s schedule, residents included.
What to pack for Tokyo in August
Pack for heat, humidity, sudden showers and a lot of walking at night. These items cover most of what the month asks of you:
- Light, quick-drying clothes, because humidity keeps cotton damp and the Fukagawa water-splashing can soak spectators.
- A compact umbrella, since August rain tends to arrive in heavy bursts.
- A small towel or handkerchief for your neck, which suits long evenings at outdoor festivals.
- A thin layer for air-conditioned trains, museums and stores.
- Comfortable walking shoes for temple grounds, arcades and festival streets.
- A refillable bottle for the long, hot days between stops.
Good to know before you go
Summers on Honshu are very humid, hot and sultry, and in Tokyo that sets the tone for the whole month. Plan the day in two halves, with outdoor sights and walks around the edges and museums, department stores and cafés in the middle. Festival dates shift from one year to the next, and some, like the Koenji weekend, are held only over two days, so build the trip around them rather than the other way around.
Urban shops are generally open from 10:00 a.m. to 8:00 p.m. every day, which leaves room for evening shopping. Rural areas often close earlier, sometimes as early as 6:00 p.m., which matters if you plan an excursion beyond the city.
Tokyo in August vs July and September
Moving the trip four weeks earlier puts you in July, with longer evenings and more rain days, and Yasukuni Shrine’s Mitama Matsuri in the middle of the month. The Fuji climbing season is also under way, and July is the first of the two months in that window that you would share with August. You trade August’s bigger sunshine total for a slightly cooler afternoon.
Moving four weeks later takes you into September, when the highs ease, the daylight shortens and the rain total is the largest of the three months, so showers come on more days. The Obon dances and the Koenji weekend are behind you, and the Fuji climbing season ends on September 10th. The festival atmosphere of August gives way to a calmer city.
Choose July if you want Mitama Matsuri and longer daylight, August if you want the dances, Tanabata and the most sunshine, and September if heat and humidity are what you least want to meet.
Is August a good time to visit Tokyo?
August is a good time to visit Tokyo for travelers who enjoy festivals, evening life and summer food, and who can take heat and humidity in stride. It suits people who want to join a bon-odori, watch Koenji’s drummers or walk the Tanabata arcade, and who are happy to spend the middle of the day in museums and stores.
It is a harder month for anyone who wants long walks outdoors, or who dislikes sticky air and sudden showers. Those travelers would do better in a cooler month, when sightseeing does not depend on air conditioning.
On arrival, check which festival falls closest to your dates, since the evening dances are the reason to come, and then fill the days around it. August’s character is its neighborhood matsuri, where a covered shopping street, a shrine ground or a closed-off road becomes a stage for drums, paper lanterns and a ring of dancers moving in circles.
