August holds the highest average temperatures of the year in Tokyo and Kyoto, both cities regularly into the low thirties by day with heavy humidity, while Hokkaido stays noticeably cooler throughout. The middle of the month carries Obon, a traditional observance for the ancestors that, in practice, empties the cities as families travel to their hometowns, making it the second major domestic travel surge of the year after Golden Week.
the weather
The weather
Tokyo's August days average a high of 31.3°C and a low of 23.5°C. Kyoto runs close to the same figures, 33.7°C by day and 24.7°C overnight, since both cities sit in the same broad climate band despite Kyoto's inland basin sharpening the extremes at either end of the year. Sapporo is a different country: an average high of 26.4°C and a low of 19.1°C, figures from the Japan Meteorological Agency's published climate normals for 1991 to 2020, the thirty-year average against which every year in Japan is still read. Rain follows the same normals: Tokyo averages 154.7 millimetres of precipitation across around 7.4 days with measurable rain in August, while Sapporo's own August total is 126.8 millimetres, mostly as rain by this point in the year.
in season
What is in season
- Obon, observed nationally around the middle of the month, though the exact week is set by local custom rather than a fixed national holiday.
- Fireworks festivals (hanabi) are held across the country through the month.
- Hokkaido's lavender and sunflower fields, around Furano and Biei, are at their fullest.
- Peak heat and humidity hold nationwide, especially inland and away from the coast.
- Summer festivals and matsuri continue in cities and villages throughout August.
beyond the three cities
Beyond Tokyo, Kyoto and Sapporo
Okinawa and Hokkaido sit at opposite ends of August's range: the southern islands hold their highest humidity of the year, while Hokkaido, still noticeably cooler than Honshu, is where the Wild North Tour is placed for exactly that reason. Inland cities such as Kyoto, shielded from any sea breeze, regularly run hotter by day than coastal Tokyo.
closed and crowded
What is closed, and what is crowded
Obon week, generally the week around the middle of August, is the second major domestic travel surge of the Japanese year, comparable to Golden Week: trains and flights book out, and many small family-run businesses close while their owners travel. City centres can, paradoxically, feel quieter during Obon itself, since a large share of residents have left for their own hometowns, though the effect reverses on the trains and roads carrying them there. Opening hours at smaller shops, temples and museums vary enough by day and by property that any single visit is worth confirming the same week, rather than relying on a printed schedule alone.
what to wear
What to wear
The same light clothing as July, with sun protection a clear priority given the intensity of the midday sun. Indoor spaces, trains and museums are all air-conditioned, often strongly, so a light layer is worth carrying for the contrast. Comfortable, easily removed shoes are worth choosing whatever the season, since temples, ryokan and traditional restaurants alike expect shoes off at the door, often several times in a single day.
where the tours run
Where Luxury Japan Travel goes in August
The Wild North Tour of Hokkaido runs through the first ten days of August, to 6 August 2027, at $21,500 per person, with a deposit of USD $3,500 per person and the balance due 95 days before departure. For the remainder of the month, including travel over Obon itself, guests are directed to the Custom Tour of Japan, with no ceiling on the size of the party.

This page is one of twelve, one for each month of the Japanese year, each reporting the same weather, season and closure detail in its own month and linking both of its neighbours in the sequence. August sits between July and September on that calendar, and the full set is gathered in The Japan Edition's Seasons hub.
