Pick a month for Japan as a whole, or a place for all twelve months. Every page gives the JMA's 1991–2020 averages, what to wear by our rules, holidays, how full hotels were in 2025 and what's on that month.
Average high in °C for 1991–2020 (JMA). Each number opens that place's page for that month.
We set the level from the JMA's average daily high for the month, then add items from the average low, wet days and snow. These are our own rules, not the JMA's.
| Level | Average high | What to wear |
|---|---|---|
| Hot | 30°C or more | Short sleeves and light, breathable clothes. A light layer for cold air-conditioning on trains and in shops. |
| Warm | 25 to 30°C | Short sleeves or thin long sleeves, with a light layer for air-conditioning and evenings. |
| Mild | 20 to 25°C | Long sleeves, or a T-shirt with a light jacket or cardigan. |
| Cool | 15 to 20°C | Long sleeves with a light jacket or sweater. |
| Chilly | 10 to 15°C | A warm jacket or light coat over a sweater. |
| Cold | 5 to 10°C | A winter coat over layers, and a scarf. |
| Freezing | under 5°C | A heavy winter coat (down or similar), thermal underwear, a hat, gloves and a scarf. |
Each place uses the JMA station in or nearest to it. Averages are the JMA's normals for 1991–2020.

January has the lowest average high in all 14 of our places with temperature records, and August has the highest in 13 of the 14 (JMA, 1991–2020).
In 2025, April had the most arrivals (3,909,128) and February the fewest (3,258,491) (JNTO).
In an average year (1991–2020) the JMA puts the rainy season at around 10 May to 21 June in Okinawa, 6 June to 19 July in Kinki (Kyoto and Osaka) and 7 June to 19 July in Kanto-Koshin (Tokyo).
Typhoons come within 300 km of Japan most often in August (3.3 in an average year) and September (3.3); 11.7 do so in an average year (JMA, 1991–2020).
The JMA's sample trees open on average from 22 March in Fukuoka to 1 May in Sapporo (1991–2020). In Naha the JMA watches a different species, the Taiwan cherry, which opens around 16 January.
