By RitaUpdated Aug. 23, 2023

August marks the end of Japan's summer (June to August). Average daily temperatures peak at 31°C (88°F). If you'd like to escape the heat, northern Japan and the Japanese Alps are ideal destinations.

Despite the heat, you'll be rewarded with the driest weather of summer in Japan, with just a few short downpours, as the rainy season (June to August) fades away and the typhoon season (September/October) is yet to arrive.

You could also enjoy world-class fireworks displays and abundant Nipponese festivals in August.

Tokyo and Central Japan in August: Hot but Best for Mountain Climbing

Seeing Mt.Fuji from Hakone Seeing Mt.Fuji from Hakone

August is the hottest month in central Japan, averaging 31°C (88°F) at maximum. Its average rainfall is moderate at 147 mm (6 inches), and occasionally comes as afternoon downpours.

August is a good time for mountain-climbing expeditions, like up Mount Fuji or the Japanese Alps. You'll experience cooler temperatures, fresh air, and dense forests in the mountains.

When travelling in central Japan, the heat actually wouldn't bring too many problems. You could enjoy plenty of indoor activities inside air-conditioned buildings and travel in a private air-conditioned car, which is also helpful to minimize the inconvenience/discomfort of any rainfall.
