What Is the Weather Like in Japan in August? Heat, Humidity and Typhoons
Japan in August Temperature: How Hot is Japan in August?
August is the hottest month of the year, with sustained high temperatures and a constant risk of typhoons.
The average Japan in August temperature is about 31°C (88°F) during the day and a minimum of 24°C (75°F) at night. The humidity often soars above 80%, making the heat feel even more oppressive!
This is especially true in urban areas, where "tropical nights" (temperatures not dropping below 25°C or 77°F) are common.
Typhoon & Rainfall in Japan in August
The weather can be quite complex in August, and you'll need to pay close attention to the forecast for sudden downpours and typhoons.
Afternoon Showers: Due to the heat and humidity, sudden, localized thunderstorms can pop up in the afternoon. They pass quickly but can be very heavy.
Typhoon Rain: August is a peak month for typhoon season. Typhoons can bring heavy, sustained rainfall and strong winds, which may cause flooding and landslides.
Frontal Rain: Sometimes, a stagnant front can bring several days of continuous heavy rain, especially on the Sea of Japan side.

Regional Differences in August Japan
Given Japan's long, narrow geography, the Japan in August weather can vary significantly by region.
| Region | Weather Feature | My Travel Tips |
|---|---|---|
| Hokkaido | Relatively cool and dry, with average temperatures of 20-25°C. | A perfect summer escape! Pack a light jacket for cooler mornings and evenings. |
| Honshu (Tokyo, Osaka, Kyoto) | Hot and humid, with highs of 30-35°C. Afternoon showers are common. | Stay hydrated! Plan your outdoor activities for the morning or late afternoon to avoid the midday heat. |
| Okinawa | Hot, with an average of 31°C, but sea breezes offer some relief, around 29°C. | A great time for a beach vacation, but keep a close eye on typhoon forecasts. |
| Mountains (Mt. Fuji, Japan Alps) | The higher the altitude, the lower the temperature (e.g., Mt. Fuji's midpoint is about 15°C). | You'll need professional gear for climbing. Pack warm, waterproof layers as nights can drop to 5-8°C at the summit. |
Is the Weather in Japan in Late August (Aug 21-31) Better?
The heat usually persists in Japan in late August, especially in cities.
However, the risk of multi-day heatwaves (above 35°C) might begin to subside, though it's still a long way from the cool days of autumn. You'll still need to take precautions against the heat.
Typhoon risk also remains!
On the bright side, the temperature difference between day and night might start to increase slightly, especially in northern and highland areas, making the evenings a little more comfortable.

1. Obon Festivals & Dances: A Must-Do in Japan in August
The Obon Festival is the soul of a Japanese summer. It's a national holiday dedicated to honoring ancestors, but for us, it's also a big party!

On summer nights, massive fireworks displays (Hanabi Taikai) light up the sky. These are an expression of both romance and energy!

Dress up in a yukata and find a spot by a river or harbor, and you've got a memory you'll never forget.

August is a peak domestic travel season due to school holidays and the Obon Festival, when many Japanese people travel back to their hometowns.
Here's how to navigate the crowds and still have a great trip:
Don't Wait Until the Last Minute, especially for travel between cities. Book your Shinkansen bullet trains, flights and hotels as soon as your travel plans are finalized!
Avoid Long-distance Travel During the Obon Festival! The days immediately before and after the Obon holiday (roughly August 13-16) are the busiest for trains and airports.
Visit Less-Crowded Regions: While major cities will be packed, consider visiting a quieter destination, such as Kamikochi or Kumano Kodo hiking trails or Karuizawa, a highland resorts.
Adjust Your Daily Schedule: Visit popular sights, like temples or castles, either right when they open in the morning or just before they close in the evening. This lets you see them with fewer people and in cooler temperatures.
