Summer in Japan is both exciting and challenging. With soaring temperatures, high humidity, and the lively atmosphere of festivals, it can feel overwhelming if you are not prepared. Whether you are traveling for the first time or living here long-term, learning how to survive summer in Japan will make your experience comfortable, safe, and memorable.
Understanding Summer in Japan
- Temperature and Humidity: Average temperatures range from 30°C to 38°C in major cities like Tokyo, Osaka, and Kyoto. The humidity makes it feel even hotter.
- Typhoon Season: Typhoons often occur from late July to September, bringing heavy rain and strong winds.
- Peak Season: Summer is also when major festivals (matsuri) and fireworks (hanabi) happen, so expect large crowds.
Knowing these conditions helps you plan your activities and stay safe.
Essential Tips to Stay Cool
1. Hydrate Constantly
Japanese summers can cause heatstroke (熱中症, nechuusho). Always carry water or an isotonic drink such as Pocari Sweat or Aquarius. Convenience stores sell them everywhere.
2. Use Cooling Goods
Japan is full of creative summer survival products:
- Portable fans and handheld mist sprays
- Cooling towels and neck wraps
- UV umbrellas and sun sleeves
These are available at Don Quijote, Daiso, and most drugstores.
3. Dress Light but Smart
Choose breathable fabrics like cotton and linen. Many people use UV protection clothing to block harmful rays. A hat and sunglasses are also essential.
4. Take Advantage of Air-Conditioned Spaces
Shopping malls, train stations, and department stores are not only great for shopping but also for cooling down. In big cities, underground shopping streets are lifesavers.
Food and Drinks for Surviving the Heat
One of the best ways to beat the summer in Japan heat is through seasonal food and drinks:
- Kakigori (shaved ice dessert) – flavored with matcha, strawberry, or syrup.

- Seasonal drinks – iced matcha, mugicha (barley tea), and lemon soda.
These are light, refreshing, and help you stay energized.
