Surviving Tokyo’s Summer Heat: Essential Tips for Travelers

In recent years, Tokyo’s summers have become increasingly hot. The urban heat island effect has caused temperatures in the city to rise even further. For overseas visitors, adapting to such heat can be challenging. This article will provide detailed information on the current state of Tokyo’s heat and offer effective strategies to cope with it.


Current State of Tokyo’s Heat

Tokyo’s summer lasts from June to September, with July and August being particularly scorching. During these months, it is not uncommon for temperatures to exceed 35°C (95°F) during the day, and the heat often lingers into the night. The summer of 2023 saw record-breaking heat, with frequent heatstroke alerts issued by the Japan Meteorological Agency. These alerts are given on days when the risk of heatstroke is high, especially for the elderly, children, and those in poor health.

The abundance of high-rise buildings and asphalt in Tokyo means that heat is retained throughout the day and into the night, leading to what is known as “tropical nights.” These conditions can result in sleep disturbances and other health issues.

The Importance of Heat Countermeasures

Taking measures to beat the heat in Tokyo is crucial for maintaining health and comfort. Here are some effective strategies:

  1. Stay Hydrated
    • Tokyo’s summer humidity can lead to excessive sweating and dehydration. It is important to drink water regularly while out and about. Sports drinks or oral rehydration solutions can help replenish electrolytes effectively.
      Convenience stores and vending machines make it easy to buy drinks, so be sure to always carry one with you.
  2. Avoid Direct Sunlight
    • Try to avoid direct sunlight during the hottest parts of the day (10 AM to 3 PM). Wearing a hat, using an umbrella, and wearing sunglasses can protect you from the sun. This is particularly important in Tokyo, where many attractions are outdoors.
  3. Wear Appropriate Clothing
    • Choose lightweight, breathable fabrics that dry quickly when you sweat. Clothing with UV protection can also help shield you from harmful rays.
  4. Use Cooling Products
    • Cooling towels, portable fans, and cooling sprays can help you stay cool while on the go. These items are easily available at convenience stores and drugstores throughout Tokyo.
  5. Keep Indoor Spaces Cool
    • Use air conditioning to maintain a comfortable indoor temperature. Combining air conditioning with fans can increase efficiency. Keeping curtains or blinds closed during the day can also help block out the sun.
  6. Plan Sightseeing Wisely
    • Plan to visit tourist spots in the early morning or late afternoon when it’s cooler. This allows you to enjoy sightseeing while avoiding the peak heat.

Heat Measures for Popular Tokyo Attractions

Tokyo has many tourist spots, each requiring different heat strategies. Here are some tips for staying cool at popular destinations:

  1. Asakusa
    • With outdoor attractions like Sensoji Temple and Nakamise Shopping Street, it’s important to wear a hat or use an umbrella and stay hydrated. Take breaks at air-conditioned cafes or the Asakusa Culture and Tourist Information Center.
  2. Ueno
    • Ueno Zoo and Ueno Park offer large outdoor areas. Utilize the shade from trees and take breaks at indoor museums and galleries in the area to stay cool.
  3. Odaiba
    • This waterfront area benefits from breezes but can be very sunny. Combine visits to indoor attractions like Decks Tokyo Beach and Odaiba Marine Park with outdoor activities.
  4. Shinjuku and Shibuya
    • These central areas are great for shopping and dining. There are many air-conditioned malls, department stores, and cafes where you can take breaks from the heat.


Tokyo’s summers are extremely hot, but with proper measures, you can enjoy your visit comfortably. By understanding the heat conditions and using the strategies outlined above, overseas visitors can ensure a safe and pleasant stay in Tokyo. Enjoy your trip and stay cool!
