What to Expect from Japan’s Summer Weather: A Guide for Visitors to Osaka

As summer approaches, visitors to Japan—especially those staying in Osaka—can look forward to a vibrant season filled with festivals, fireworks, and delicious seasonal foods. However, Japan’s summer also brings unique weather conditions that may surprise first-time travelers. Here’s what to expect and how to prepare.

Hot, Humid, and Full of Energy

Summer in Osaka typically begins in June and peaks in July and August. Temperatures can reach between 30°C to 35°C (86°F to 95°F), and humidity levels are quite high. While this might feel intense, it’s all part of the Japanese summer experience. Locals often carry small fans or cooling towels, and convenience stores sell refreshing drinks like Pocari Sweat and mugicha (cold barley tea) to help you stay hydrated.

The Rainy Season: Tsuyu

June marks the beginning of the tsuyu or rainy season, lasting about three to four weeks. Expect frequent showers, especially in the afternoons. It’s a good idea to carry a compact umbrella and wear breathable, quick-drying clothing. Luckily, even during the rainy season, the rain doesn’t usually last all day, and there are still plenty of chances to explore the city.

Summer Festivals and Fireworks

Despite the heat, summer is one of the most exciting times to be in Japan. From late July through August, the Kansai region comes alive with festivals like the Tenjin Matsuri in Osaka and spectacular fireworks displays along the rivers. Be prepared for crowds, but also for an unforgettable cultural experience. Light cotton yukata (summer kimono) are popular to wear during these events—and make for great photos too!

Staying Cool at Your Home Base

At Apollo Properties, our furnished apartments and share houses are equipped with air conditioning, so you can relax and cool down after a day of exploring. Whether you’re working, studying, or just here to enjoy the season, we provide comfortable spaces to make your stay enjoyable, even in the hottest months.

Final Tips

Stay hydrated and wear sunscreen.
Avoid being outside during peak heat hours (12pm–3pm).
Enjoy seasonal summer foods like kakigori (shaved ice), somen noodles, and cold tofu.
