June is Japan’s rainy season (tsuyu or baiu). Regular rainfall, high humidity, and grey skies are the norm for most of Honshu from early June to mid-July. But June also has lower crowds than any other month outside of winter, excellent prices, hydrangea blooms at their peak, and a uniquely atmospheric Japan that many experienced visitors prefer to the tourist-heavy spring.
Quick Answer: Japan in June: Warm (22 to 28 degrees) but humid and frequently rainy. Tsuyu (rainy season) runs from approximately June 5 to July 19 in Tokyo. Lowest tourist crowds outside of winter months. Hydrangea (ajisai) season at its peak. Budget prices and available accommodation throughout. See the Japan rainy season guide for the complete rainy season guide.
Japan Weather in June
Tokyo
Highs of 24 to 28 degrees. Lows of 18 to 21 degrees. Humidity rises significantly. Rain falls on approximately 12 to 15 days in June. The rain tends to fall in steady periods rather than as an all-day drizzle, with dry windows in between. A compact umbrella is essential throughout June.
Kyoto and Osaka
Slightly warmer than Tokyo. Highs of 25 to 29 degrees. High humidity. The rainy season is felt strongly in Kyoto and Osaka; however, the moss gardens of Saihoji and the bamboo of Arashiyama are particularly beautiful in the June rain. The best time to visit Kyoto depends on the season.
Hokkaido
Excellent in June. Hokkaido is outside the tsuyu zone and has some of its best weather in June: temperatures of 18 to 22 degrees, low humidity, and clear days. Lavender season at Furano begins in late June. See the Hokkaido 7 days.
Okinawa
Okinawa’s rainy season ends in mid-June, earlier than the mainland. From mid-June, Okinawa has excellent beach conditions. See the Okinawa guide.
What to Pack
A compact fold-up umbrella is non-negotiable. Light, moisture-wicking clothing for the humidity. A waterproof layer for heavier rain days. Comfort shoes that handle wet pavements. See the Japan packing guide.
Rainy Season Realities
The tsuyu gets a worse reputation than it deserves. It does not rain continuously: Japan’s rainy season brings periods of grey skies and rain separated by dry, clear windows. Many June trips to Japan experience perfectly manageable weather. The key facts:
- The rain typically falls in frontal systems that pass in 12 to 24 hours
- There are usually several clear, dry days per week in June
- Indoor attractions (museums, teamLab Planets, Universal Studios Japan guide) are particularly good June activities
- The Japan convenience stores guide stocks excellent ponchos and disposable umbrellas at a low cost

Hydrangea Season
Japan’s hydrangea (ajisai) season peaks in June and is one of the most beautiful but less-visited seasonal spectacles in the country. Key hydrangea spots:
Meigetsuin Temple, Kamakura
Known as the ‘Hydrangea Temple’, Meigetsuin in Kamakura has 2,500 blue hydrangea plants that peak in mid-June. See the Kamakura guide for how to visit Kamakura as a day trip from Tokyo.
Meigetsu-in and Hasedera, Kamakura
Multiple temples in Kamakura have significant hydrangea gardens that bloom simultaneously in June.
Hakone
The hillside gardens and woodland paths around Hakone have hydrangeas in bloom throughout June. See the Hakone guide.
Why June Can Be a Great Time to Visit Japan
The combination of lower international tourist crowds, budget accommodation availability, hydrangeas, and excellent conditions in Hokkaido makes June an underrated time to visit Hokkaido. If you prioritize avoiding crowds over avoiding rain, June is one of Japan’s most rewarding travel months.
