June marks the start of Japan's rainy season, known locally as the 'Tsuyu(plum rain)'. Temperatures continue to climb, with most major cities averaging between 19 and 28 °C (66 and 82°F), and humidity becomes increasingly noticeable.
Although the rain nourishes lush greenery and vibrant hydrangeas, it typically falls as light showers or brief downpours, rather than sustained rainfall. This also means fewer crowds and more opportunities to explore many lesser-known attractions.

Facts about June Weather in Japan 2026
Rainfall & Humidity
Expect more frequent showers, which can be sudden and intense.
Exploring the city is made easier if you carry a compact umbrella or a light raincoat.
Don't let the rain put you off — many travelers find that it adds to the charm of temple gardens. Indoor attractions, such as museums or teahouses, are perfect places to retreat to in the afternoon.
Typhoon Concerns
Although June is not peak typhoon season, storms can still occur. It is wise to keep an eye on local forecasts.
In practice, however, disruptions are rare and most itineraries continue as planned.
Heat and sunshine
Some visitors worry that Japan in June might be hot. Although it's not yet the height of summer, you should still prepare for warm days, intense sunshine, and high UV levels.
Make sure you stay hydrated and take short breaks in shaded areas.
Protect your skin with sunscreen, sunglasses, and a hat.
Plan your day carefully: schedule indoor activities or shopping in air-conditioned malls during the hottest hours, then enjoy outdoor or water activities later on.
2. Best Things to Do in June in Japan 2026
Enjoy Hydrangea Season
June is when Japan's famous hydrangeas (ajisai) burst into bloom.
They can be found at temples such as Meigetsu-in in Kamakura and Mimuroto-ji in Kyoto, where the paths are lined with thousands of blooms in shades of blue, purple, and pink.
Visiting these gardens right after it rains makes the colours even more vivid.
The Bunkyo Hydrangea Festival is held every June at Hakusan Shrine and the surrounding park in Tokyo, where more than 3,000 hydrangea bushes create a colourful sea of flowers. There are also food stalls, local performances, and a festive neighbourhood atmosphere.
It's a chance to experience the beauty of the blooms and the charm of a traditional Japanese festival. The event is scheduled to return in June 2026, so travellers can look forward to enjoying this seasonal celebration once again.
Explore Temples and Shrines Without Crowds
Since June falls between the cherry blossom season and the summer holidays, iconic sites such as Fushimi Inari in Kyoto and Senso-ji in Tokyo tend to be less crowded. This 'off-season' atmosphere means you can take quieter photos, enjoy slower walks, and appreciate the surroundings more.
Discover June's Hidden Gems in Japan
In Hokkaido, the weather is mild and the rainy season starts later. It's perfect for hiking around Furano's rolling hills or the flower fields of Biei.
Hokkaido is less affected by the rainy season, so if you want to avoid rain altogether, this region is your safest choice.

In the south, Okinawa's beaches are still quiet before the summer wave of tourists arrives, offering serene island time.
The rainy season in Okinawa typically ends in late June, making it a perfect moment to enjoy the first authentic taste of summer sunshine and laid-back island vibes.
This is also the season to go snorkeling, diving in crystal-clear waters, or hopping between smaller islands for a more off-the-beaten-path adventure.

June is also fantastic for cycling through wide-open farmland, relaxing and healing in outdoor hot springs, or tasting fresh dairy and seafood in local markets.
You might be wondering whether hot springs are only for the cold seasons. In fact, you can enjoy an outdoor onsen experience in June.
During the rainy season, when temple gardens and mountain forests turn lush and green, soaking in an open-air bath feels refreshing rather than stifling.
You can sit in warm mineral waters, surrounded by vibrant summer foliage, with mist rising from the hills and raindrops gently tapping the surface.
In places like Hakone or Nikko, the contrast between the warm water and the humid summer air creates a soothing balance. Meanwhile, in Hokkaido's highland resorts, the cooler breezes make June onsen baths particularly pleasant.
Plan your ideal itinerary by taking a look at the following sample tour packages featuring summer outdoor hot springs (onsen):
7 Days Fukuoka - Itoshima - Kumamoto - Mt.Aso - Kurokawa - Yufuin - Beppu Tour
7 days | From $ 3675

Don't let the showers stop you. Visiting an onsen in June is particularly rewarding.
Open-air baths allow you to soak while light rain falls upon lush greenery. Mountain hot springs in Hokkaido or Nagano offer cool, refreshing air, while seaside onsens in Okinawa provide stunning ocean views as the rainy season draws to a close. Urban day spas in Tokyo or Osaka are also perfect for a relaxing break from the humidity.
What's more, consider spending a few cozy hours in museums and aquariums. Once the sky clears, you can hop on the Sumida River water bus near Tokyo Skytree and glide past cityscapes and bridges to enjoy an unforgettable, breezy view of Tokyo from the water.
In June, Japan slows down.
You can wander through hydrangea gardens after a summer shower, taste fresh cherries at local markets, or enjoy a breezy ride on the Sumida River.
The atmosphere is more relaxed, and there are plenty of those little moments that make a trip unforgettable. Would you like someone else to handle the details? Get in touch and we'll organise a fully inclusive private trip, leaving you free to show up and enjoy.

4. Cost & Crowds for Staying in Japan in June 2026
Travelling in June is more budget-friendly than in peak months such as April (cherry blossom season) and August (summer holidays).
On average, hotel rates are 10–20% lower than during peak season, making it easier to find good deals in both major cities and rural areas.
Although there are fewer crowds in June, we recommend booking well in advance to secure the best off-season deals — ideally 3–5 months before your stay — to ensure a smooth and worry-free experience.
5. Q&A about Travelling to Japan in June 2026
Q1: Will I run into big crowds in June?
Not really. June slips between the busy cherry blossom season and the summer rush, so you'll find temples, shrines, and city streets a lot calmer.
Q2: Do hotels sell out quickly?
Most places are easier to book in June, but cosy ryokan in Kyoto or Hakone's onsen resorts can still get busy. A month or two ahead is usually enough to grab good options.
Q3: How much rain should I expect?
It's the start of the rainy season, so light showers and occasional downpours happen. Luckily, they don't last all day—keep a small umbrella handy and you're set.
Q4: Is it already super hot?
It's warm and humid, yes, but not yet the peak summer heat. Think mid-20s°C most days. Drink plenty of water, slow down your schedule, and take a break by popping into an air-conditioned café when needed.
Q5: Why bother visiting in June at all?
That's the best part—it's quieter, more affordable, and full of seasonal treats like hydrangea gardens, fruit picking at Mt. Fuji, and peaceful walks without the crowds.
What We'd Like to Say
June in Japan means:
Warm days with fresh greenery.
Light rain showers that bring out the hydrangeas into full bloom.
Fewer crowds and better hotel deals!
Seasonal activities like fruit picking and relaxing in an onsen
June is a quieter, greener, and surprisingly rewarding time for travellers who want something different from the usual peak seasons.
