Japan’s rainy season — known as tsuyu (梅雨) — typically runs from early June through mid-July across most of Honshu, including Tokyo, Kyoto, and Osaka. While it can dampen outdoor plans, traveling during tsuyu also has its rewards: fewer crowds, lush green landscapes, and the iconic sight of hydrangeas in full bloom.
When Is Japan’s Rainy Season in 2026?
The timing of tsuyu varies by region and year, but here are the typical dates for 2026:
- Okinawa: Early May – Late June
- Kyushu & Shikoku: Early June – Mid-July
- Kansai (Osaka, Kyoto): Early June – Mid-July
- Kanto (Tokyo): Early June – Late July
- Tohoku: Mid-June – Late July
- Hokkaido: No rainy season (one of the best destinations in June!)
Note: Tsuyu doesn’t mean it rains every day — there are often sunny breaks. But humidity is high throughout the season.
What the Weather Is Actually Like
Many first-time visitors imagine non-stop downpours, but the reality is more nuanced. During tsuyu:
- Temperatures range from 20°C to 28°C (68°F to 82°F)
- Humidity is very high — often 80–90%
- Rain tends to fall in bursts, not all day long
- Evenings can be especially muggy
- Sudden heavy downpours are common — always carry an umbrella
What to Pack for Japan’s Rainy Season
Essentials
- Compact folding umbrella — available at any convenience store in Japan for around ¥500–¥800 if you forget
- Lightweight rain jacket or poncho — better than an umbrella for active sightseeing days
- Quick-dry clothing — heavy cotton stays damp for hours in the humidity
- Waterproof sandals or shoes — or at minimum, a spare pair of socks
- Small towel — useful for wiping off after getting caught in rain
Nice to Have
- Anti-humidity hair products (if humidity affects your hair)
- Moisture-absorbing shoe inserts
- A dry bag or waterproof phone case for outdoor activities
Pros of Visiting Japan During Tsuyu
- Fewer tourists: Popular spots like Kyoto’s Arashiyama and Fushimi Inari are noticeably less crowded
- Lower prices: Hotels and flights are cheaper during the rainy season shoulder period
- Hydrangeas (ajisai): Japan’s hydrangeas peak in June — temples and parks are stunning
- Lush greenery: Gardens and mountain scenery are incredibly vivid
- Iris flowers: Many parks hold iris festivals in early June
Best Places to See Hydrangeas (Ajisai) in Japan
Hydrangeas are one of the highlights of the rainy season. Here are top spots to see them:
- Meigetsuin Temple, Kamakura — nicknamed “Hydrangea Temple,” thousands of blue ajisai line the path
- Hasedera Temple, Kamakura — panoramic ocean views with ajisai in the foreground
- Hakone Open-Air Museum — outdoor sculptures surrounded by seasonal flowers
- Bunkyo Hydrangea Festival, Tokyo — 3,000 hydrangeas in the grounds of Hakusan Shrine
- Mimurotoji Temple, Uji (Kyoto) — 10,000 hydrangeas make this one of Japan’s best ajisai spots
Indoor Activities for Rainy Days
Rainy days are a perfect excuse to explore Japan’s world-class indoor attractions:
- Museums: Tokyo National Museum, teamLab Planets, Ghibli Museum (book months ahead!)
- Onsen & sento: A hot spring bath feels particularly luxurious on a rainy day
- Covered shopping streets (shotengai): Many Japanese cities have covered arcade shopping streets — perfect for rain
- Depachika (department store basement food halls): A foodie paradise that never gets old
- Escape rooms & game centers: Popular with locals and tourists alike
- Ramen shops: Nothing beats a steaming bowl of ramen on a rainy afternoon
Getting Around in the Rain
Japan’s public transportation makes rain far less of a problem than in many other countries:
- Trains run reliably regardless of weather (except for very severe typhoon-level events)
- Most major train stations connect directly to shopping malls or underground arcades
- Taxis are easy to find and comfortable during heavy rain (though surge pricing doesn’t apply in Japan)
- Coin lockers at stations are useful for storing wet jackets or umbrellas
Umbrella tip: Japanese convenience stores sell perfectly good umbrellas. Many restaurants and shops also have umbrella stands at the entrance — it’s completely normal to leave your umbrella there while you eat.
Should You Travel to Japan During Tsuyu?
Absolutely — with the right preparation. The rainy season gets a bad reputation, but experienced Japan travelers often enjoy it for the combination of beautiful seasonal scenery, thinner crowds, and lower costs. Just pack light, bring a rain layer, and embrace the mood.
If you’re flexible, Hokkaido is an excellent alternative — it’s warm and dry in June and July while the rest of Japan is damp.
Quick Tips Summary
- Always carry a compact umbrella — buy one at a konbini if needed
- Wear breathable, quick-dry fabrics to manage the humidity
- Visit hydrangea spots in early-to-mid June for peak bloom
- Plan indoor backup activities for each day
- Book accommodation early — even shoulder season spots fill up
- Consider Hokkaido if you really want to avoid rain entirely
