Japan Rainy Season Guide
Tsuyu Dates · Hydrangeas · Indoor Picks · Packing Tips
Japan's rainy season — tsuyu (梅雨), literally "plum rain" — is one of the country's most misunderstood travel periods. Yes, it rains more. But it also means cheaper hotels, fewer crowds, and some of the most beautiful scenes Japan offers: misty bamboo groves, hydrangea-lined temple paths, and golden pavilions reflected in rain-slicked stone. With the right mindset and a good umbrella, tsuyu is one of Japan's most rewarding seasons to visit.

Why Rainy Season is Underrated
💰
Lower Prices
Hotels in June are often 20–40% cheaper than May or July. The unpopular season is your best chance at value bookings.
👥
Fewer Crowds
Popular spots like Kinkakuji, Arashiyama, and Fushimi Inari are noticeably quieter. No queuing at attractions.
💧
Hydrangeas
Japan's ajisai (hydrangea) season peaks in June — blue, purple, white, and pink blooms cover temple paths, hillsides, and railway lines.
🌿
Green & Lush
Gardens are at their most vivid green. Temple moss gardens in Kyoto (Saihoji, Ryoanji) are spectacular after rain.
♨️
Onsen Season
There's nothing better than a covered rotenburo (outdoor bath) in the rain. Hakone, Kinosaki, and Arima are perfect.
🏛️
Museum Weather
Perfect excuse for teamLab, Tokyo National Museum, the Ghibli Museum, and Osaka's incredible Museum of Natural History.
Best Hydrangea Viewing Spots
Meigetsuin Temple (明月院)
📍 Kamakura
🌸 Peak: Mid–late June
Known as the "Temple of the Blue Hydrangea" — 2,500 hydrangea plants of a rare blue variety line the path to the main hall. Stunning circular window framing the rear garden.
Hakone Tozan Railway (箱根登山鉄道)
📍 Hakone
🌸 Peak: Mid-June to early July
Over 10,000 hydrangea plants line the mountain railway. The train runs after dark so blooms are illuminated against the night sky — a spectacular effect unique to Hakone.
Fushimi Tsurunomichi (伏見つるのみち)
📍 Kyoto
🌸 Peak: Late June
A quiet walking path near Fushimi Inari lined with hydrangeas. Far fewer crowds than tourist trails — a local's secret for tsuyu season in Kyoto.
Hakusan Shrine (白山神社)
📍 Tokyo (Bunkyo)
🌸 Peak: Mid-June
A neighborhood shrine famous for its hydrangea festival (Ajisai Matsuri) in June. Free entry. Vendors sell local food and crafts — a charming local experience.

Frequently Asked Questions
When is the rainy season in Japan?+
Japan's rainy season (tsuyu or baiu, 梅雨) varies by region. It typically begins in Okinawa around mid-May, moves to Kyushu and western Japan in early June, reaches Tokyo and central Honshu by early-to-mid June, and ends around mid-July for most of Japan. Hokkaido does not have a distinct rainy season.
Is it worth visiting Japan during the rainy season?+
Yes — Japan's rainy season has real advantages. Hotels are cheaper (often 20–40% less than peak season), crowds are smaller, and Japan is strikingly beautiful in the rain. Hydrangea blooms are at their peak in June, misty temple gardens look stunning, and traditional buildings like Kinkakuji and Nanzenji feel more atmospheric without tourist crowds.
What is the best thing to do in Japan during the rainy season?+
The rainy season is ideal for museum days (Tokyo National Museum, teamLab, Ghibli Museum), indoor onsen (rotenburo covered baths), exploring covered shopping arcades (shotengai), watching the rain from a temple veranda, and spotting hydrangea (ajisai). Popular hydrangea spots include Hakone Tozan Railway, Kamakura's Meigetsuin (Temple of the Blue Hydrangea), Osaka's Hakusan Shrine, and Kyoto's Fushimi area.
Does it rain all day during Japan's rainy season?+
Not necessarily. The rainy season brings more frequent rain but does not mean constant downpour. Many days have morning or evening showers with dry spells in between. The pattern tends to be overcast mornings, possible afternoon rain, and occasional sunny breaks. Typhoons can bring heavy rain, but typhoon season peaks in August–October, after tsuyu ends.
What should I pack for Japan's rainy season?+
Pack a compact folding umbrella (100-yen shop umbrellas are fine, but a quality folding one is worth it), a light waterproof layer or poncho, waterproof shoes or sandals that can handle wet pavement, and a dry bag for electronics. Plastic umbrella bags (available at every entrance) protect floors — stores and temples provide them freely.
Where is the best place to see hydrangeas in Japan?+
Top hydrangea spots include: Meigetsuin Temple in Kamakura (100,000 plants, best in mid-June), Hakone Tozan Railway (blooms light up at night), Hakusan Shrine in Osaka (free entry), Fushimi area in Kyoto, and Takahata Fudoson in Tokyo. Bloom timing varies by altitude and region — track with JMA's ajisai forecasts in June.
