Japan in Summer and Autumn: Best Times, Festivals, and What to Expect
Japan in autumn is, in my opinion, the best time to visit the country. The heat breaks, the skies clear, the countryside turns spectacular shades of red and gold, and the crowds – while still present – are less suffocating than cherry blossom season.
Japan in summer is… a different experience. It is hot. Genuinely, relentlessly hot and humid in a way that catches most Westerners off guard. But it is also the season of festivals – some of the most incredible cultural events in Japan happen between June and August. If you know what you are getting into and plan for the conditions, summer can be unforgettable.
This guide covers everything about visiting Japan from June through November: weather month by month, the major festivals, what to pack, regional differences, and how to avoid the worst crowds.

Month-by-Month Weather Guide
June: Rainy Season (Tsuyu)
June marks the beginning of the rainy season (tsuyu or “plum rain”) across most of Japan. It is not tropical downpours – it is more like weeks of persistent grey drizzle punctuated by occasional heavier rain. The humidity climbs and everything feels damp.
Temperature: 18-26°C (64-79°F) in Tokyo. Cooler in Hokkaido.
Rainfall: High and consistent. Pack a compact umbrella.
Crowds: Lower than spring and autumn peak. Some of the best deals on accommodation.
Highlights: Hydrangea (ajisai) season – temples and parks are covered in spectacular purple and blue hydrangeas. Kamakura and the grounds around many Kyoto temples are particularly beautiful in June rain.
Hokkaido is not affected by the rainy season and is actually at its best in June – clear skies, cool temperatures, and lavender fields in Furano blooming in late June/early July.
July: Hot Season Begins
The rainy season ends in most of Japan by mid-July. What follows is an abrupt shift to full summer heat.
Temperature: 25-35°C (77-95°F) in Tokyo and Osaka. Higher humidity makes it feel hotter.
Rainfall: Lower than June, but afternoon thunderstorms are common.
Crowds: School summer holidays start in late July, increasing domestic tourism. Gion Matsuri (Kyoto’s biggest festival) takes place in July – expect significant crowds in Kyoto.
The heat reality: I want to be direct about this. Tokyo in August is brutally hot. The combination of actual temperature, humidity, and urban heat island effect means feeling temperatures of 38-42°C (100-108°F) are not unusual. Heat exhaustion among tourists who underestimate this is a real thing.
What helps: Stay near air-conditioned spaces, visit outdoor attractions in the morning before 10am, carry water constantly, and use the extensive underground shopping arcades in Tokyo for midday movement.
August: Peak Summer
August is the hottest month and also the busiest for domestic tourism.
Temperature: 26-36°C (79-97°F) in most of Japan. Humid.
Crowds: Obon week (mid-August) is one of Japan’s busiest travel periods. See the festivals section below. Train tickets book out, accommodation prices spike, and popular areas are packed.
Highlights: Fireworks festivals (hanabi taikai) throughout the country. These are among the most spectacular fireworks displays in the world – some launch 20,000+ fireworks over a river in a single evening.
Best escape: Head to the mountains or Hokkaido. Nikko, the Japanese Alps, Kamikochi, and the Hokkaido interior are significantly cooler than Tokyo and Osaka in August – often 10°C (18°F) cooler.
September: Transition Month
September is the underrated month. The worst of the summer heat begins to ease from mid-September, but the autumn foliage has not started yet. This means:
Temperature: 22-30°C (72-86°F) early in the month, dropping to 18-25°C (64-77°F) by late September.
Crowds: Significantly lower than August and October-November. Some of the best value accommodation months.
Typhoon risk: September is peak typhoon season. Typhoons occasionally make landfall in Japan and can disrupt travel plans. Check weather forecasts and have flexible booking (refundable accommodation) if traveling in September.
My take: Late September is a wonderful time to visit if you are not set on the foliage. The mountains around Nikko and the Tohoku region start showing early color by late September.
October: Best Month of the Year
October is, in my experience, the best month to visit Japan. The summer heat is gone, the skies are clear, the temperatures are comfortable, and the autumn foliage is beginning (in northern regions and higher altitudes first).
Temperature: 15-23°C (59-73°F) in Tokyo. Perfect walking weather.
Rainfall: Low. October is often the driest month in Tokyo.
Crowds: Moderate, building toward November. Not as bad as April (cherry blossom) or November peak foliage.
Highlights: First autumn foliage appears in Hokkaido (early October), the Japanese Alps, and Nikko. City parks begin showing color by late October.
What to do: Everything. Hiking, temple visits, festivals (there are numerous autumn matsuri), and long days of outdoor sightseeing without sweating through your clothes.
November: Autumn Foliage Peak
November is peak koyo (autumn foliage) season across most of Honshu. Kyoto, Nikko, and the mountains around Tokyo turn spectacular.
Temperature: 9-18°C (48-64°F) in Tokyo. Evenings can be cold.
Crowds: High, especially in Kyoto. November foliage crowds in Kyoto rival cherry blossom season. Book accommodation 2-3 months in advance.
Highlights: Foliage peaks in the following order: Nikko (early to mid-November), Tokyo parks (mid-November), Kyoto (mid to late November), Osaka (late November).
Kyoto in November: Genuinely breathtaking. The combination of temple architecture and autumn foliage is iconic for good reason. But it is also crowded in a way that requires planning. Go early morning (before 8am) to the main temples, have a lunch reservation, and avoid the most tourist-heavy sites on weekends.

Major Summer and Autumn Festivals
Tanabata (Star Festival) – July 7
Tanabata celebrates a mythological meeting between two stars. Streets are decorated with colorful paper streamers and bamboo, and people write wishes on paper strips (tanzaku) to hang on the bamboo.
Major Tanabata celebrations:
– Sendai Tanabata Matsuri (August 6-8): The largest Tanabata festival in Japan, held slightly later than most. The main shopping arcades are covered in massive bamboo decorations.
– Hiratsuka Tanabata Matsuri (July): One of the best in the Kanto region, just outside Tokyo.
Gion Matsuri (Kyoto) – Entire July
The Gion Matsuri is one of Japan’s three great festivals and has been running continuously for over 1,100 years. The entire month of July is technically the festival, but two key events draw the largest crowds:
– Yoiyama (July 16-17): Evening street festival in downtown Kyoto. Hundreds of food stalls, the 32 traditional floats (yamaboko) displayed and lit up, kimono-clad crowds.
– Yamaboko Junko procession (July 17): The main float procession through central Kyoto streets. Incredible to watch but extremely crowded.
Book Kyoto accommodation months in advance if you want to attend Gion Matsuri.
Obon – Mid-August (typically August 13-16)
Obon is the Japanese festival of remembrance for ancestors’ spirits. Families return to their hometowns, temples hold ceremonies, and Bon Odori (traditional circle dances) take place nationwide.
For travelers:
– Transportation (Shinkansen, highways) is at absolute maximum capacity August 10-18. Book months in advance.
– Many shops and restaurants may be closed or on reduced hours in some areas.
– The Bon Odori dances are free to watch and often participate in. Local neighborhood associations hold them in parks and temple grounds.
– Awa Odori (Tokushima, August 12-15): The most famous Bon Odori festival in Japan. Tokushima city is transformed by enormous street dancing processions. Performers and audience members are all encouraged to dance.
Hanabi (Fireworks Festivals) – July to August
Japan’s summer fireworks festivals are astonishing in scale. The largest launch thousands of fireworks from barges over rivers, with crowds of hundreds of thousands watching from the banks.
Major hanabi festivals:
– Sumida River Fireworks (Tokyo, late July): One of the oldest and most prestigious. Around 20,000 fireworks. Enormous crowds – arrive early.
– Naniwa Yodogawa Fireworks (Osaka, August): Around 10,000 fireworks over the Yodogawa River.
– Lake Suwa Fireworks (Nagano, August 15): Over the lake with mountain backdrop – one of the most scenic in Japan.
Tickets for premium viewing areas are sold through Klook and ticket agencies. Free viewing is available from public areas nearby.

Autumn Leaves (Koyo) – October to November
Koyo is not a festival in the traditional sense, but it functions as one – entire tourist ecosystems exist around tracking and viewing the foliage. Japan has detailed forecast maps (koyo maps) similar to cherry blossom forecasts, showing where peak color will occur week by week.
Top koyo destinations:
– Nikko (Tochigi): Famous for brilliant color against mountain temple architecture. Peak: late October to early November.
– Kyoto (various temples): Tofuku-ji, Eikan-do, Arashiyama. Peak: mid to late November.
– Arashiyama (Kyoto): Bamboo grove + autumn leaves. Peak: mid-November.
– Hokkaido: Goes first – Sounkyo Gorge and Daisetsuzan National Park peak in early-mid October.

What to Pack by Season
Summer (June-August)
– Lightweight, breathable clothing: Linen, technical fabrics, light cotton. Avoid denim in August – you will regret it.
– Multiple layers for indoor spaces: Japanese air conditioning is aggressive. You will be sweating outdoors and freezing in restaurants and convenience stores.
– Compact umbrella: Essential for June rain and July-August afternoon storms.
– UV protection: Hat, UV-blocking sunscreen (Japanese sunscreen is excellent – buy more here), and UV-protective arm covers (you will see Japanese people wearing these – they are practical, not just a fashion statement).
– Cooling towels and spray: Mist spray bottles and cooling towels are sold everywhere in Japan for summer and are genuinely helpful.
– Comfortable, breathable shoes: You will walk 15,000+ steps per day. Sandals are fine for casual days. Sneakers in a breathable fabric for temple visits.
Autumn (September-November)
– Layers: October requires light layers (t-shirt + light jacket). November needs a proper mid-weight jacket.
– Comfortable walking shoes: Trails and temple steps are common in koyo areas.
– Small backpack: For day trips to foliage spots.
– One warm layer for evenings: Kyoto in late November evenings can be 5-8°C (41-46°F).

Tips for Avoiding Crowds
Go early: Most tourists arrive at shrines and parks between 9am and 12pm. Arriving at 7am means you will often have famous sites nearly to yourself.
Avoid Golden Week and Obon: These are the two most congested travel periods in Japan. If you have schedule flexibility, avoid mid-August and the Golden Week period (late April-early May).
Consider lesser-known spots: Kyoto’s famous sites like Kinkaku-ji are packed in November. Temple complexes like Shorin-in and Komyo-ji in the same season are equally beautiful and far less visited.
Use weekdays: Weekday visits to any popular site are noticeably less crowded than weekends, especially in October and November.

Final Thoughts
There is no bad time to visit Japan, but there are better-informed times. Summer rewards the bold – those willing to endure the heat for access to festivals and events that are unlike anything else in the world. Autumn rewards the planner – book ahead, go early, and you will experience some of the most beautiful seasonal scenery on earth.
My honest advice: if this is your first Japan trip and you have flexibility, aim for early to mid-October in Tokyo and then early-to-mid November as you move toward Kyoto. You will get perfect weather in Tokyo and peak foliage in the Kansai region.
