Is September a Good Time to Visit Japan

September is a smart period to visit Japan. It is an ideal month to explore Japan at your relaxing pace: balance both the perfect outdoor temperature and the empty attractions after the summer holiday peak. Just make your flexible itinerary and prepare for the rain.

As the intense summer heat gradually fades, September is the right time to enjoy a comfortable, warm-weather Japan journey with leisure walking and mountain hiking to capture Japan's delicate natural landscape. If you like, it is also possible to catch the first changing colors of autumn foliage in Japan.

City sightseeings also much more comfortable with the crisp air, paired with seasonal harvest ingredients for a refreshing meal. You can find those crowd-free sites for your linger and photography, and take a more immersive tea ceremony with meditation for a deeper cultural discovery. What's more, at relatively lower prices for better rooms and better experiences.

Is September the Autumn Leaves Season in Japan

Yes, September marks the beginning of the autumn foliage season in Japan (late September to mid-December), and in late September, you can see the first autumn colors in Daisetsuzan National Park, Hokkaido.

However, it should be noted that the fall foliage scenery in Japan in September is only a small part and mainly focuses on northern Japan. While looking for those dramatic layers of orange and gold in Tokyo and Kyoto, consider making your autumn Japan journey around late November.

Crowds & Costs of Japan in September

September is a shoulder season for tourism in Japan, and the crowds and prices will be relatively friendly.

With schools back in session and locals returning to work after the summer holiday and Obon Festival, there will be fewer domestic tourists at popular attractions. This means you have a better chance to explore this fantastic country with the advantage of relatively discounted prices for tickets and accommodations.

Note: Silver Week, another public holiday similar to the popular Golden Week, falls from September 19 to 23, 2026. Skip this holiday period if you are looking for a more budget-friendly, relaxing, and crowd-free Japan trip.

Best Places to Visit in September

Hokkaido

September is an ideal time to visit Hokkaido, as you can be among the first to experience Japan's autumn atmosphere. It's harvest season, with golden ears of rice swaying in the wind. You can stroll through vast lavender fields, observe squirrels and birds in the nature park, and pick fresh fruit in the orchards.

Meanwhile, colorful leaves cover the streets and alleys in late September, an ideal time to immerse yourself in the vibrant fall atmosphere at Hokkaido University Ginkgo Avenue and Jozankei Hot Spring.

Also, if the typhoon uncertainty is the thing you worry about, just take the direct way to Hokkaido, which is the least affected (barely any rain or other weather disruption) destination during Japan's typhoon season.

Tokyo

Tokyo is also welcoming during your September journey in Japan. It hosts many festivals to celebrate the arrival of autumn: encounter the spectacular parade of portable mikoshi in the Ikebukuro neighborhood, or take photos with thousands of Cosmos flowers at Showa Kinen Park.

If you are interested in traditional sports in Japan, you can also experience the famous Sumo culture through a simple and relaxing lunch with those former wrestlers, or an exciting live Grand Sumo Tournament performance at Tokyo's Ryogoku Kokugikan.

Note: It is recommended to make your stay here a little bit longer when catching the typhoon; those various indoor activities and convenient transport in Tokyo are really helpful during this special period.

Mt. Fuji

With the pleasant temperature of September, Mount Fuji is ideal for both relaxing and adventure. You can sightsee around the Lake Kawaguchi area first, take a cruise through the mirror-like water surface, or wander through the farmhouse village beneath the sacred Mount.

And the short climb up to the nearby Arakurayama Sengen Park can be more comfortable and easier, a good spot to capture the classic Japanese pagoda and the distant Mt. Fuji. If you prefer something exciting, take the final chance for Mt. Fuji hike before mid-September, the last tail of the Mt. Fuji climbing season.

Book a mountain hut, bring adequate equipment, and climb the popular Yoshida Trail at your own pace. When you arrange the time appropriately, you can even catch the splendid sunrise at the highest peak of Japan.

Kyoto

It is always a good idea to take advantage of the crowd-free atmosphere to explore Kyoto, the former capital of Japan, best for more immersive cultural experiences.

In addition to the iconic Kinkaku-ji with a gold-leaf facade, Fushimi Inari Taisha, famous for its thousands of vermilion torii, you can also put on a kimono or yukata at the Gion area for a stroll and take memorable photos. Then take part in the tea ceremony at wooden tea houses, follow the geisha lady to make your own matcha tea and desserts.

If possible, add authentic Kaiseki cuisine to your dinner, enjoy those dishes based on fresh fall vegetables, mushrooms, and seafood, while amid a spectacular show by maiko.

Events & Festivals

Owara Kaze-no-Bon (Toyama, Every September 1-3)

Kishiwada Danjiri Matsuri (Osaka, Mid-September)

It is a harvest festival on the streets of Kishiwada, and one of the popular viewpoints for the float parade is near Kispa La Park: the float handlers sing loud songs, and the rhythmic drums reverberate in the air.

Kitazawa Hachimanjinja Shrine Festival (Tokyo, Early September)

On the day of the festival, people carry mikoshi through the streets, with traditional dances and music adding to the festive atmosphere. You can try some local delicacies in food stalls, and the shrine is filled with various events. Don't miss the ceremony or performances on the open-air stage.

Still Dress Appropriately

Though September can still be warm in the first half, when visiting temples and shrines, it's necessary to dress appropriately and avoid exposure to show respect for local culture.

Bring a Raincoat

Make Backups

While the typhoon won't ruin your whole itinerary, it is still to noted that there might be one or two days' disruption when catching the direct impact, especially during your beach holiday. So, be empty some day for free exploration to make your itinerary flexible, prepare some indoor activities as an alternative, or just leave your planning to Odynovo to make all your backups to fully enjoy your journey.

Book Early

To ensure a smooth trip, it's recommended to book your journey, accommodation, and transportation in advance since the Silver Week is celebrated this year.
