September 2025. As the intense heat of summer gradually subsides, a refreshing autumn breeze begins to blow, making it one of the most perfect times to travel through Japan. Having passed the peak tourist season, you can experience various unique local festivals and events in a relatively calm atmosphere across the country. In this article, we introduce must-see events happening in Japan this September, along with the unique charms of this time of year. We have compiled plenty of details—enough for about 5000 characters—so please use this guide as inspiration for your next trip!

Japan’s Climate and Charm in September

September sees vastly different climates depending on the region. In Hokkaido and the Tohoku area, the signs of autumn are already strong, and some places are beginning to see fall foliage. Daytime temperatures are comfortable, but mornings and evenings can feel slightly chilly. Meanwhile, regions from Kanto westward may still experience intense “late summer heat,” with days exceeding 30°C, but the mornings and evenings tend to become much more manageable.

The greatest appeal of this time is undoubtedly the palpable sense of (seasonal transition). It’s a unique atmosphere where the energy of summer coexists with the tranquility of autumn. While it is also typhoon season, requiring careful planning, if the weather cooperates, you can enjoy clear air and beautiful scenery.

Furthermore, September marks the beginning of the “harvesting autumn.” Delicious seasonal foods arrive in abundance, and harvest festivals and food-related events begin taking place across the country.

Here we introduce several major festivals and events that typically take place in September and are anticipated for 2025. (Note: The dates listed below are historical examples, so please check the official website of each event for the confirmed 2025 schedule.)

1. Kōnan Owara Wind Festival (Yatsuo Town, Toyama City, Toyama Prefecture)

(Typical Dates): September 1–3
(Overview): Known as one of Japan’s most atmospheric festivals, the “Kōnan Owara Wind Festival” is held in Yatsuo, a district in southern Toyama City. It was originally performed to pray for a good harvest and to appease the wind. In the townscape with many slopes, the melancholic sounds of *kokyū* (a type of bowed string instrument) and shamisen echo through the air as men and women wearing woven hats dance gracefully in silence.
(Appeal): Its greatest charm is its quiet, ethereal atmosphere, far removed from the hustle and bustle. The old townscape illuminated by paper lanterns, combined with the elegant figures of the dancers, deeply moves the viewer’s heart. Especially the circle dances (*waodori*) and street processions held late into the night transport you to a mysterious world. Because it is extremely popular, expect crowds. It is highly recommended to book accommodation and transportation well in advance. The townscape of Yatsuo, which seems designed for this festival, and the unique combination of songs and dances create a worldview that is worth experiencing at least once.

2. Kishiwada Danjiri Festival (Kishiwada City, Osaka Prefecture)

(Typical Dates): September Festival (Sat/Sun before Respect for the Aged Day), October Festival
(Overview): Known as a representative festival of “dynamic action,” the “Kishiwada Danjiri Festival” features massive *danjiri* (floats) weighing several tons racing through the streets at incredible speeds. The highlight is the *yarimawashi*, where they navigate corners without losing momentum—the sheer power and danger overwhelm the spectators.
(Appeal): It is breathtaking to see the star performers, called *daiku-gata*, dancing on the roof of the float while the energetic shouts of the pullers echo through the air. The entire town is enveloped in heat and passion, conveying the deep devotion of the local residents. Due to potential overcrowding and danger at viewing spots, extreme caution is necessary. This festival, which is a source of pride for Kishiwada citizens, is highly recommended for those who want to experience the dynamism of Japanese festivals. The September Festival takes place in the Kishiwada and Haruki districts, while the October Festival takes place in other areas.

3. Tsurugaoka Hachimangu Grand Festival & Yabusame Ceremony (Kamakura City, Kanagawa Prefecture)

(Typical Dates): Mid-September (Yabusame is typically on September 16th)
(Overview): This is the most important festival held at Tsurugaoka Hachimangu, a symbol of the ancient city of Kamakura. Various rituals take place during the period, but the most famous is the “Yabusame Ceremony.”
(Appeal): Yabusame—shooting arrows at targets from horseback while galloping—is a majestic ritual that evokes the era of the Kamakura samurai. The sight of archers, dressed in hunting attire, demonstrating superb horsemanship and archery skills is incredibly powerful. Held within an atmosphere of solemn tradition and history, it captivates many spectators. It would also be wonderful to visit other tourist spots in Kamakura. This is a dignified festival that captures the feeling of autumn arriving in an ancient city.

4. Seto Mono Festival (Seto City, Aichi Prefecture)

(Typical Dates): Second Saturday and Sunday of September

(Appeal): The greatest appeal is that you can see, touch, and purchase a diverse range of “Seto Mono,” from everyday tableware to fine art. There is the joy of finding a favorite piece while conversing directly with the creators. Many great finds are possible, making it an irresistible event for pottery lovers. In many years, fireworks are set off at night, offering a glamorous atmosphere different from the daytime bustle.

5. Tokyo Game Show (Makuhari Messe, Chiba Prefecture)

Seasonal Activities and Enjoyments Unique to September

Beyond large-scale events held on specific days, there are unique ways to enjoy Japan in September.

Moon Viewing (Tsukimi)

“Tsukimi,” the tradition of viewing the moon, is a quintessential Japanese autumn custom. While the full moon for the traditional 15th day of the eighth lunar month falls on October 6, 2025, beautiful nights with visible moons are common throughout September, and the culture of appreciating the moon remains deeply rooted. It is a graceful moment to arrange pampas grass (*susuki*), offer Moon Viewing rice dumplings (*moon mochi*) and taro root, and gaze upon the beautiful moon. In gardens or observation decks where the moon view is excellent, viewing events may be held. Enjoying the quiet length of the autumn night is also lovely.

Autumn Delicacies

September marks the beginning of the “autumn appetite,” bringing forth many delicious seasonal ingredients.

(Saba/Pacific Saury): A representative autumn delicacy. Grilled with salt is exceptional. (Although recent years have seen poor catches, it remains a highly anticipated seasonal flavor.)
(Mushrooms): Various mushrooms come into season, including Matsutake, Shimeji, and Maitake.
(Chestnuts): Dishes and sweets featuring chestnuts, such as chestnut rice or Mont Blanc, begin to appear.
(Pears and Grapes): Fresh fruits also reach peak season. It is a perfect time for fruit picking.
(New Rice): In earlier regions, new rice begins to be harvested, allowing you to rediscover the deliciousness of freshly cooked rice.

Many restaurants and traditional inns also feature special menus using these seasonal ingredients, so be sure to try them out!

Local Autumn Festivals (Akimatsuri)

Not only large events, but local shrines and temples across Japan also begin holding autumn festivals dedicated to giving thanks for a bountiful harvest. There are many simple, community-rooted festivals where you can experience the unique traditions and culture of that area. You might witness portable shrine processions (*mikoshi*) or traditional performing arts dedications, allowing you to feel the warmth of local people. Even small festivals encountered by chance while traveling can become wonderful memories.

Key Tips for Planning Your September 2025 Trip

(Weather Preparation): The climate varies greatly. It is advisable to pack layers of clothing, as the temperature difference between day and night can be significant. For peace of mind, bring items like hats, sunscreen, and water for heat protection, along with a light jacket or folding umbrella for sudden rain or drops in temperature. Be mindful of typhoon information.
(Accommodation & Transportation Booking): Accommodation near popular events (especially the Wind Festival or Danjiri Festival) can fill up extremely quickly. We strongly recommend planning early and booking your stay well in advance. Since public transportation is expected to be crowded, plan a schedule with plenty of buffer time.

(Diverse Options): It’s a season where you can enjoy more than just large events; you can visit special exhibitions at museums, picnic in parks, or relax in hot springs. Try to create an original itinerary based on your own interests.
