September in Japan: Understanding the Weather

September marks the beginning of autumn in Japan, bringing cooler temperatures and the start of the fall foliage season in northern regions. However, the month can also see the tail end of typhoon season, so it’s important to be prepared for varying weather conditions.

Regional Weather Differences

• Hokkaido: The northernmost island of Hokkaido begins to cool down significantly in September, with temperatures ranging from 12 to 23 degrees Celsius. This is the start of the autumn foliage season, making it an ideal time for outdoor activities like hiking and nature walks.

• Kanto: The Kanto region, including Tokyo, sees milder weather compared to August, with temperatures ranging from 20 to 28 degrees Celsius. While the chance of rain remains due to the tail end of typhoon season, the cooler days make exploring the city more comfortable.

• Kansai: In the Kansai region, including cities like Kyoto and Osaka, temperatures range from 22 to 30 degrees Celsius. Early autumn brings a mix of warm days and cooler evenings, ideal for sightseeing and outdoor events.
• Chubu: The Chubu region’s Japanese Alps begin to see cooler temperatures, making it perfect for trekking and enjoying the early signs of autumn. Coastal areas like Nagoya remain warmer, with temperatures between 21 and 29 degrees Celsius.

• Okinawa: Okinawa remains warm in September, with temperatures ranging from 25 to 30 degrees Celsius. While it’s still beach weather, the island is also at the tail end of typhoon season, so it’s important to keep an eye on weather forecasts.

September in Japan: Tips for Packing Appropriately

Packing for Japan in September requires a mix of clothing to accommodate the transition from summer to autumn, as well as potential rain showers.

• Layered Clothing: As temperatures begin to cool, especially in the evening, it’s a good idea to pack layers. Lightweight sweaters, long sleeves, and light jackets will help you stay comfortable throughout the day.
• Rain Gear: September can still bring rain, particularly in the form of typhoons. A compact umbrella and a waterproof jacket are essential items to keep you dry.
• Comfortable Footwear: With cooler weather, September is a great time for walking tours and exploring Japan’s outdoor sites (which is exactly what we do in our Unknown Japan Tour, scheduled in mid-September). Make sure to pack comfortable shoes suitable for long days of sightseeing.

Japanese Festivals and Events in September

While September may not have as many festivals as August, it still offers a variety of cultural events that provide insight into Japan’s traditions and seasonal changes.

• Kishiwada Danjiri Matsuri (Osaka): Held in mid-September, this is one of Japan’s most thrilling festivals. Large, ornate wooden floats (danjiri) are pulled through the streets at high speeds by teams of men. The event is both exciting and a display of community spirit.

• Tsukimi Festivals: Across Japan, various Tsukimi events take place, especially in historical towns like Nara and Kyoto. These festivals often feature traditional music, tea ceremonies, and the offering of seasonal foods to the moon.

Tsukimi: Japan’s Autumn Moon Viewing Tradition

September in Japan is highlighted by Tsukimi, a traditional festival dedicated to admiring the full moon. This event is rooted in the country’s agricultural past and offers a serene contrast to the lively summer festivals.

What is Tsukimi?

Tsukimi, or “moon viewing,” is a celebration of the autumn harvest and the beauty of the full moon, which is considered the brightest and most beautiful of the year in September. The festival has been celebrated since the Heian period (794-1185) and is a time to appreciate nature’s beauty, give thanks for the harvest, and enjoy seasonal foods like dango (sweet rice dumplings) and chestnuts.

The festival typically takes place on the 15th day of the eighth month of the traditional Japanese lunar calendar, which usually falls in mid to late September. Families and friends gather to enjoy moon viewing parties, often held in gardens, on balconies, or at special events in parks and temples.

Key Traditions and Rituals

• Tsukimi Dango: These small, round rice dumplings are offered to the moon as a symbol of gratitude and are often displayed on a small altar decorated with seasonal grasses like susuki (Japanese pampas grass). After the offering, the dango are shared among those present.
• Seasonal Decorations: In addition to susuki, seasonal fruits and vegetables like persimmons, chestnuts, and taro are also placed on the altar as offerings. These items symbolise a bountiful harvest and are part of the traditional Tsukimi celebration.
• Moon Viewing Parties: People often gather in scenic locations to enjoy the full moon, sometimes with traditional music performances, tea ceremonies, and poetry recitations dedicated to the beauty of the moon.

Experiencing Tsukimi as a Tourist

For visitors to Japan, Tsukimi provides a peaceful and culturally rich experience. While it may not be as boisterous as summer festivals, it offers a deep connection to Japan’s natural beauty and traditional customs. Here’s how you can experience Tsukimi during your September visit:

• Visit a Temple or Garden: Many temples and traditional gardens host Tsukimi events, where you can participate in moon viewing, enjoy performances, and learn about the history and significance of the festival.
• Attend a Tea Ceremony: Some venues offer special Tsukimi-themed tea ceremonies. These are a great way to immerse yourself in Japanese culture while enjoying the serene atmosphere of the event.
• Explore Local Markets: During September, many markets sell seasonal Tsukimi treats, like dango and chestnuts, which you can enjoy as you take in the autumn scenery.

Exploring Nature in Japan in September

September is an ideal time to explore Japan’s natural beauty as the country begins to cool down and the autumn foliage starts to appear in northern regions.

• Nikko National Park: Located in the Kanto region, Nikko is known for its beautiful autumn colours, which start to appear in late September. The park is also home to historical sites like Toshogu Shrine, making it a perfect blend of nature and culture.
• Daisetsuzan National Park: Hokkaido’s Daisetsuzan National Park offers some of the earliest autumn foliage in Japan. The park’s rugged terrain and cooler temperatures make it ideal for hiking and enjoying the crisp autumn air.
• Kamikochi: This mountain valley in the Japanese Alps remains a popular destination for outdoor enthusiasts. September offers cooler temperatures and stunning views of the surrounding mountains, making it perfect for trekking.
• Beaches: While September marks the end of peak beach season, southern regions like Okinawa still offer warm weather for swimming and water sports. The reduced crowds make it a more relaxed experience compared to the summer months.

September in Japan: Seasonal Foods

As Japan transitions into autumn, the cuisine also changes to reflect the new season. September is a time for hearty, warming dishes that showcase the bounty of the harvest.

• Matsutake Mushrooms: These prized mushrooms are a delicacy in Japan and are in season from September. Often served grilled or in a simple broth, matsutake are a must-try for food lovers visiting Japan in the fall.
• Sanma (Pacific Saury): September marks the beginning of the sanma season. This oily fish is typically grilled and served with a side of grated daikon (radish), making for a delicious and healthy meal.
• Kuri (Chestnuts): Chestnuts are a popular autumn treat in Japan. You’ll find them in a variety of dishes, from roasted chestnuts sold by street vendors to kuri-gohan (chestnut rice) served in traditional restaurants.
• Soba: As the weather cools, hot soba (buckwheat noodles) becomes a popular dish. Many regions have their own variations, often served with seasonal toppings that highlight the flavours of autumn.

September in Japan: Staying Healthy

The milder weather of September is generally easier to manage than the heat of August, but there are still some health considerations to keep in mind.

• Stay Hydrated: While the temperatures are cooler, it’s still important to stay hydrated, especially if you’re engaging in outdoor activities. Japan’s vending machines and convenience stores continue to offer a wide variety of drinks.
• Be Prepared for Allergies: Autumn can bring seasonal allergies, particularly from pollen. If you’re prone to allergies, consider bringing antihistamines or other remedies.
• Sun Protection: The sun can still be strong in September, so continue to use sunscreen and wear a hat and sunglasses when spending time outdoors.
