Japan Weather in September 2023, Travel Tips (for First-Timers)

Japan's autumn usually starts from September. The temperature decreases noticeably during the month.

September sees the second (heavier) rainy season (the typhoon season) hit central Japan, bringing highest rainfall months in central and northern Japan and typhoons, mostly in southern Japan.

Because of the wet weather, you'll benefit from the lowest costs and least crowds among the autumn months (September to November) in Japan.

Tokyo and Central Japan: Rainy but Quiet

Hot weather continues in central Japan in early September, but the temperature drops by 5°C (9°F) by the end of September. The daily highs average 28°C (82°F) in major cities, such as Tokyo, Osaka, Kyoto, and Hiroshima.

You may experience heavy rainfall in September. If you don't mind the risk of potentially rainy days, you're likely to have attractions to yourself, chances to climb Mt. Fuji before it closes in mid-September, and lower costs.

In September, Hokkaido is cool and pleasant, averaging 22°C (72°F). Hokkaido experiences its wettest month with rainfall of 135 mm (5 in). But it is still drier than other cities in Japan.

If possible, visit Hokkaido in the second half of September. Autumn leaves appear from late September. The cooler weather is more comfortable to have a soak in its hot springs.

You could head to Toyako (southwest Hokkaido) for romantic lake-view-hot-spring experiences. The daily firework displays nearby are not to be missed between April and October.

2. Tokyo: The Epitome of Japan

Tokyo is the standout city of Japan as well as a popular starting point for a family trip or couple's vacation.

September is the wettest month in Tokyo with short intense bursts of rain. But your Tokyo trip won't lose its charm even then, as Tokyo is famous for indoor activities. You could try a special sushi-cooking class, visit digital art museums, and experience animated culture in theme parks (like Ghibli Park) and themed cafes/shops (Pokemon Center).

Tokyo's seasonal events are bonuses as well. Don't miss the annual Grand Sumo Tournament from mid-September. If you like games, the Tokyo Game Show, which is packed with the latest games and high-tech, could be your holiday highlight.

Osaka is still affected by summer heat in September, with daily temperatures averaging 22–29°C (72–84°F).

If you're a theme park fan, you could enjoy a less-crowded Universal Studios and Super Nintendo World in September. You'll have chances to experience Halloween events inside the Studios from early September.

Looking for an exotic experience in September? Look no further than the Kishiwada Danjiri Matsuri. You'd watch thrilling team competitions involving maneuvering large wooden portable shrines called danjiri through winding streets.

4. Mt. Fuji: A Breath-Taking Marvel

Considering the weather, climbing Mt. Fuji is only available from July to September. Seize the last chance of the year to climb the iconic Japan mountain.

The mild weather makes it easier to climb without the challenges of the summer heat. Away from summer crowds, it's the perfect time to avoid the long queues.

For a more relaxing way to experience Mt. Fuji, you could see it from a sightseeing cruise, a cable car, or even a serene ryokan (a traditional inn with a hot spring bath).

5. Nagoya: Futuristic Robotics and Formula 1

Being a popular stop between Tokyo and Kyoto, Nagoya is mild and humid in September.

Nagoya is home to samurai and ninja culture, but Nagoya Castle tops the must-see list for a Nagoya trip.

It is also a hub for futuristic inventions and robotics, so your trip would not be complete without SCMAGLEV and Railway Park as well as Toyota Commemorative Museum of Industry and Technology.

If you seek stimulating moments, check out the Formula 1 Japanese Grand Prix (September 22–24, 2023). See and hear the ultimate super cars travelling at speeds exceeding 300 kph (180 mph)!

Will a Typhoon Affect My Trip in September?

Typhoons usually hit southern Japan more heavily than central and northern Japan. If you mainly visit the central cities (Tokyo, Kyoto, and Osaka) or Hokkaido, your trip should be less affected.

A typhoon usually lasts one or two days, unless exceptionally strong and damaging. But you're likely to have clear skies and crisp air before/after it.

During a typhoon, flights or trains might be delayed. So, leaving some flexibility is advisable for potential itinerary changes.

What to Pack in September

The weather turns from hot to warm/mild in September, so you could take your summer clothes for daytime activities if you're moving around, but carry something warmer to wear (e.g. a fleece jacket or hoodie) for evenings or if you find yourself getting cool. Warm layers are suggested if you plan to visit cooler North Japan.

As the second rainy season peaks in September in Japan, you're suggested to take rain gear and sandals.
