Climate
• September is still warm, especially in major cities like Tokyo and Osaka, where daytime temperatures are usually 25–30°C (77–86°F).
• Early mornings and evenings gradually cool down, and by late September temperatures may drop to around 20°C (68°F).
• Humidity remains high but is lower than in August, making it a little more comfortable.
Typhoons
• September is the peak of typhoon season in Japan.
Strong winds and heavy rain can affect travel plans.
• Trains (including the Shinkansen) and flights may be delayed or canceled during storms.
•Travelers should check weather forecasts frequently and keep their schedules flexible.
Clothing
• Light summer clothing (T-shirts, short sleeves) is fine during the day, but a light jacket, cardigan, or long-sleeve shirt is useful for cooler mornings and evenings.
• Comfortable walking shoes are recommended, and waterproof shoes or sandals are helpful for sudden rain.
• Always carry a folding umbrella or raincoat.
National Holidays
• There is a national holiday’Respect for the Aged Day (3rd Monday of September).
This is the day to honor the elderly. Sometimes it creates a long weekend called “Silver Week.”
• Autumn Equinox Day (September 23):
A holiday when day and night are nearly the same length.
Many families visit cemeteries to pay respects to ancestors.
Seasonal Events
• Otsukimi (Moon Viewing Festival):
Around mid-September, people enjoy viewing the full moon and eating rice dumplings (“tsukimi dango”).
Some temples and gardens hold special events.
•Autumn Festivals
Autumn is the harvest season of Japan.
There are many traditional harvest festivals and parades take place across Japan.
I recommend you check the local festival where you stay.
• Sports
There is a Grand Sumo tournament from 14-28 September at Ryogoku Stadium.
Baseball and J-League soccer are in season and very popular to watch.
Travel Tips

• Hot days still early September, so remember hydration, sunscreen, and a hat to avoid heat exhaustion.
• Mosquitoes are still common in September, especially outdoors, so insect repellent is useful.
• From late September, autumn leaves start to appear in northern areas like Hokkaido and in highland regions, offering beautiful scenery.
