Frequently Asked Questions

Is September a good time to visit Japan?+
Late September (after the 20th) is excellent — summer heat fades, typhoon risk decreases, autumn colors begin in Hokkaido, and tourists are far fewer than peak seasons. Prices are moderate and accommodation is easier to find.
What is Silver Week in Japan?+
Silver Week occurs when Respect for the Aged Day (3rd Monday of September) and Autumnal Equinox Day (around Sept 22–23) fall close enough to create a multi-day holiday cluster. It's a significant domestic travel period when this occurs.
Is there typhoon risk in September?+
Yes — September is prime typhoon season, particularly the first three weeks. Check weather forecasts before travel. Typhoons can cause transport cancellations. Travel insurance covering weather disruption is recommended.
When does autumn foliage start in Japan?+
Autumn foliage (koyo) starts earliest in Hokkaido — Daisetsuzan peaks in late September. It gradually moves south, reaching central Honshu in October and Kyoto/Tokyo in mid-to-late November.
What is Tsukimi in Japan?+
Tsukimi (Moon Viewing) is a traditional harvest moon celebration, held on the 15th day of the 8th lunar month (usually September or October). People display tsukimi dango (white rice dumplings), pampas grass, and seasonal vegetables while viewing the full moon.
