4 major events happening this month

Owara Kaze no Bon
September 1–3
Toyama, Toyama
Toyama's haunting wind festival in the small hillside town of Yatsuo. Dancers in deep straw hats move silently through cobbled lantern-lit streets to mournful kokyu strings. Considered one of Japan's most beautiful festivals by locals — almost no foreign tourists.

Kishiwada Danjiri Matsuri
September 14-15 (main), plus early October
Kishiwada, Osaka, Osaka
One of Japan's most dangerous festivals — 4-ton wooden 'danjiri' floats are pulled through Kishiwada streets at full speed while acrobats stand on top. Serious accidents happen most years. Utterly thrilling to watch.

Sapporo Autumn Fest
Early to late September (about 3 weeks)
Sapporo, Hokkaido
Hokkaido's biggest food festival takes over Odori Park for three weeks. 200+ vendors serve Hokkaido specialties: uni, crab, jingisukan, corn, cheese, ramen, sake — all in one place.

Daisetsuzan National Park
September 20 – October 10
Kamikawa, Hokkaido
Japan's earliest autumn color — peak foliage arrives in late September. Japan's largest national park with stunning mountain panoramas in red, orange, and yellow.
