Frequently Asked Questions

What is Obon in Japan?+

Obon is a Buddhist custom to honor the spirits of ancestors who return to visit families for three days (August 13–16 in most regions). Families light fires to guide spirits home, visit graves, and participate in bon odori (circle dances). It's one of Japan's most important traditional events.

How hot is Japan in August?+

August is Japan's hottest month. Tokyo and Osaka regularly reach 33–35°C with high humidity. Plan indoor activities during 11am–3pm, use air-conditioned transport, and stay hydrated. Hokkaido is a cooler alternative at 25–28°C.

Can I climb Mt. Fuji in August?+

Yes — August is peak Fuji climbing season. The Yoshida Trail (most popular) is open July 1–September 10. Expect crowds on weekends. Start your climb at night to avoid crowds and catch the sunrise (goraikō) from the summit.

What is the Awa Odori festival?+

Awa Odori in Tokushima is Japan's largest dance festival held August 12–15. Over 100,000 dancers in colorful yukata perform the traditional "fool's dance" through the streets while 1.3 million spectators cheer. The atmosphere is electric and infectious.

Is Okinawa worth visiting in August?+

Okinawa in August is hot (30–33°C) but the water is crystal clear and perfect for snorkeling and diving. The typhoon risk increases in August, so check forecasts before booking. Smaller islands like Miyakojima and Ishigaki are spectacular.
