May in Japan — events that affect travel

Known cultural, religious, or national events that surge prices, fill hotels, or close businesses during this month. Plan around them, or build your itinerary around the ones you'd like to see.

Golden Week
Travel surge · high impact

Japan's biggest domestic travel week — Showa Day through Children's Day. Trains, hotels, and attractions across Japan run at peak capacity; prices spike 30-100%, reservations vanish weeks ahead.

Plan: If you're visiting Japan in late April/early May, book trains and ryokan 2-3 months out. Or avoid the window entirely.
