Mido-suji Boulevard's tree lighting begins mid-October, illuminating the central Osaka boulevard with white and gold lights. This continues through January. USJ launches Halloween events including Halloween Horror Nights — adults-only horror mazes that draw international visitors.
Hotel prices climb back to spring levels but remain below sakura season peaks. Book 2-3 months ahead. Restaurants reopen al fresco seating at Yodogawa beer gardens until early November.
Genuinely the best month for first-time Osaka visitors who can't time cherry blossoms.
