Odaiba (DiverCity, Fuji TV, Palette Town)

Odaiba is Tokyo's futuristic waterfront entertainment island, connected by a rainbow suspension bridge and monorail with stunning Tokyo Bay views. Adjacent Fuji TV Building's rooftop sphere offers panoramic views for 700 JPY, while the artificial beach, teamLab venues, and Legoland Discovery Center (2,800 JPY) provide a full-day experience. Over 5,000 TripAdvisor reviewers note Odaiba is one of Tokyo's few genuinely stroller-friendly districts, with flat, wide promenades and extensive covered shopping in Aqua City and Venus Fort. This combination of free and paid activities makes it a balanced choice for Hong Kong families.
