Tokyo Dome City · near Suidobashi Station (JR / Toei Mita Line) or Korakuen Station (Marunouchi / Namboku Line), 1–3 min walk
Large BorneLund-designed indoor play park inside Tokyo Dome City, with five themed zones: a 40,000-ball pool, a Plarail/train area, pretend-play town, an active-play 'Sky Kids' climbing area, and a dedicated baby garden for under-2s.
Why children love it: Huge ball pool, endless Plarail trains, dress-up shop-play, and soft climbing structures — all indoors and age-zoned so little ones have safe space.
Honest drawbacks: Best for babies through early-elementary; older kids may outgrow it fast; weekends and holidays get crowded and pricier; signage mostly Japanese.
