Are strollers allowed on Tokyo trains?

Yes, but they are incredibly difficult to maneuver during peak times. A lightweight umbrella stroller or a baby carrier is much more practical.

Where can I buy diapers and formula?

Every 'Drug Store' (look for Matsumoto Kiyoshi or Welcia) carries major diaper brands, and convenience stores (7-Eleven, Lawson) carry essentials, though local brands may differ from what you use at home.

Navigating Tokyo with Young Children

Prioritize rail passes, use baby carriers instead of strollers, and rely on convenience stores for quick snacks. Map out 'multipurpose toilets' in advance to ensure you have space for diaper changes and nursing.

Master the transport. Avoid rush hour (7:30 AM–9:30 AM and 5:00 PM–7:00 PM) at all costs. Use the 'Japan Transit' app to find routes with elevators, as some older stations only have stairs.
Use luggage forwarding. Don't haul suitcases and kids on the train. Use 'Takkyubin' (luggage forwarding) at the airport to send your bags to your hotel for about 2,000 yen per bag.
Locate child-friendly facilities. Look for the 'Baby Room' icon in department stores like Isetan or Mitsukoshi. These are oases with private nursing booths, hot water dispensers for formula, and clean changing tables.
Manage the sensory load. Tokyo is loud and crowded. Plan one high-stimulus activity in the morning (like a park or museum) followed by a quiet afternoon 'downtime' in your hotel or a public park.
