If you’re planning to travel anywhere else via train during your stay, plan to start and end your trip at a Tokyo hotel. This way you can leave your large luggage at the hotel and do your train travel using small rollaway bags or packs. Train travel is much easier without large luggage as you don’t have the inconvenience of lugging your suitcases to and from stations or up and down onto platforms. The Shinkansen trains don’t have much dedicated space for large luggage either, so it is much easier with small bags that you can stow above your seat like in a plane. This way you can travel light, safe in the knowledge that your larger bags are being securely stored at your Tokyo hotel, free of charge, awaiting your return.
