JR East & Tokyo Metro (carrier rule)
All wards ยท Citywide rail and subway network
Both JR East and Tokyo Metro allow dogs only when fully enclosed in a carrier that stays closed for the whole ride, with the animal and carrier together kept within the operator`s combined size and weight limits (broadly a compact carrier and a total under roughly 10 kg). JR charges a small hand-luggage fee bought at the ticket gate; verify the exact current limits with staff before you travel.
๐ก Avoid rush hour: Tokyo trains are extremely crowded and a carrier is hard to protect at peak times.
