Tokyo Metro’s current 1-Day Open Ticket will be replaced by an even more convenient 24 Hour Ticket from Saturday March 26th.
Tokyo Metro’s current “1-Day Open Ticket” offers unlimited travel on all Tokyo Metro lines for just 600 yen for adults and 300 yen for children. This ticket’s period of validity is fixed by the first and last trains of the day it is purchased. So no matter what time you buy the ticket, whether it is 9:00 in the morning, or 5:00 in the afternoon, the ticket can only be used up until the last train of that day.
