The Japan Railway group says its credit card payment system is now back online nationwide. A glitch early on Monday left travelers unable to use the form of payment, creating headaches for the morning commute.
JR officials say the problem started at around 4 a.m. and lasted five hours. They say there was a technical issue in the server that processes credit payments.
The last train schedules in and around the Japanese capital will be extended by up to two hours during the Tokyo 2020 Olympic Games.
Some events at the 2020 Games will end after 11 p.m. As a measure to allow spectators to get home easily from venues, the Tokyo Metropolitan government, the Olympic organizing committee and 19 railway operators agreed to extend the train service hours.
