Japan's largest rail operator says problems with its online reservation system have resumed seven hours after the trouble was first reported on Tuesday morning.
Officials at East Japan Railway Company say it could not have something to do with the new rate.
The officials say the trouble started at around 5:30 a.m. Tuesday morning on the system of receiving tickets ...reserved on the "Eki Net" website ... from machines at train stations. This affected many of their services in and around Tokyo.
Workers had put up notices asking customers to get their tickets at counters. No confusion has been reported.
Over 10 million people are registered with "Eki Net." They can use the site to reserve tickets for the Shinkansen and express trains and then receive their tickets at stations.
