Ticket machines were out of service at some stations Friday on bullet train lines across Japan due to a technical glitch.
The machines went offline in the morning at stations including Shin-Yokohama and Nagoya. Railway Information Systems Co. said the problems occurred following a system upgrade.
The company, founded by shinkansen operators, said machines froze each time passengers tried to buy round-trip tickets for unreserved seats. The cause is still under investigation and some machines remained out of order as of Friday afternoon.
A woman in her 50s who was on her way back to Nagoya from Shin-Yokohama said, "I had to wait in line for 30 minutes at a ticket counter. It was very inconvenient."
