Today I traveled from Urayasu to Shinjuku-Sanchome on the Tokyo Metro Marunouchi Line, but my IC card didn’t deduct any fare. The balance hasn’t changed, and transaction history shows 0 yen deducted. I tapped in/out normally with no gate errors. Has anyone had this issue? Should I visit a station office to fix it, or could it cause problems later? Thanks!
