Citigroup has been having problems in Japan lately, the newest one involving its new computer system. Earlier this month, Associated Press reports, the bank’s branches in Japan had difficulties with nearly 275,000 bank transactions, involving yen savings accounts, U.S. dollar savings accounts, checking accounts, international loan cards and money advances, according to AP.

Over the past year, Citigroup’s Japan operations had a series of run-ins with regulators. In one incident, Japan’s Financial Services Agency ordered the bank to stop all new operations after alleging that its trust banking unit misled inspectors and violated accounting rules. In another, the FSA took away Citi Japan’s private banking license taken away after the FSA accused it with not implementing safeguard to prevent money laundering and for misleading customers about financial risks. Citibank reportedly is the largest U.S.-based bank in Japan with 1,200 employees.
