A train diver is suing his employer after was 36p was taken out of his wages following a minor delay.
The Japanese train driver was fined after a work mix-up caused a one-minute delay to operations.
JR West, the train company, argued no labour had been performed during the stoppage.
Japan's rail system is well known for its punctuality.
The disgruntled employee is seeking £14,347 (2.2million yen) in damages for mental anguish caused by the ordeal.
The unnamed employee was scheduled to pilot an empty train to Okayama station in the south of the country but he arrived at the wrong platform while waiting to take over from the previous driver, Japanese news site Soranews24.
By the time the driver realised the mistake and went to the correct platform, the transfer between the two drivers had been delayed by two minutes.
This resulted in a one-minute delay in the train's departure and a further one-minute delay in warehousing the train at the depot.
JR West initially docked the driver by 55p (85 yen) but later agreed to reduce the fine to 56 yen after the employee took the case to the Okayama Labour Standards Inspection Office.
However, the driver has refused to accept the reduction.
He argued the delay did not cause any actual disruption to the timetables or passengers because the train was empty at the time.
The company fired back saying it applied the "no work, no pay principle", meaning they would treat it in a similar way to if an employee was late or had an unexplained absence.

The country's rail system is famous for being on time. In 2017, a rail line issued an apology after one of its trains left a station 20 seconds early.
If a train is delayed by more than five minutes, passengers are issued with a certificate they can use as an excuse for being late.
