This mistake is likely to cost the community of Abu in Yamaguchi Prefecture, Japan dearly.
In early April, the city government prepared a Covid relief payment to 463 low-income households of 100,000 yen each.
But the money never reached 462 recipients.
By mistake, the entire amount of 46.3 million yen was remitted to just one single man;
his name had been first on the list of recipients.
The twenty-four-year-old didn't hesitate and, according to his own account, gambled away the unexpected windfall within a few days in international online casinos - it had to be international casinos because Japan doesn't allow such gambling.
It took some time for the city to notice the mistake.
Last week she sued the man for 51 million yen back;
this corresponds to the amount of damage plus the expenses for the lawyer.
The money was gone and he was blank, the man initially said, according to his lawyer.
On Wednesday he was remorseful and said he wanted to pay back the money, piece by piece, in small amounts.
