The Japanese government has been ordered to pay one man a tax refund of almost $US2.5 billion.
Six years ago, Mr Takei was ordered to pay over $US1 billion in tax arrears and penalties on shares he received from his parents in 1999.
But the Supreme Court ruled that Toshiki Takei, the son of one of Japan's richest men, should not have been taxed on the share transfer because he was living in Hong Kong at the time.
Japanese newspapers say the payment, which includes interest, is the largest ever awarded to an individual taxpayer.
