Greece made a €148m (£104m, $162.87m) repayment on its 20-year old Samurai bond which matured on 14 July to private creditors in Japan.
"The payment was made, the funds should be credited in the bondholders' accounts," a Greek government official told Reuters. Japan's Mizuho Financial Bank spokeswoman confirmed that the payment was made, AFP said.

Greece sold Samurai bonds to investors in 1995 worth ¥11.7bn (£60.25mn, $94.77m)and another ¥46.4bn in 1996. There were concerns that Greece would also miss payment on the Samurai bonds.
Nizam Idris, head of strategy, fixed income and currencies at Macquarie Bank said that Greece likely prioritised the Samurai bond payment because if it missed this payment it would be the first default on a private sector debt, he told CNBC.

He noted that although the payment was not a huge amount, it does indicate that Greece did have some liquidity.
Idris noted that the cost of the 5 July referendum in Greece cost more than the payment on the Samurai bonds. AFP had estimated the poll to cost about €110m (£77.32m, .
