The latest reading marks the 74th successive month the current account has been in surplus, the report showed.
The ministry also said in its preliminary report that the country had a goods trade surplus of 413.2 billion yen (124.45 million U.S. dollars), while services trade stood at a deficit of 316.6 billion yen (2.98 billion U.S. dollars) in the reporting period.
Japan's primary income, which reflects returns on overseas made investments, logged a surplus of 2.25 trillion yen (21.21 billion U.S. dollars), the ministry also said.
Japan's current account surplus is one of the broadest measure of its trade with the rest of the world.
The data is keenly eyed by the Bank of Japan (BOJ) and the finance ministry ahead of new potential policy changes or monetary easing or tapering measures.
In Japan, the current account surplus increases the nation's net foreign assets by the corresponding amount, and a current account deficit does the reverse.
Both the Japanese government and private payments are included in the calculation and it is called the current account because goods and services are generally consumed in the current period.
