Japan logged a record low first-half current account surplus of ¥2.024 trillion in the April-September period, as the soaring trade deficit outweighed expansion of income from foreign investment, government data showed Tuesday.

The surplus in the primary income account, which reflects how much Japan earns from its foreign investments, gained 1.4 percent from the previous year to ¥9.149 trillion, the largest for the half fiscal year, the Finance Ministry said in a preliminary report.

But the balance of goods traded marked a deficit of ¥4.397 trillion, reducing the country's current account surplus — one of the widest gauges of international trade for a nation.
