The Index includes account inventory ratios, machinery orders, stock prices and other leading economic indicators. As the aggregate of many leading indices the Leading Economic Index provides a forecast of the future state of the domestic economy and is thought to predict activity that will occur 6-9 months after the reporting period.

The index operates on a 1-100 scale, where a value lower than 50 means that most indictors are negative and a value higher than 50 means most indicators are positive. In both cases a greater distance from the midpoint (50) means that the indicators are more strongly positive or negative.

A surplus reflects capital flowing into Japan in exchange for Japanese exports, and a deficit means that capital is flowing out of Japan as imports are purchased in larger volumes by Japanese consumers. A trade surplus will act as an appreciating weight on the Yen, whereas a trade deficit will place downward pressure on the Yen's value.

Details in the Trade Balance report itself give useful insight into changing trends regarding Japanese trade. Such developments are especially important for the country, which is an export-oriented economy that has historically experienced large trade surpluses. Any affect on this could have dramatic affect on the domestic economy.

The headline figure for trade balance is expressed in millions of Yen and usually accompanied by a year-on-year percentage change figure.
