National Consumer Price Index (CPI) is the key gauge for inflation in Japan. Simply put, inflation reflects a decline in the purchasing power of the Yen, where each Yen buys fewer goods and services. In terms of measuring inflation, CPI is the most obvious way to quantify changes in purchasing power. The report tracks changes in the price of a basket of goods and services that a typical Japanese household might purchase. An increase in the index indicates that it takes more Yen to purchase this same set of basic consumer items.

Markets will typically pay more attention to "CPI excluding Fresh Food," because it excludes volatile food prices that can distort overall CPI. The headline figure for CPI is the percentage change in the index on a month to month or year to year basis.

As the most important indicator of inflation, CPI figures are closely followed by the Bank of Japan. Rising Consumer Prices may prompt the BoJ to raise interest rates in order to manage inflation and slow economic growth. Higher interest rates make holding the Yen more attractive to foreign investors, and this higher level of demand will place upward pressure on the value of the Yen.

The percentage of individuals in the labor force who are without a job but actively seeking one. A higher Unemployment Rate is generally a drain on the economy. Not only does it mean that resources are not being fully utilized, but it also results in lower consumer spending as there are fewer workers receiving paychecks.

Note: The unemployment rate generally moves slowly, so changes of only a few tenths of a percent are still considered significant. Also note that the unemployment rate does not account for discouraged workers. Therefore, in an economically depressed environment, such as that which occurred in Cold War era East Germany, the Unemployment Rate may not accurately reflect the extent of problems.

Measures the per volume change in output from mining, quarrying, manufacturing, energy and construction sectors in Japan. Industrial production is significant as a short-term indicator of the strength of Japanese industrial activity. High or rising Industrial Production figures suggest increased production and economic expansion. However, uncontrolled levels of production and consumption can spark inflation.

The report is only a preliminary estimate figure that does not move the markets much. The figure is released in headlines as a monthly percent change.

Gauge for goods sold at retail outlets in the past month. Retail Sales is a leading indicator for the economy. Rising consumer spending fuels economic growth, confirms signals from consumer confidence, and may spark inflationary pressures.

The headline figure is expressed as the percentage change from the same month last year.
