Want to know the fluctuation of commodity prices and the item-specific prices in some region?
Here tells you the trend of supermarkets’ commodity prices of the whole country.
Nikkei CPINow is a price indicator called Törnqvist index which has the most desirable property in the theory of index. In order to cut down on expenses, statistical department of each country do sample survey of the objective products. By contrast, Nikkei CPINow uses POS system to collect information online so it’s possible to investigate all the products sold in supermarkets instead of sampling (full investigation). It’s the main difference between Nikkei CPINow and the existing indices and it has effect on improving the accuracy so it becomes possible to analyze the true cause of deflation.

Nikkei CPINow was quoted in Mr. Kuroda’s lecture right after the introduction of Negative Interest Rate Policy, gist of policy decision conference, press conference and so on. It's actually used by policy authorities for policy considerations.
