- New price index utilizing T-Point data: "T-POINT Price Index (TPI)" -

CCC Marketing Inc. (hereinafter "CCC Marketing"), a database marketing company, and Culture Convenience Club Co., Ltd. (hereinafter "CCC") have begun daily data updates for the "T-POINT Price Index (TPI)" (hereinafter "TPI"), a new price index that utilizes T-Point data, which is a joint project with the Watanabe Tsutomu Laboratory at the Graduate School of Economics, The University of Tokyo. In addition, in addition to the existing "supermarkets" and "drugstores," we have added "convenience stores" and "restaurant chains" to the target data used by TPI. As a result, coverage when CPI is 100% increased by 7 points to 23.4%.
In creating the TPI, we requested research cooperation from the National Statistics Center of Japan, an Independent Administrative Institution, and by aligning the product classifications of T-Point partner companies with the item classifications in the Ministry of Internal Affairs and Communications' Family Income and Expenditure Survey, we were able to scrutinize the data of each partner company on an item-by-item basis. In the future, we will also consider creating indices on a product-by-product basis.

Daily Index

*You can view data by selecting from three business types: "supermarket," "drugstore," and "convenience store."
*Daily index data is up to three days prior.

What is TPI?

The Consumer Price Index (CPI) is known as an economic thermometer that indicates economic trends. On the other hand, the TPI is an index compiled based on purchase price data accumulated daily through T-Point partner stores across Japan. Specifically, this price index was derived by aggregating, tabulating, and analyzing purchase amounts obtained from T-Card purchasing data, which is used by 55.19 million people across Japan (number of members after name matching as of the end of August 2015) and has related sales of over 5 trillion yen, which accounts for approximately 2% of Japan's total consumption.

About TPI

The data currently used by TPI collects the amount of purchases involving T-Cards at T-Point partner stores such as supermarkets, drugstores, convenience stores, and restaurant chains. Store areas are as follows: supermarkets are mainly in the Tokyo metropolitan area and Kyushu, drugstores are mainly in Kanto, Kansai and Kyushu, and convenience stores and restaurant chains are nationwide. Currently, the number of products (SKUs) covered by TPI is approximately 110,000, with 191 of the 580 items being utilized, resulting in a coverage of 23.4% when the Ministry of Internal Affairs and Communications CPI is taken as 100%. The amount used to calculate TPI is excluding consumption tax (excluding tax). Additionally, while no special consideration is given to sale items, all products with sales history for both the previous and current periods are used to compile TPI. Please note that the number of members covered by TPI, as well as the transaction amount and number of uses, have not been disclosed.

TPI Features

The features of TPI are that it allows you to see the price index by gender and age group, and that it is a price index based on buying prices rather than selling prices. The TPI is calculated using the Tornqvist method, which is the same as the University of Tokyo Daily Price Index. This calculation method places more weight on products purchased in larger quantities, and there is a consensus among researchers that it is the best method for creating a price index.
