    We are pleased to announce important changes regarding the UTokyo Daily Price Index from January 2016.  The number of stores from which prices are collected and the number of items covered will be substantially increased, and several new series, such as the frequency of temporary sales, will be added. Along with this, the name of the index will change to “Nikkei CPINow,”  and it will be jointly provided by Nikkei Inc. and Nowcast Inc. The latter is a new company started by Professor Tsutomu Watanabe of UTokyo with financial support from the University of Tokyo Edge Capital (UTEC) and Nikkei Inc. For details of the new index, please contact the UTokyo Daily Price Project (watlab at e.u-tokyo.ac.jp). The UTokyo Daily Price Project will also continue to support young researchers and students (graduate and undergraduate students) by providing the price data without charge. Please contact the address above if you would like to know more about this.
