Preface

In the Short-term Economic Survey of Enterprises in Japan (Tankan) of March 1999, the Bank of Japan changed the sample for the All Enterprises Tankan, which consists of approximately 10,000 enterprises nationwide, for the first time in five years, and also changed the aggregation methodology. Additionally, the Tankan release format was changed from the prior focus on the results of the Principal Enterprises Tankan to one centered around the results of the All Enterprises Tankan so that users can make consistent comparisons by scale and grasp economic conditions as accurately as possible. 1

The Bank of Japan views statistics as public goods, and endeavors to disclose information related to the statistics it prepares itself as widely as possible. Accordingly, this paper presents a somewhat detailed explanation regarding the All Enterprises Tankan, which is the center of the revision, covering the sample design and aggregation methodology, as well as information regarding the sample maintenance and management practices.
