Bank of Japan


The Bank uses a sample survey framework for the Tankan (Short-term Economic Survey of Enterprises in Japan).  It randomly extracts samples from a population (excluding financial institutions) with capital of at least 20 million yen, based on the "Establishment and Enterprise Census of Japan " conducted by the Ministry of Internal Affairs and Communications. 

To grasp actual economic conditions accurately, the Bank makes regular revisions to the Tankan sample enterprises when the Ministry updates the "Establishment and Enterprise Census of Japan ."  Today, the Bank made revisions to the sample enterprises that are based on the most updated population (210,000 enterprises based on the"2006 Establishment and Enterprise Census of Japan ").
