Bank of Japan Case Study

Financial services companies in Japan have been reporting monthly data in XBRL to the Bank of Japan (BoJ) since February 2006.  The BOJ says the introduction of XBRL for monthly balance sheet information has led to a significant reduction in the burden of data validation and other gains in efficiency.  It plans to expand the scope of XBRL reporting and to develop new systems for storing and accessing its XBRL data.
