Tokyo Stock Exchange to introduce XBRL reporting system

26 April 2006

The Tokyo Stock Exchange (TSE) has announced it is introducing an XBRL reporting system, saying consumers of financial information will find XBRL an extremely effective technology for receiving and analysing corporate financial information.

XBRL would also ensure the timely provision of information, enhancing the setting of market prices on basis of rational investment judgements, the TSE said in a statement. 

“The Tokyo Stock Exchange will work hard to spread XBRL and ensure this effective technology is used by securities markets,” its statement added. 

XBRL is already being incorporated into EDINET, the statutory disclosure system used by Japan’s Financial Services Agency.  The TSE said its moves to adopt XBRL for receiving and disseminating information on business results were in line with the Japanese FSA’s actions. 

The TSE has launched a trial service showing Japanese earnings In order to deepen knowledge on XBRL among Japanese investors and listed companies.  This gives an overview of XBRL Japan and the Tokyo Stock Exchange's efforts to develop e-disclosure.  It shows examples of XBRL data as well as the draft taxonomy for earnings digests stored at Tdnet (Timely Disclosure Network).
