This study aims at comparing the change of accounting systems of Korea and Japan in dealing with global accounting standards, the degree of conformity of each country`s accounting standards to the international accounting standards and the strategies for global accounting standards. And it is expected that this study will provide suggestions that would help both Korea and Japan promote the preparation of global accounting standards. While the KASB(Korea Accounting Standards Board) functions as an independent organization of accounting standards, the ASBJ (Accounting Standards Board of Japan) takes on the role of establishing accounting standards but coexists with Business Accounting Deliberation Council, a government organization. The newly established accounting standards by KASB and ASBJ are assessed to accord with IAS/IFRS on the whole.
