"IPA Font" series(Ver.003 and upper), "IPAex Font" series (Ver.001 and upper) and "IPAmjMincho Font" (Ver.001 and upper) is able to use with the agreement to "IPA Font License", which is consistent with international business practice and endorsed by Open Source Initiative (OSI) as confirmed license with Open Source Definition (OSD). The recipient may create, use, reproduce and/or redistribute a derived font program under the terms for the licensed font program provided, that the recipient shall follow "IPA Font License" when redistributing the derived font program. In this paper, we investigate the situation that how the derived font program that modified Japanese open font is distributed with. As a result, we revealed that "IPA Font License" did some contribution for software industrial development. In addition, it was suggested that some derivation fonts might violate the license.
