Developer Mitsubishi Estate Co., industrial waste recycler Daiseki Co. and Mizuho Trust & Banking Co. were honored Wednesday as the most "sincere" companies in Japan.

The selections were made by KPMG Financial, Inc. (KFi) and Integrex Inc.

KFi, a Tokyo-based consulting firm, and Integrex, an investment advisory/research firm, jointly came up with the idea of creating an "integrity award" to pep up companies with ethical and honest management, officials said.
