The Tokyo Stock Exchange is failing in its duty as a market referee, according to the chairman of a prominent Japanese investment fund.

The TSE must serve as arbiter of the regulations for companies that it started in June 2015, said Yasushi Ando of New Horizon Capital Co., who¡¯s also an adviser to the Tokyo Metropolitan Government.

If it doesn¡¯t, executives will assume they can ignore the rules, which aren¡¯t legally binding, he said.
