Tokyo Stock Exchange Group Inc. said Monday it has approved the listing on April 1 of Dai-ichi Mutual Life Insurance Co., which will turn itself into a stock company.

It is still undecided whether the Tokyo-based insurance firm will be listed on the first section, the exchange said.

Dai-ichi Mutual decided to become a stock company at a meeting last June equivalent to a general shareholders' meeting.

By turning into a stock company, the insurance firm will be able to secure funds from the market and invest in future growth by focusing on overseas operations, including actively engaging in buyouts.
