Millea Holdings Inc. Chairman Tomio Higuchi will resign from the post at the end of this month as well as from his concurrent chairmanship of Tokio Marine & Nichido Fire Insurance Co., and become adviser to the insurer on April 1, the company said Monday.

Higuchi decided to exit the insurance company, created through the Oct. 1 merger of Tokio Marine & Fire Insurance Co. and Nichido Fire & Marine Insurance Co., after it was judged to have moved into gear after about six months into its operation, officials of the holding company said.

Higuchi was president of Nichido Fire & Marine Insurance until its merger with Tokio Marine & Fire Insurance.
