Current Responsibility

Since joining Milliman’s Tokyo office in January 2002, Toshio Tanaka has worked on both life and non-life insurance. He provides consultations in areas such as actuarial product development, embedded value development, and appraisal.


Before joining Milliman, Tanaka spent six years working with Mitsui Marine & Fire Insurance (which later became Mitsui Sumitomo Insurance Company Ltd.). Focusing on accident insurance, he was engaged in profit management, product development, and relevant system development in the actuarial section and injury and disease insurance section of the non-marine underwriting department. While working for Mitsui Marine’s life insurance subsidiary, Mitsui Mirai Life Insurance Company (later renamed Mitsui Sumitomo Kirameki Life Insurance Co. Ltd. after Mitsui Marine and Sumitomo Marine merged in 2001), Tanaka gained five years of experience in areas including product development, profit management, and risk management.

Tanaka was also a member of the loss model study subcommittee of the IAJ’s casualty committee for about three years.
