Kohei Otsuka

Kohei Otsuka took an unusual road into politics. He spent about seventeen years at the Bank of Japan and earned a doctorate at Waseda before voters in Aichi sent him to the House of Councillors four times, and he served as a vice-minister in both the Cabinet Office and the health ministry. What stays with me is the autumn of 2017: with his party splintering, he accepted its leadership, a job nobody sane wanted. He later gave up his seat to run for mayor of Nagoya and fell short. He died in March 2026. Legislatures need people who argue with numbers, and he was one.
