I wasn’t aware that Mr. Hosokawa was such an accomplished artist. As I think most of you know, he is a descendant of Hosokawa Tadaoki, who replaced Kato Tadahiro (Kato Kiyomasa’s son) as lord of Kumamoto in 1632. He is the only former governor of Kumamoto I am aware of to have become prime minister in the postwar era . – Kirk

P.S. Thanks to Kazuhiro Oyama for telling us about Kiyoura Keigo, who was a prime minister in the 1920s. (See comments)
