He served briefly in the infantry during the First Sino-Japanese War in 1894, and afterwards assumed his family’s seat in the House of Peers of the Diet of Japan.

He retired from public life in January 1944, and died in October of the same year.

His daughter married post-war Foreign Minister Katsuo Okazaki.
