Richard Nikolaus Eijiro Coudenhove-Kalergi was born in 1894. He was the son of Heinrich Coudenhove-Kalergi and Aoyama Mitsuko. Since he was born in Japan and his mother was Japanese, he was given the Japanese name of Eijiro as one of his middle names, hence his Japanese name during his childhood in Japan was Aoyama Eijirō (青山 榮次郞/栄次郎, あおやま えいじろう), with Aoyama being his mother's family name by birth. He died in 1972.
