Sami Mansei

Sami Mansei, was a Japanese Buddhist priest and poet. Little is known of his life except that his secular name was Kasa no Ason Maro. While serving at a temple in the north of Kyūshū, he was a member of Ōtomo no Tabito's literary coterie. His few surviving pieces are collected in the Man'yōshū.
Mansei is famous for the following waka poem from the Manyoshu:
Yononaka-wo Nani-ni Tatohemu Asa-biraki Kogi-inishi Fune-no Ato-naki-gotoshi
which means ''All are to disappear, just as the morning boat wake does.''
