Yamamura is a very proud man he loves fishing and/or anything sea related, and himself. He seems to have a god complex, during episode four he makes Seishuu Handa write his boat name as"Yuigadokuson-Maru" meaning "I am Holy" or "I am God". Miwa Yamamura tells Seishuu that her father doesn't tolerate failure and is very frightening when he is angered.
