Sometimes on Japanese films when someone says "I'm sorry" they say what I hear as "sumano", what is the actual word they are saying? And is it short way of saying I'm sorry?
i heard "Yoshida Zengo" say it in the 1970 film Tora! Tora! Tora! he says it when he is speaking to Yamamoto Isoroku in the Japanese Navy ministry about the Teikoku Rikugun and being unable to successfully fight Army militaristic and Pro-Axis policies
The man who played him looked rather old, like he was in 50s or 60s, ive looked on wikipaedia and he was played by "Junya Usami"
