Identity is usually something that's in flux in coming-of-age novels, but in Heart of a Samurai, the protagonist's core identity is actually pretty constant. Identity for Manjiro is closely linked to his strong principles, so it's something that he uses to help him ride out all the worldly changes he goes through. There's still a little bit of a split or double identity since Manjiro has to straddle Japanese and American culture, but he isn't as conflicted as other immigrant characters might be, perhaps because his ultimate goal is still to go back to Japan and be Japanese—just with an American twist.
