I'm not sure whether, historically, Samurai - members of the Japanese warrior caste - were supposed to always be clean-shaven or not. But I seem to recall that Samurai characters in film are mostly beardless.
How exceptional is it for Samurai characters in Japanese Jidaigeki films (period dramas) to have beards? And is it typically some particular type of Samurai characters to have them (e.g. evil vs good, old vs young, sophisticated vs. plain)?
