Mujitsu and Tairaku's Shakuhachi BBQ

Ohayo Otaku-sans!
Checked out "The Bushido Blade" 1979 with Toshiro Mifune from a friend's DVD collection.  It's a Rankin-Bass production(!?--holiday stop-gap animation fame) and a so-so film.  But it is amusing for some scenes at 38 and 42 minutes involving an 1854 procession of 7 shaku playing komuso, with authentic costuming.  The last komuso is waylaid by a Navy sailor, who goes undercover with the komuso disguise, and meets a group of sumo at a festival.  Feats of strength ensue, ending with the sailor disrobing the komuso garb in a sumo ring, and the sailor beating the sumo.  With Richard Boone in his last role, and Indonesian soft corn beauty Laura Gemser (she with the beautiful...hands, looks part Sri Lankan to me)  in the role of a self-loathing half-breed woman samurai.  Maybe she liked shakuhachi players, too!  Is this the only depiction of komuso in American cinema?
