The kanji lettering on Buckaroo Banzai's headband as he drives the jet car reads "seikatsu-bi", which appears to be Japanese, but does not make sense. The first two kanji mean living or lifestyle, but the second character, "bi" (not "bei" as has been reported elsewhere) or beautiful, does not add up to coherent Japanese. It seems to suggest the "beautiful life" but these 3 kanji together do not have a particular meaning in Japanese.
