ICYMI: Rupan Sansei is in full kabuki mode through almost its entire run, with language that tends to be just as inscrutable for Japanese speakers as Shakespeare can be for English natives. Still, the characters shine through.
Despite its very 70s vibes, international settings, and jazzy music, Lupin often features deep Japanese cultural pulls. Transposing the action to late 16th-century Japan works more easily than you might imagine.
