Bored Hatamoto Detective, Part 2: Poisoning of the Demon Lord (1950)

This was the ELEVENTH film in the Bored Hatamoto series — Utaemon Ichikawa played this character from 1930 to 1963, making him Japan's original exhausted detective archetype decades before Columbo.

The 'bored hatamoto' trope satirized the Tokugawa-era warrior class — samurai with stipends but no wars, drowning in leisure and intrigue. It's basically Downton Abbey with more beheadings.
