Who is Joman from The Master Puppeteer and what is their importance?

Joman is the fictional bandit in the play The Thief of the Tokaido. He is clearly meant to be similar to Saburo, to make the audience feel sympathy for Saburo. Like Saburo, he is wily and brave, and makes the merchants and the authorities look like fools. In the play, Joman is betrayed by his own wife. The audience feels despair at this and at the end of the play, Saburo reminds them that they should feel the same despair at the thought of anyone betraying him.
