Yuzaemon was Yutarou Tsukayama's father and a low-ranking samurai whose life took a sharp turn during the bakumatsu period. When the samurai class effectively dissolved, he pivoted to a new career as a merchant, dealing in Japanese katana sold as art to foreign collectors. It's a pretty typical story of that era—adapt or get left behind—though Yuzaemon found a solid niche in the sword trade.
