Hattori Hanzō
Quentin Tarantino stated in the supplementary material on the "Kill Bill" DVD that the character was named in tribute to Chiba's former role as Hattori Hanzō (the historical 16th-century Iga ninja) in "Shadow Warriors (Kage no Gundan)". The joke is that Chiba played multiple generations of the character: when the character died, the next installment would shift to covering his descendant, also named Hanzō after his famous predecessor. The implication is that the character in "Kill Bill", whom Tarantino called Hattori Hanzō XIV, is another descendant of the same lineage. Chiba's daughter Juri Manase also appears in "Kill Bill" as a member of the Crazy 88. A digitized version of a promo image for the series' second season infamously appears on the title screen of The Revenge of Shinobi.
