Incidentally, some say that a child of Katamochi MIKUMO, Shigemochi's elder brother, is the model for Sasuke SARUTOBI, a ninja well known for being one of the Sanada Juyushi members (Sanada ten braves) (see the section for Sasuke SARUTOBI for further details).
ちなみに彼の兄・三雲賢持の子が真田十勇士で有名な忍者、猿飛佐助のモデルであるとする説もある（詳細は猿飛佐助の項目を参照）。
