Tomioka's Father is how captions credit the father of Tomioka Tessai in his appearance in I Am Tomioka Tessai.
This refers to Tomioka Korenobu, a seller of sacerdotal robes. Korenobu actually died in 1843, a year prior to the Riddles' arrival in 1844, so either he was a ghost or this was some kind of mistake and he didn't die as early in the timeline of this series (perhaps due to historical alterations made by the Riddles) as he did in our reality.
