It's highly likely he started a family later on in his life (somewhere between 300-400 years old). If Tsumuji is about the same age as his actor (44/45), then the Last Ninja/Yoshitaka started a family around 1970 (or between 1960-80) then around 1980, he trained both Tsumuji and Kyuemon (Kyuemon was sent into the future by his father, Gengetsu, and the Last Ninja trained both Kyuemon and Tsumuji when they were teenagers).
