In 1670 when Yasutomi passed the genpuku ceremony and was designated as Shorokuinoge Kurodo (Senior Sixth Rank, Lower Grade, Chamberlain) and Konoefu (the Headquarters of the Inner Palace Guards), the disputes occurred again with Tomohiro KOTOKUI regarding Onmyoji no kami, however, Tomohiro died suddenly at the age of 35 in 1682, and the Edo bakufu shogunate which arbitrated the conflicts handed down the ruling that the son of Tomohiro was too young to execute the post, thus Yasutomi who was at Jugoinojo Hyobu-shoyu (Junior Fifth Rank, Upper Grade, junior assistant minister of the Hyobusho Ministry of Military) acceded the post, and in the next year, he was authorized to control and license the Onmyoji of the whole country.
泰福が元服して正六位下蔵人兼近衛府に任じられた寛文10年（1670年）にも泰福と幸徳井友傳の間で陰陽頭を巡る相論が発生するも、天和_(日本)2年（1682年）に友傳が35歳で急死、相論の仲裁にあたっていた江戸幕府は友傳の子は幼くて職務が行えないと裁定したため、当時従五位上兵部少輔であった泰福が陰陽頭に就任、継いで翌年には諸国の陰陽師を支配・免許の権限が与えられた。
