Niten Ichi-ryū
In 1976, Kiyonaga Tadanao died suddenly, without leaving a designed successor. As Soke Daiken, Gosho Motoharu continued to represent the "ryū" on this period. After eight months without a "soke", the Kiyonaga family asked Gosho Motoharu to prepare Imai Massayuke, a Kendo teacher of the same town, who made contact with the style months earlier interested in learning more about the Bōjutsu of the Niten Ichi-ryū, to stay as 10th "soke", while the son of the 9th Soke, Kiyonaga Fumiya, would be the 11th "soke".
