During the Battle of Osaka in 1615, Muneyoshi KIMURA, who served Oribe as his tea ceremony master, was arrested by Katsushige ITAKURA of the Kyoto deputy on charge of having organized a conspiracy in collaboration with the Toyotomi clan to set fire to Kyoto (Some people believe that he intended to assassinate Ieyasu by taking advantage of the disturbance caused by the fire).
1615年（慶長20年）の大坂の役のおり、織部の茶頭である木村宗喜が、豊臣氏に内通して京に放火（混乱に乗じて家康暗殺を意図した説がある）を企んだとされる疑いで京都所司代の板倉勝重に捕らえられた。
