Death

Nobumori, however, had reportedly held frequent tea parties and seemed more interested in these rather than focusing on military affairs. He never devised, after all, any overarching military measures against the Honganji, even though their war had remained in a stalemate. It has also been recorded that since childhood, Nobumori had been openly critical of
