<tn>This is a phrase used by Nobunaga in a story recounted by Ōta Gyūichi in the <a href="https://en.wikipedia.org/wiki/Shinch%C5%8D_K%C5%8Dki&quot;&gt;Shinchō Kōki</a> (Nobunaga Chronicles). According to the story, when a retainer of the famous warlord <a href="https://en.wikipedia.org/wiki/Sait%C5%8D_D%C5%8Dsan&quot;&gt;Saitō Dōsan</a> Introduced Saitō (who had already retreated into monkhood at the time) to Nobunaga, Nobunaga, leaning on a pillar, responded with a simple "is that so", dismissing the great man.</tn>
