The way he danced the Seigaiha play was described in detail in diaries including "Gyokuyo" (Kanezane KUJO's diary) and "Angen Onga no Nikki" (the record of the ceremony celebrating Cloistered Emperor Goshirakawa's 50th birthday), where FUJIWARA no Takafusa, who attended the ceremony, describes the scene as 'Koremori comes out and dances a Rakuson dragon dance in the Iriaya style, wearing a blue Uenokinu coat and an Uenohakama kilt that matched his complexion, his expression, and his aura, which filled the atmosphere and fascinated the audience; the beauty and magnificence of his dance was no less than those of the cherry blossoms he was wearing.'
青海波の様子は『玉葉』や『安元御賀日記』などにも詳細に記されており、臨席した藤原隆房はその様子を「維盛少将出でて落蹲（らくそん）入綾をまふ、青色のうえのきぬ、すほうのうへの袴にはへたる顔の色、おももち、けしき、あたり匂いみち、みる人ただならず、心にくくなつかしきさまは、かざしの桜にぞことならぬ」と書いている。
