It is said that this and the time when Oishi met Yozenin during his first trip to the east were the inspiration for the story 'Nanbuzaka Yuki no Wakare' (the parting in the snow at Nanbuzaka) which talks about Oishi meeting Yozenin just before the raid to say their last good-bye in their present lives.
このことと第一次大石東下りの際に大石が瑤泉院に拝謁したことがヒントとなって討ち入り直前に大石が瑤泉院に拝謁し、今生の別れをするという「南部坂雪の別れ」の逸話（後述）が生まれたといわれる。
