In Kyoto, various rumors were spread that the wife of Masamune sent to Kyoto as a hostage was the double of the real one, or the banners and flags of Masamune were put up at the castle where the ikki group was taking up a position; those rumors had reached the ears of Hideyoshi.
また、京都では政宗から京都に人質として差出した夫人は偽者であるとか、一揆勢が立て篭もる城には政宗の幟（のぼり）や旗が立てられているなどの噂が立ち、秀吉の耳にも届いていた。
