The temple bell of the Toyotomi clan had survived, but Ieyasu got angry at the inscription 'State's Peace and Health' (Kokka Anko) and 'Sovereign and subjects' Wealth and Pleasant' (Kunshin Horaku) engraved on the bell (the work of Bunei Seikan, a Zen priest of Nanzen-ji Temple in Kyoto), which he considered to proclaim TOYOTOMI as a monarch, and it is believed that he used this as a motive to destroy the Toyotomi clan (there is also the theory that Ieyasu simply wanted to create an excuse to initiate the Siege of Osaka).
豊臣氏当時ものとしては梵鐘が残っているが、この鐘に刻まれた「国家安康」「君臣豊楽」の銘文（京都南禅寺の禅僧文英清韓の作）が家と康を分断し豊臣を君主とするものだとして徳川家康の怒りにふれ、豊臣家滅亡のきっかけになったとされる（単に大坂の役の口実を家康が作りたかっただけという説もある）。
