 After the Hōkō @-@ ji temple burned down at the start of the seventeenth century , Toyotomi <unk> sponsored its reconstruction in 1610 , and commissioned a large bell as part of that process . The bell 's inscription drew the ire of Tokugawa Ieyasu , who had become shogun after wresting power from the Toyotomi clan when <unk> 's father Hideyoshi died . The inscription , " Kokka <unk> " <unk> ( " Peace and tranquility for the nation " ) , broke up the characters for the shogun 's name ( <unk> ) with the kanji character for " peace " ( <unk> ) . Tokugawa assumed Toyotomi was implying that peace would require the " dismemberment " of the Tokugawa . He used the subsequent dispute as an excuse to wage war on the Toyotomi clan , resulting in the Siege of Osaka and the eventual destruction of the Toyotomi .
