In the "the origin and the history of rakusui-shi production," there is a description; 'When this was first made in 1843, it did not have a name yet. When shown to the Shogun Ienari, he ordered that the name be taihei-shi (peace paper) because it was made in the period of peace.'
『楽水紙製造起源及び沿革』によると、「天保14年（1843年）初めてこれを製し、将軍家斉公の上覧をかたじけなふせしおり、未だ紙名なきを以て、泰平の御代にできたればとて、泰平紙とこそ下名せられたれ」とある。
