Though it was in A.D. 1603 when Ieyasu TOKUGAWA was appointed seii taishogun (literally, great general who subdues the barbarians), the boundary between the Momoyama period and the Edo period is commonly thought to have been in A.D. 1615, when the Toyotomi clan fell in Osaka no Eki (The Siege of Osaka) and the ruling system of the Edo bakufu was established.
徳川家康が征夷大将軍に任ぜられたのは1603年だが、美術史上の区分では、大坂の役で豊臣氏が滅亡し、江戸幕府の支配体制が確立した1615年を桃山時代と江戸時代の区切りとすることが多い。
