Ashikaga Yoshitane

, also known as , was the 10th shōgun of the Ashikaga shogunate who headed the shogunate first from 1490 to 1493 and then again from 1508 to 1521 during the Muromachi period of Japan.

Yoshitane was the son of Ashikaga Yoshimi and grandson of the sixth shōgun Ashikaga Yoshinori. In his early life, he was named Yoshiki (sometimes translated as Yoshimura), and then Yoshitada — including the period of when he is first installed as shōgun; however, he changed his name to Yoshitane in 1501 in a period when he was temporarily exiled, and it is by this name that he is generally known today.

The 9th shōgun Ashikaga Yoshihisa died in 1489 on a battlefield of southern Ōmi Province. Yoshihisa left no heir; and Yoshitane became Sei-i Taishōgun a year later.

Events of Yoshitane's bakufu Yoshitane was appointed shōgun in 1490. Hōjō Sōun gains control of Izu the following year. In 1493, Hatakeyama Yoshitoyo forced Yoshitane to abdicate after he lost in a power struggle against Hosokawa Masamoto.

Emperor Go-Kashiwabara acceded to the throne in 1500. Ōuchi Yoshioki restored Yoshitane to the position of Sei-i Taishōgun from Yoshizumi. In 1520, a succession crisis occurred over Hosokawa Takakuni's post. When Takakuni became Kanrei (shogun's deputy), Yoshitane strongly opposed him and he was driven out.

Yoshitane's heirs and successors Shōgun Yoshitane adopted the son of Yoshizumi who was his cousin, Ashikaga Yoshitsuna and he designated Yoshitsuna as his heir and as his anticipated successor as shogun. However, when Yoshitane died prematurely, he was not succeeded by who he had chosen; rather, his father's newly designated heir was accepted by the shogunate as shōgun Yoshizumi.

In other words, after the death of his son, shōgun Yoshimasa adopted the son of his brother, Yoshimi. After the death of his adopted son, Yoshimasa adopted the son of another brother, Masatomo. Shogun Yoshimasa was succeeded by shōgun Yoshihisa (Yoshimasa's natural son), then by shōgun Yoshitane (Yoshimasa's first adopted son), and then by shōgun Yoshizumi (Yoshimasa's second adopted son). Yoshizumi's progeny would become shōguns in due course. Entoku (1489–1492) Meiō (1492–1501) Bunki (1501–1504) Eishō (1504–1521) Daiei (1521–1528)
