Shiina Yasutane (?-1576) was a ruling head to the Shiina clan and son to Shiina Yoshitane throughout the latter Sengoku Period of Feudal Japan. At the time at which Yasutane ascended to headship over his respective clan in Etchu province, he used Matsukura castle as his base of primary power, simultaneously feuding with the neighboring clan of Jinbo, led by Nagamoto, lord of Toyama. These showings of disdain having taken place in the early 1550's, the Hatakeayama of Noto province had mediated between both of their clans by the year of 1554, effectively resulting in peace between both families, even though only out of rational circumstance. As Yasutane's aspirations would have it, he was able to secure a means of alliance with Uesugi Kenshin initially in 1560, ensuring the fall of Jinbo's Toyama castle by April of that same year. The power that the Jinbo possessed having been subsequently driven to nothing less than vassalship beneath the Uesugi, they were still somehow able to continue their original feud against the Shiina despite being under a higher authority, forcing Yasutane to come to the conclusion that the Takeda of Kai should be used as a necessity against such circumstances. Such an action having nonetheless driven Kenshin to the point at which he would assault and take the Shiina's Matsukura castle by the year of 1575, Yasutane petitioned the return of his domain, which proved as being a worthless course of action that provided no benefit. Having lost his base of power, Yasutane had little other choice than to become retainer to the Uesugi, dieing a year into the future out of means more than likely natural.
