Gotō Katatoyo served as a bushō during the Sengoku period. Katatoyo was an accomplished and highly popular retainer of the Rokkaku clan based at Kannnoji Castle in the south-central part of Ōmi Province. The Rokkaku were the sengoku daimyō of southern Ōmi.
Katatoyo was born the son of Gotō Tajima-no-kami who also served as a retainer of the Rokkaku in Ōmi. Katatoyo received one of the characters in his name from his lord, Rokkaku Yoshikata.
The Gotō clan of Katatoyo and the Shindō clan of Shindō Sadaharu and Shindō Katamori were known as the “Two Tō of the Rokkaku” for being powerful veterans of the clan. The smart and courageous Katatoyo participated in attacks against the Azai clan under the command of Yoshikata.
In 1559, Katatoyo served along with the Gamō clan as honorary magistrates, and, in 1562, participated in a march to Kyōto by Yoshikata, serving as security for his lord at the Daitoku Temple.
Rokkaku Yoshikata retired in 1559 and transferred the headship of the clan to his son, Rokkaku Yoshiharu. Nevertheless, Yoshikata continued to exercise his influence from behind the scenes. On 10/1 of 1563, Yoshiharu ordered Tanemura Michinari (Mikawa-no-kami) and Takebe Hyūga-no-kami to murder Katatoyo and his son, Gotō Iki-no-kami, inside Kannonji Castle in an incident known as the Kannonji Disturbance. There are assorted theories as to the reason for this action. From the era of Rokkaku Sadayori (Yoshiharu’s grandfather), Katatoyo was very popular within the Rokkaku family as a meritorious retainer, and he was well-trusted by the retired Yoshikata. After a power-struggle based on Katatoyo’s authority (with Yoshikata’s authority in the background) and the youthful Yoshiharu, Yoshiharu may have ordered the killings to solidify his leadership as head of the clan. The event was so significant that it was a contributing factor to the downfall of the clan.
Katatoyo was succeeded by Gotō Takaharu, his second son.
