Hideyoshi installed Takatsugu at Ōtsu Castle (60,000 koku) in Ōmi province.

[4] In that same year, Takatsugu was rewarded with the fief of Obama (92,000 koku) in Wakasa Province.

The tozama Kyōgoku claimed descent from Emperor Uda (868–897) by his grandson Minamoto no Masanobu (920–993).

Takatsugu's father was Kyōgoku Takayoshi, and his mother was Azai Nagamasa's sister Maria.

However, the bakufu acted to continue his line by posthumously designating Kyōgoku Takakazu as an heir.

[1] In 1658, Takakazu was transferred to Marugame in Sanuki Province, where the contrived descendants of Takatsugu remained until the abolition of the han system in 1871.

The head of this Kyōgoku clan branch were ennobled as an hereditary viscount in the Meiji period.
