Kanemaru Mitsushige, a son of Takeda Nobushige, the younger brother of Takeda Shingen, founded the Kanemaru Clan and built Kanemaru-yakata. Childless, he adopted Fujitsugu, son of Isshiki Fujinao, as his son, and Kanemaru Fujitsugu took over as lord of the manor. He was followed by lords Kanemaru Torashi, and Kanemaru Torayoshi. Lord Torayoshi was followed by his son, Kanemaru Masanao, and then by his fourth son, Kanemaru Sadamitsu, whilst his second son, Masanao, and fifth son, Masatsune, became leaders of the Tsuchiya Clan. I think this high turn-over rate is due to the increasingly deadly conflicts (battle of Nagashino, &c.) which weakened the Takeda Clan.
Kanemaru Sadamitsu and Tsuchiya Masatsune followed Takeda Katsuyori to his final stand and committed suicide or were slain at the battle of Tenmokuzan. Tsuchiya Tadanao, the son of Masatsune who was just an infant when his father perished, would later become a vassal of Tokugawa Ieyasu and granted a small fief (20,000 koku). Tsuchiya Masatsune was, or had been when younger (he died in his mid-twenties), the lover of Takeda Katsuyori, leading some English language sources, notably wikipedia, to incorrectly refer to him as a woman; I wrote more about that in my profile for Taira-yashiki which I'll link below. Taira-yashiki was the where the battle of Tenmokuzan took place. Kanemaru-yakata was probably abandoned or destroyed in 1582.

Kanemaru-yakata is a fortified manor hall site which is now a temple, Chōseiin, in Tokunaga Township, Minami-Alps Municipality, Yamanashi Prefecture. It sits on a terrace of the Kamanashi River. The main fortification features of the yakata are the rear rampart of piled earth, found to the west, and indications of a karabori (dry moat). The dorui (earthen ramparts) form a long segment in the west, but there is also a corner segment and shallower segment which turns toward the cliffside in the north, indicating that this is where the yakata's northern limit was. The southern limit is suggested as being where the road now runs to the south of the temple. It's nice that this dorui segment has been moderately well preserved as part of the temple grounds.
