Komai-yashiki was the medieval fortified residence of the Komai Clan. The clan was established by Komai Nobumura, the fourth son of Takeda Nobumasa, after he received a fief in Komai. The lord of Komai-yashiki held the honourific title of Ukyō no Daibu (High Steward). Under the rule of Takeda Shingen, the lord of the manor was Komai Masatake. His son, Komai Masanao, became the new lord of the manor and would go on to become the castellan of Fukazawajō in Suruga until 1582. There is an important historical document relating to the Takeda Clan called the Kōhakusaiki. Komai Masatake is thought to have been the original author of that Sengoku period document, so I would suppose it was likely written at least in part at the Komai-yashiki.
At the rear of a fine, old rural home in the Komai area of Fujii Township, Nirasaki Municipality, is a bamboo grove. This grove, which forms a long border a the back of the home, is actually a long segment of dorui (earthen ramparts). It is 2m tall or more in places, but it is difficult to photograph as it is covered in bamboo. The dorui represents the ruins of the Komai-yashiki. The old residence itself, though a much later structure, is also the inheritor of the Komai estate. The current residence has a nagayamon (row-gatehouse) which may date to the Edo period. The omoya (main residence) also may be from that time as it is built in the vernacular style of Kai. The house is still occupied and not open to the public.
It seems some castle bloggers have missed the dorui, which is behind the residence, but in fact there is a small back road which follows the dorui along, and I was able to get a good look there. I was quite impressed with the old fortification structure, but I worry my pictures don't show it well...
