Furumaya Morikane served as a bushō during the Sengoku period. He was the lord of Furumaya Castle in the Azumi District of Shinano Province.
The Furumaya were a collateral branch of the Nishina clan dating back to Nishina 盛園, the lord of Mori Castle in Shinano.
Morikane was born as the son of Furumaya Inaba-no-kami Moriharu. Moriharu built Furumaya Castle in the village of Ariake in the Azumi District of Shinano. This served as an auxiliary site for Furumaya Castle. The main branch of the Nishina clan became retainers following conflicts with the Ogasawara clan (the military governors of Shinano). Based on the strategic superiority of the Furumaya manor in the northern portion of Azumino, friction arose between the Furumaya and the Nishina. Amidst these circumstances, Morikane constructed Koiwatake Castle. Later, an invasion of the Azumi District by Takeda Harunobu (Shingen) triggered major battles.
Following the fall of Koiwatake Castle, the Furumaya surrendered to the Takeda and were able to survive as a clan. Nevertheless, after the Takeda and Nishina were extinguished, Morikane was suspected by a resurgent Ogasawara Sadayoshi of colluding with Uesugi Kagekatsu and, as a result, crushed.
