Takeda Nobuchika
, also known as (1541–1582) was the second son of Takeda Shingen. He lived during the Sengoku period in Japan. He was born completely blind and therefore could not become a retainer of the Takeda clan. Instead, Shingen named Nobuchika heir to the Unno clan of Shinano province, in order to further expand his influence. When the Oda/Tokugawa alliance invaded Kai province in 1582, Nobuchika committed suicide by taking hemlock. Tokugawa Ieyasu, who had felt sympathy towards Nobuchika, protected his son from harm after his death.
