[3] Nobushige nevertheless fought alongside his brother who relied on him for support, He is famous not only for his strategic insight but also his wisdom; he wrote among other things Kyūjūkyū Kakun, a set of 99 short rules or disciplines for Takeda clan members, some of which are erroneously attributed to Shingen himself from time to time.

[4] Nobushige became an important Takeda general and led large forces on several occasions.

As part of his punitive effort, he sent Nobushige to capture Fujisawa Yorichika's Kōjinyama castle.

This drove Yoshikiyo to fleet to Uesugi Kenshin and was really the last significant act before the start of the Kawanakajima campaigns proper.

[6] Noritoshi Kashima portrayed Nobushige in NHK's 2006 Taiga drama.
