Title: Houki no Kami

Vassal of the Echigo Uesugi Clan, later vassal of the Sagami Houjou Clan. He served Uesugi Kenshin along with his nephew Kawada Nagachika and participated in negotiations for the Uesugi-Sagami Alliance in 1569.

In the Otate no Ran after Kenshin's death, he declared his support for Uesugi Kagetora and took Numata Castle from Ueno Ienari of the Kagekatsu faction. He joined forces with Kitajou Takahiro to attack Sakato Castle, but retreated when Kagetora was defeated in Echigo. In order to aid the Houjou advance into eastern Kouzuke, which they were contesting with Takeda after Takeda joined Kagekatsu, Shigechika headed for Odawara.

After the destruction of the Houjou Clan, Shigechika served the Tokugawa Clan.
