Also known as: Ijimino Harunaga (五十公野治長)
Title: Inaba no Kami

Brother of Shibata Nagaatsu, a vassal of Uesugi Kenshin, who served Kenshin during the Battle of Kawanakajima. He was persuaded by Yasuda Akimoto to join Uesugi Kagekatsu in the Otate no Ran after Kenshin's death and took down Kaji Hidetsuna of the same clan (his clan is an illegitimate offshoot of the Kaji Clan) who had joined Kagetora.

Dissatisfied with his reward after the war, Shigeie turned to Oda Nobunaga. About six years later, Kagekatsu's army destroyed his troops, and he committed seppuku.
