Shimoguni Morosue (下国 師季) was a samurai, Gōzoku during Muromachi Period in Ezo. Morosue was also known as "Andō Hachiro Morosue" (安東八郎師季), as well as "Sigebetsu Shimoguni Shikibu Morosue" (茂別下国式部師季). He was the grandson of Andō Iemasa, although his father is unknown. His seishitsu was Kakizaki Suehiro's daughter.
According to "Shinra no kiroku", Morosue's grandfather, Lemasa, was the Lord of Shigebetsu castle and one of the Ezo shugos. However, one theory is Andō Sadasue, not Morosue, was the only shugo ruler of Ezo.
In Eiroku 5 (1562), due to Ainu attacks, Morosue lost Shigebetsu castle and escaped to Matsumae and was ordained as "Jōkan". As family trees show, Morosue and his son (Shimoguni Shigesue) were on bad terms, so he moved to Setanai.
After Morosue's death, his son Shigesue took over the family estate. After Shigesue's death, Yoshisue (Shigesue's younger brother's son) took over the family estate and became Karō of Matsumae domain (Shimoguni clan).
