Iwasaku and Nesaku are two kami in Shinto. They are often worshipped in star shrines in the northern Kantō region.[1]
Nesaku (根折神 – Root Splitter) is a kami in Japanese mythology. In many versions, he is from the blood of Kagutsuchi.[2] He is a minor star god.[3]
Iwasaku (石折神 – Boulder Splitter) is likewise born from the blood of Kagutsuchi.[4]
