Iwasaku (石折神 – Boulder Splitter) is a Shinto kami and the first of three kami born from the blood of Kagutsuchi after he was beheaded by the sword Itsunoohabari owned by Izanagi. The blood, caught upon the swords tip dripped down onto hallowed boulders forming this kami. This is related in the Kojiki and Nihongi.12
The name represents the power of a sword or lightning.1
