I thought this was kinda of cool… not really related to his powers but
Once Susanou voyaged to Korea with his son Iso-takeru. Susanou got many seeds of trees, and came back. Susanou ordered his son Iso-takeru, his daughter Tumazu-hime, to plant these seeds to many places in Japan and teached how to use the trees: the cypress sould use to build a house, the ceder and the camphor tree should use to make a ship etc.
When Susanou died, his body graved the top of Mt.Kumano and his spirit became God. So he called God Kumano, later. After that, he sometimes appear as a big bear, because Japanese word 'kuma' means a bear.
Yatuka-Omizu,a son of Susanou, was a giant. Early Izumo was a small land, so he wanted to make it bigger. He made a big tight rope,and went to north sea, he found there a big island, and linked with the rope, then he returned Izumo. He put his right leg on the Mt.Daisen,left leg on the Mt.Sanbe, pulling the rope and singing,"Coming, coming, the northern island".The island moved slowly,and reached the north shore of Izumo.
Next, he went to east sea, where he found a big island, and linked it with the rope and then he returned Izumo. He put his right leg on the Mt.Daisen,left leg on the Mt.Sanbe pulling the rope and singing,"Coming, coming, the eastern island". The island moved slowly,and reached the east shore of Izumo.
Last, he went to west sea where he found big island, and linked with the rope, and then he returned Izumo. He put his right leg on the Mt.Daisen,left leg on the Mt.Sanbe pulling the rope and singing,"Coming, coming, the western island". The island moved slowly and reached the west shore of Izumo.
As though, he made Izumo as a big land.

If any one played Okami (ps2) Susanou is that big dweep with the wooden sword. Dont know much about Japanese mythology but thats pretty much all i could find on that guy.
Also whats this about a rope and pulling an island? Wasnt Oz called a Nation puller? Uh so im gonna say this outright, Oz is Kuma's son…. or Kuma is a descendant of Oz since he's from like 500 years ago. Im totally kidding (but it would be kinda cool in its own weird ass way...)
