Sage mode Hashirama's technique Shinsuusenju is called a senjutsu, or sage art. My question is does Hashirama actually create the titanic wooden budda statue with Moukton (wood style) or is it a creature he summons like Naruto's sumons Gamabunta? I always thought he created it, but I've seen many people refer to it as a summons. If any1 could clarify I'd appreciate it.
According to Naruto Wiki Hashirama creates the statue using sage art wood release: true several thousand hands technique.
After entering Sage Mode, Hashirama creates a wooden statue of titanic proportions
