there is no proof that anyone other than hashirama had ever had wood release. sure its called a kekkei genkai of the senju clan but any normal senju would never be able to even attempt wood release as it would instantly over power and kill them only asura's transmigrants have the required life force to use wood release so if anyone else had wood release than they were transmigrants Hashirama use Wood Release Secret Technique: Nativity of a World of Trees, this jutsu is "Hiden". Hiden or simply "secret" techniques are passed down orally from generation to generation in certain regions or clans. Then this technique has been passed down to Hashirama by a member of his clan who owned WR.
