Wood style is a mystery in Naruto world as only Hashirama had it naturally. Hashirama was reincarnate of Ashura so he had naturally strong chakra and life force. He was also a senju who are descendants of Ashura. So with this things I came up with a theory that Hashirama used water, earth and Yang release to create wood release and that's why only he was natural use. Wood release is also only kekkei genkai that creates living things other kekkei genkai create non living things except Jugo's and Kimimaro's kekkei genkai. As Hashirama is Ashura's reincarnate Hashirama's children or grandchildren would never have the ability to do it naturally as strong life force is Ashura's ability. Other members of the clan never had wood release but wood release is stated to be kekkei genkai of senju clan so previous reincarnations of Ashura must have used it.
