According to rumors that Tsunade had heard, Shoton can crystallize any substance, thus, Earth, Water, and Wood techniques are useless against it. Using Crystal Ninjutsu, the user can crystallize any physical material and even the moisture that is present in the air around them, turning them into a weapon. In the case of human targets, Shoton can solidify its targets down to the cellular level, imprisoning and even killing the victim should the crystal ever be struck, reducing the mass of crystal and the victim down to crystalline dust.
The only apparent weakness of the Shoton is that it cannot crystallize either raw energy or chakra as they have no physical mass to crystallize, allowing a person with either energy-based Jutsu, such Wind, Fire and Lightning releases, or good chakra control to properly counter it. Shoton is also susceptible to a specific sound wave frequency; because crystal requires a very precise build-up of molecules, the proper sound waves can break down the build-up before the crystal can properly form. Rinji, taking advantage of this weakness, used his Ninja-Bats to counter Guren's crystal attacks.
