it is not yet known but there are theory's.
One is that he dug up Obito and got the sharingan from him. no one from Konoha would do this so he could have gotten the transplant from orochimaru. but i think that is unlikely because orochimaru wanted the sharingan himself. This may not be true because Obitos body was completely crushed.
Another theory is that orochimaru made a sharingan and gave it to danzo for testing purposes. But this is too far-fetched to believe.
Another is that Danzo is Obito which would would explain why one of his sides is wrapped and he got a normal eye from somewhere else (Obito gave one of his eyes to kakashi.) but Obito would be too young because danzo held a grudge against the 3rd hokage.
My theory is that Danzo has a connection with "tobi" or madara. tobi only shows one of his eyes through his mask so it is possible that madara gave his other eye to danzo in an agreement. I don't think that this is the case though.
We will just have to wait and see.
He Got it From Obito when he was on a mission when he was younger. Obito got crushed by a rock and gave kakashi his Sharingan as a gift before he died. Obito had the Sharingan because he was an Uchiha.
Danzo only has 1 sharingan eye on his right side also he has some kind of special arm (his right arm also) his sharingan first shows on naruto shippuden episode 199 but it only shows for a few sec when he kills these assassins with his eye.
He wasn't born with Sharingans. He collect Sharingans from the Uchiha Massacre and by the help of Orochimaru he implanted Sharingans in his hand and one eye along with First hokage cell for chakra.
behind Danzo's mask is what Danzo absorbed out of Uchiha Shisui.
When Danzo held Karin hostage, Sasuke used this opportunity and sacrificed Karin by stabbing her with his "Chidori Spear" to get Danzo through the heart. Within his last few minutes of his life, Danzo used his final Jutsu called "Reverse Four Symbol Sealing" in hopes of sealing Madara and Sasuke along with him in his death, but it failed since Sasuke and Madara got away from it in time and Danzo ended up in suicide.

Sasuke's sharingan is stronger, he beats Danzo... - Sasuke's sharingan surpasses Danzou olnly because the sharingan is a bloodline limit and danzou does not posses enough chakra to fully use the all of the sharingan , do you want me to explain how danzou obtained so many sharingans ?

Use lenses or photoshop
Yes, Danzo is an Italian word.
The same as all Sharingans
NO.....danzo and Tobi are not the same person though most people belive it to be so.........
Danzo wants to kill sasuke but Sasuke is stronger than him
Hel will have 2 his own and Itachi's

No because Danzo is a different ninja that uses unknown jutsus to fight others...
