Japanese wrestler Sakamoto has reportedly been re-signed by WWE. He was last seen as an assistant for Tensai and was released in May 2013. He was at Friday night's NXT event in Orlando and has been in the area for days.
There are some who claim that Sakamoto was brought in to help translate for KENTA when he arrives. However, this should be taken as just a rumor as it's not 100% confirmed that KENTA will even debut for WWE.
