Well both of them have white hair, so of course they must be relatives. I guess they're brothers or so. And since Kaneki is Arima's brother (there are just too many plausible fan made theories to deny this obvious fact), that also makes Kaneki and Tatara brothers, which makes perfect sense. And Dr. Kanou is secretly their father. And Noro is Aizen.

Jokes aside, I doubt that Tatara and Arima are related in any way.
