and it seems the same to me, admittedly I don't know shit about Spanish.
did some searching too and it seems like Japanese can't do R's but when it comes to rolling they're decent. Japanese actually don't roll R's in normal speech though, it's only to fuck around and pretend you're in yakuza and say こら！！
Any proof of their difference cause I can't find any
