Sure, kind of. Gate, for instance[0], an anime about the JSDF encountering a portal that opens to a medieval fantasy world, contains a lot of nationalistic and pro-military themes. Kantai Collection, an anime based on a game, features IJN ships as heros, and some historical revisionism[1]. I can't think of more off the top of my head. It doesn't seem to be a common theme but it's entirely possible I as a typical Western weeb just don't see it. A lot of anime set in the future portray Western powers in a negative light - the American Empire in Ghost in the Shell Stand Alone Complex is clearly villainous - but I don't know if that's "right wing" or just reasonable extrapolation.
It seems to be more common to discover the creators of an anime or manga holding right-wing or extreme beliefs, though, than for those to explicitly find their way into anime. The director of Recovery of an MMO Junkie, for instance[2] with his anti-semitic tweets.
