DMM official response in reply to Kancolle players asking them about playing the game. http://www.himeuta.net/f5-kancolle-discussion/official-response-dmm-foreigners-2452.html

As for what individual players think, who knows... Since it's RNG based anyway, it doesn't mean that if there are less foreign players, Japanese players will get more rare drops/crafts and since there hardly is any player interaction in game, I don't really see how Japanese players can be negatively affected by foreign players.

If anything, it's something better known as xenophobia. If you google "xenophobia in japan" you'll see a ton of stuff about it.
