Hi there!

Your latest order has trigged the review process at Gamesplanet.

Please be adviced that the game you're about to get is subject to region locks.
You will not be able to activate from Japan.

Do you want us to proceed or shall we issue a refund?
Please be warned, if we proceed, we will not be able to help you with activation issues nor will we be able to refund you anymore.

Thanks,
Chris

I heard that you can use it in Japan for comment, but is it locked?
