There are actually two Kami Bands, Eastern and Western. The Eastern Kamis, the original Japanese guys, usually back them up in Japan and the rest of Asia, The Western Kamis are mostly Americans who backed them up the last time they were in America. I don't know who will be backing them up when they start touring Europe with Sabaton in April. Depends on who's available, I suppose. Personally, I prefer the Eastern Kamis, who have been with BM for the long haul.
