User blog:JsA1/What are H!P Blu-ray Disc Regions?

I'm thinking of buying C-ute 5th MV Collection, but unlike the previous collections there is no DVD version. In my country (United Kingdom) we have Region 2 DVD (same as Japan) and Region B Blu-ray (Japan has Region A). I've never bought a H!P Blu-ray disc, are they 'Region Free' or not?
