I believe that region 2 is Japan Mike.
SxViper is right.
It explains the region code of DVD to make sure though it is thought what you know.
From Wikipedia, DVD discs may be encoded with a region code restricting the area of the world in which they can be played.
The commercial DVD player specification requires that a player to be sold in a given place not play discs encoded for a different region.
the purpose of this is to allow motion pictures studios to control aspects
of a release,including content,release date,and,especially,price,according to the region.
region code 1s area is U.S. territories,Canada ,Bermuda.
and code 2 's area is Western and central Europe and Japan,U.K. French.
But, about Blu-ray Disc is different.
In region for Blu-ray standard,area of region A is America and East Asia.
Happily Japan and U.S.A. has the same code. waoh,Idon't have Blu-ray disc.
