it doesnt matter if you buy a japanese ps3 or american they both play blu ray movies & games vice versa because they are region A, except ps2 games on slim models. also the old 20gb & 60gb japanese ps3 have back words compatibly for example jap ps3 20 or 60 region A for all blu ray & games & japanese ps2 games for jap system & same applies for american 20 & 60gb but with american ps2 bc not jap ps2 though hope that helps & if you have an external hdd you can install ps2 games on those just use google
