Samsung usually adds a T to model numbers of devices that are either headed for T-Mobile in the USA or Telstra in Australia, so the SGH-075T could be headed for either of those markets, or it could be specific to Taiwan as well. However, it's quite uncommon for Samsung smartphones launched for Japanese carriers to get an international launch, but this could be an exception, though we'll have to wait for more information to find out where Samsung is planning on launching the considerably upgraded Galaxy S4.
