If you buy a Sony or Sharp phone used, high chance it's going to be locked to a Japanese carrier as that's just where Sony and Sharp are popular.

NTT Docomo (and associated MVNOs) do not allow you to unlock your bootloader, the OEM unlock option is greyed out.

OEM unlocking works fine, however [it seems that Fastboot is modified.](https://www.reddit.com/r/SonyXperia/comments/15qdxt2/bootloader_unlocking_trouble_for_softbank_xperia/)
