"I have some bad news for you. I have Japanese version of PRS-T2 and I also live in Japan. You can't change the language in most Sony's products bought in Japan (incl. Sony Readers, point & shoot cameras etc.) Most Sony's products bought in Japan are only in Japanese. Salesman should have warned you."
