The PlayStation 3 (PS3) comes with 17 languages pre-installed to the system that can be changed at the discretion of the user. If the language setting on your PS3 is currently set to Japanese, you have the ability to go into the console settings and change it to English. Once the language is changed, everything on your console, including the online menus of the PlayStation Network (PSN), will change to English.
Turn on your PS3 console and press the middle “PSN” button on your controller.
Select the first option in the list (the option is “Settings” in English) and then select the first option in the next list (the option is “System Settings” in English).
Scroll down to the “Language” icon and select “English” from the list of languages. Confirm the change when prompted and return to the main menu. Your PS3 and PSN language has now been changed from Japanese to English.
