To change your language settings on a Windows PC:

3. Select the General tab.
4. On the Language pop-up menu (in the lower section of the window), choose your desired language.
5. Click OK.

iTunes must be restarted for your new language setting to take effect.

ask someone who speaks and writes japanese and ask them what everything says and what says "change language" or "settings'' or something like that
