Localizing into Japanese

Open setting.py from the finder. Rewrite the language and time settings on line 106 to Japanese and Japan Standard Time.

# LANGUAGE_CODE = 'en-us'
LANGUAGE_CODE = 'ja'

# TIME_ZONE = 'UTC'
TIME_ZONE = 'Asia/tokyo'

If you change the time zone and language setting and start the server again I was able to confirm that it was changed to Japanese.
