Smash Bros. DOJO!! is the official website for Super Smash Bros. Brawl. It is available in many languages; English (both American and British), Japanese, German, French, Spanish and Italian.
Taking the form of a Blog written by Masahiro Sakurai, the site is currently being updated each weekday with new information on characters, stages, items, music and other aspects of the upcoming game. See Smash Bros. DOJO!! updates for full details. The headline for each update is accompanied by the universe symbol corresponding to the subject of the update; for example, Link's profile shows the Triforce, and Mario's shows a super mushroom. Things originating in the Super Smash Bros. Universe are accompanied by the Smash Bros. logo.
The updates usually occur at midnight Pacific time, though they have been late in the past, sometimes by hours. This is rare, however.
