The official Japanese website for the Supernatural the Animation project is now streaming a 34-second teaser trailer. (In the linked page, select the "Trailer" icon on the righthand side.) The acclaimed anime studio MADHOUSE (Death Note, Paprika, Vampire Hunter D, Summer Wars) is producing the previously announced 22-episode anime for Warner Brothers. Shigeyuki Miya (Lupin III: Green vs Red, Aoi Bungaku Series, Buzzer Beater) and Atsuko Ishizuka (Aoi Bungaku Series) are co-directing the project. Warner Home Video will ship Supernatural the Animation on Blu-ray and DVD in Japan on one disc on January 12, 2011, followed by two boxes on February 2 and April 6.

The original live-action series follows the Winchester brothers Sam (Jared Padalecki) and Dean (Jensen Ackles) as they hunt creatures and other supernatural phenomena across the American landscape. The series premiered on The WB network in the United States in 2005, and it will enter its sixth season on The WB's replacement network, The CW, this fall. Padalecki and Ackles confirmed at Comic-Con International last month that they are contributing to the dubbing of the anime along with their Japanese dubbing counterparts Yuya Uchida (Soul Eater's Dr. Franken Stein, Naruto Shippūden's Rinji) as Sam and Hiroki Touchi (Trinity Blood's Abel Nightroad, Bokurano's Kokkpelli) as Dean.

Update: The official Twitter account of the live-action series is also streaming the teaser trailer.
