The Japanese trailer of "Harry Potter and the Half-Blood Prince" has finally made its way out. Originally aired on Fuji TV on January 17, the newly-found promotional video opens up with an introduction from the actor who portrays the boy wizard himself, Daniel Radcliffe. While most of the narration are in Japanese, the trailer still displays lots of never-before-seen footage from the adventure fantasy movie.

On another trailer news for "Half-Blood Prince", it was reported earlier that the film's final full-length trailer could be making its debut on January 23 in the U.S. theaters attached to "Inkheart". Some reports claimed that this final trailer may contain similar footage to the Japanese version, but with an English narration.

In this sixth "Harry Potter" installment, Voldemort's grip on both the Muggle and wizarding worlds is tightening. With Hogwarts no longer being the safe haven it once was, Dumbledore begins to prepare Harry for the final battle that he knows is fast approaching. Bringing in his old friend and colleague Professor Horace Slughorn, he works together with Harry to unlock Voldemort's defenses.

Meanwhile, love is in the air for the students of Hogwarts. Harry finds himself more and more attracted to Ginny, and finds out that so is Dean Thomas. While Lavender Brown has decided that Ron is the one for her, Ron gets distracted by Romilda Vane. Hermione, on the other hand, determines not to show her jealousy. Love is indeed in the air, but tragedy lies ahead and Hogwarts may never be the same again.

"Harry Potter and the Half-Blood Prince" is starred by Daniel Radcliffe, Rupert Grint, Emma Watson, Bonnie Wright, Helena Bonham Carter, Robbie Coltrane, Michael Gambon, Alan Rickman and many others. Rated PG, it is directed by "Harry Potter and the Order of the Phoenix" helmer David Yates. Warner Bros. Pictures will distribute the movie in U.K. and U.S. simultaneously on July 17.
