In The US, Disney is calling their first animated Marvel film, Big Hero 6, and will be focusing most of their merchandising around the main character’s robot, Beymax. In Japan, it looks like they’ve just gone ahead and named the whole film Beymax.

A new Japanese trailer just came out for the film, and while there’s no subtitles, the story of how Hiro Hamada gets Beymax; his is left to him after his older brother suddenly passes away.

Official Synopsis:
“Big Hero 6″ is a heartfelt comedy adventure about robotics prodigy Hiro Hamada, who learns to harness his genius—thanks to his brilliant brother Tadashi and their like-minded friends: adrenaline junkie Go Go Tamago, clean freak Wasabi No-Ginger, chemistry whiz Honey Lemon and fanboy Fred. When a devastating turn of events catapults them into the midst of a dangerous plot unfolding in the streets of San Fransokyo, Hiro turns to his closest companion—a cutting-edge robot named Baymax—and transforms the group into a band of high-tech heroes determined to solve the mystery. Inspired by the Marvel comics of the same name, and featuring comic-book style action and all the heart and humor audiences expect from Walt Disney Animation Studios, “Big Hero 6″ is directed by Don Hall (“Winnie the Pooh”) and Chris Williams (“Bolt”), and produced by Roy Conli (“Tangled”). The film hits theaters in 3D on November 7, 2014.
