On October 21st, Hokuto Matsumura of the popular group SixTONES appeared at a planetarium event to thank fans for the huge success of his starring film "5 Centimeters per Second" (directed by Yoshiyuki Okuyama, currently in theaters). He gave a live commentary at the planetarium at the Tama Rokuto Science Museum (located in Nishitokyo, Tokyo), which also appears in the film. After the commentary, he said, "I'm really happy to be able to hold a movie event at a place like this. I was so excited, and right before I left I thought, 'I'm so happy I got to do this,' but when I finished, I made two mistakes... I thought, 'Ah, I didn't want to do it' (laughs). If I was going to make two mistakes, I didn't want to do it."
When the MC told him that the live commentary scene had been filmed exactly one year ago on October 21st, he looked regretful and said, "Then I shouldn't have messed up."
This live-action film is an adaptation of the 2007 anime film of the same name directed by Makoto Shinkai. It depicts the protagonist Tono Takaki's 18-year life journey, from his youthful days as an elementary school student when he met transfer student Shinohara Akari and bonded with her, to his high school years on Tanegashima after being separated from Akari upon graduation, to his youth as he approaches 30, when he works as a systems engineer in Tokyo and feels a vague sense of stagnation and frustration.
Mitsuki Takahata and director Okuyama also appeared at the event.
