At just 15 seconds in length it's very short, but it's got some beautiful animation that will no doubt remind you of Ghibli's films. Nishimura acted as a producer on the project, while fellow Ghibli veteran Yoshiyuki Momose was the director. The advert shows a typical Japanese family enjoying the summer together (thanks of course to those wonderful WJRC trains!) and features some beautifully sumptuous Ghibli-esque backgrounds and some distinctly Miyazaki-style character designs. Watch the short below.
