In which city in Japan was Hot-blooded University 2 filmed?

In Osaka, but Osaka is not so ugly, because it conforms to the times and the sense of picture described in the original book. . . Have you seen Seoul Raiders, Never Give Up, bodyguards and assassins or something? . . Then the crew will set up a trap and won't make the city so messy. You look big, but in fact it is adjusted through the lens angle, just like the scene of Terracotta Warriors and Horses Yu Shu in the movie Myth. In fact, the Terracotta Warriors and Horses rarely have perspective problems.
