Take a trip to Kawaguchiko in Yamanashi prefecture for the Kawaguchiko Kojo Matsuri summer festival, which takes place on Monday August 5. You'll be able to see fireworks launched from the middle of the lake between the eastern shore and Kawaguchiko Bridge. The gigantic starmines will not only be reflected on the water’s surface but also synchronised to music.
For an up-close view, head to Oike Park or either one of these two shores – Funatsuhama and Hirahama. Between Oike Park and the Komagari Tunnel lakeside, dozens of food stalls will line the street, selling typical festival grub.
Pro tip: if it’s a clear night, make a beeline for the other side of the lake, around Nagasaki Park or Oishi Park. Here you’ll have an uninterrupted view of the fireworks, with the towering silhouette of Mt Fuji in the background.
