This is the annual festival at my son’s preschool and was held on July 17. I thought it was kind of strange to have an Obon festival in July because the Obon holidays are in August, but apparently, the festival gets celebrated at different times in Japan.
In Tokyo and Tohoku (northern Japan), it’s celebrated in July and is called “Shichigatsu Bon” (literally July Bon), but in Kansai and most other areas, it’s called “Hachigatsu Bon” (August Bon) and is celebrated on the 13th, 14th, and 15th of August. The reason is that it was originally based on the lunar calendar, and when Japan converted to the Gregorian calendar, some regions kept celebrating it on the old dates while others switched it to the modern calendar. In fact, there are even a few places that still celebrate kyu-bon (the old Obon), so it falls on a different day every year depending on the moon.
I really enjoyed the dancing and other events, and if you’re ever walking by a preschool and you see a festival going on, you should definitely stop in because it’s really photogenic. All the kids dress up in yukata and jinbei, and they’re really cute when they dance.
