Every year, almost every company in Japan takes about a week off in August. And while some people use this time to travel, attend firework festivals, or just hang out at the beach, the real purpose is Obon, the Japanese holiday during which people go back to their hometown to visit their family grave and offer a prayer to their ancestors, whether distant or recently deceased.
In general, relatives pay their respects all together at the same time, and the associated family reunion keeps the atmosphere from being too somber. Still, in general, the tone is retrained and reserved, as the family prays silently, lights some incense, and leaves a bouquet of flowers.
Unless, that is, they’re in one of the parts of Japan where Obon means bringing a supply of fireworks or seaweed to the grave.
