The origin of Bon is from the Buddhist observance in China, and was introduced to Japan in the seventh century. For religious reasons, people believe that ancestors' spirits come back to their home during the Bon Festival. The Toro Nagashi is another rite to see off ancestors' souls. Today, Bon season has become a family gathering time since people who live outside of their hometown return home during that time. Many companies provide employees with a week Obon holiday.
Some people use the holiday and go on trips in Japan or other countries.
