Obon (お盆) or just Bon (盆) is a fusion of the ancient Japanese belief in ancestral spirits and a Japanese Buddhist custom to honor the spirits of one's ancestors. This Buddhist custom has evolved into a family reunion holiday during which people return to ancestral family places and visit and clean their ancestors' graves when the spirits of ancestors are supposed to revisit the household altars. It has been celebrated in Japan for more than 500 years and traditionally includes a dance, known as Bon Odori.

The festival of Obon lasts for three days; however, its starting date varies within different regions of Japan. When the lunar calendar was changed to the Gregorian calendar at the beginning of the Meiji era, the localities in Japan responded differently, which resulted in three different times of Obon. Traditionally, Obon was celebrated on the 15th day of the seventh month of the lunar calendar.

Obon is now observed during one of the following periods:

• July 15 of the Gregorian calendar (Shichigatsu Bon or "Bon in July"): Observed in Tokyo and some urban areas of the Tōhoku region and Hokuriku region regions where agricultural busy seasons do not overlap with the festival dates. This practice is sometimes referred to as "Tokyo Obon."
• August 15 of the Gregorian calendar (Hachigatsu Bon or "Bon in August"; Tsukiokure Bon or "Month Later Obon"): This is the most commonly celebrated time across Japan.
• 15th day of the seventh lunar month (Kyū Bon or "Old Bon"): Observed in Okinawa and the Amami Islands, this version follows the lunar calendar, so the dates change yearly on the Gregorian calendar, sometimes extending into September.

These days are not listed as public holidays, but it is customary for people to be given leave.
