Obon (お盆) is a Japanese holiday on which observers honor the spirits of their ancestors. Within Japan as well as the Japanese diaspora, Obon has been observed on different dates since Japan’s adoption of the Gregorian Calender in 1872.

In LA and Orange County there were also Obon festivities on different dates that took place not only in several Little Tokyo venues but also in Anaheim, Gardena, Little Osaka, Venice, and West Covina. I attended the Obon Festival at Little Tokyo’s Higashi Honganji Buddhist Temple (ロサンゼルス東本願寺別院).
