Koyasan Buddhist Temple, Buddhist temple in Little Tokyo, Los Angeles, United States.

Koyasan Buddhist Temple is a Buddhist temple in Little Tokyo, a Japanese neighborhood of Los Angeles. The building houses a large prayer hall and several smaller spaces designed for different spiritual activities and community gatherings.

The temple was founded in 1912 and became a central gathering place for Los Angeles's Japanese community. During World War II, it closed as Japanese Americans were forcibly relocated to internment camps, marking a painful chapter in the community's past.

The temple's name comes from Mount Koya in Japan, headquarters of the Shingon school. Each month it holds a Goma fire ritual, and the building was retrofitted for this service during a renovation begun in 1999. In 1987 it hosted the Kechien Kanjo initiation rite, rarely performed outside Japan.

The temple stands on East 1st Street in Little Tokyo, with the main hall and its 600-seat altar area on the ground floor and the Daishi-Do shrine upstairs in the annex. The basement, beneath the main altar, holds the assembly room used by Boy Scout Troop 379. Look for the Aoyama Tree, a Moreton Bay fig planted in 1920, now a city landmark.

In 1989 Los Angeles mayor Tom Bradley brought the Hiroshima Peace Flame from Japan, and the temple was named its keeper. The flame is tended on the temple grounds in Little Tokyo, far from the hypocenter it commemorates.
