EKO-Haus is a Buddhist organization belonging to the True Pure Land school of Japanese Buddhism. It was built by Yehan Numata, founder of the Mitutyo Corporation, in 1988. Construction was completed in 1993 and the temple was expanded in 1999.
The temple is modeled after Hongwanji Temple, the Jodo Shinshu temple in Tokyo. The building complex consists of the main hall, bell tower, Amitabha Hall, Sakyamuni Hall, a library, conference halls, and a Japanese garden. The main hall has a single-eave hip-and-gable roof and houses a standing Amitabha Buddha. In front of the hall there is a classic rock garden composed of dry landscaping. A statue of Prince Shotoku and a tower are located within the garden.
