The Church of the Light is the main chapel of the Ibaraki Kasugaoka Church, a member church of the United Church of Christ in Japan. It was built in 1989, in the city of Ibaraki, Osaka Prefecture. This building is one of the most famous designs of Japanese architect Tadao Ando.In 1999, the main building was extended with the addition of a Sunday School.Construction and structureThe Church of the Light is a small structure on the corner of two streets at Ibaraki, a residential neighborhood. It is located 25 km north-northeast of Osaka in the western foothills of the Yodo valley railway corridor. The church has an area of roughly 113 m² (1216 ft²): about the same size as a small house.The church was planned as an add-on to the wooden chapel and minister's house that already existed at the site. The Church of the Light consists of three 5.9m concrete cubes (5.9m wide x 17.7m long x 5.9m high) penetrated by a wall angled at 15°, dividing the cube into the chapel and the entrance area. One indirectly enters the church by slipping between the two volumes, one that contains the Sunday school and the other that contains the worship hall. The benches, along with the floor boards, are made of re-purposed scaffolding used in the construction. A cruciform is cut into the concrete behind the altar, and lit during the morning (as it is facing east).The work was due to problems in raising the necessary funds. Initially it was feared that it would cost more than the budget and Ando even considered building it without a roof, but the construction firm donated the roof and this became unnecessary.
