Jichinsai is the rite most Japanese people have actually attended without thinking of themselves as religious. Before ground is broken, four bamboo poles are set at the corners of the site with a shimenawa strung between them and paper streamers hung; a mound of sand stands in the middle. Offerings of rice, sake, salt, water, fish, seaweed and vegetables are laid out. The priest purifies the site and calls the kami of the land; the landowner cuts the sand three times with a wooden sickle, the designer breaks it with a hoe, and the builder levels it with a spade, each calling out. It is performed for private houses, corporate headquarters, motorways, dams and power stations, and the construction industry books it as a routine line item. It also generated a landmark constitutional case: in 1977 the Supreme Court of Japan ruled in the Tsu City jichinsai case that municipal funding of one was a secular custom rather than a religious activity, which remains the leading precedent on separation of religion and state and is still argued about.
