Shrines are often set within gardens, even in cities. Others are surrounded by wooded groves, referred to as "chinju no mori" ("forest of the tutelary "kami""). These vary in size, from just a few trees to sizeable areas of woodland stretching over mountain slopes. Large lanterns, known as "tōrō", are often found within these precincts. Shrines often have an office, known as a "shamusho", a "saikan" where priests undergo forms of abstinence and purification prior to conducting rituals, and other buildings such as a priests' quarters and a storehouse. Various kiosks often sell amulets to visitors. Since the late 1940s, shrines have had to be financially self-sufficient, relying on the donations of worshippers and visitors. These funds are used to pay the wages of the priests, to finance the upkeep of the buildings, to cover the shrine's membership fees of various regional and national Shinto groups, and to contribute to disaster relief funds.
