The season of the new year is called "shogatsu". On the last day of the year (31 December), "omisoka", practitioners usually clean their household shrines in preparation for new year's day (1 January), "ganjitsu". Many people visit public shrines to celebrate new year; this "first visit" of the year is known as "hatsumōde" or "hatsumairi". There, they buy amulets and talismans to bring them good fortune over the coming year. To celebrate this festival, many Japanese put up rope known as "shimenawa" on their homes and places of business. Some also put up "kadomatsu" ("gateway pine"), an arrangement of pine branches, plum tree, and bamboo sticks. Also displayed are "kazari", which are smaller and more colourful; their purpose is to keep away misfortune and attract good fortune. In many places, new year celebrations incorporate "hadaka matsuri" ("naked festivals") in which men dressed only in a "fundoshi" loincloth engage in a particular activity, such as fighting over a specific object or immersing themselves in a river.
