Junrei (巡礼) is the word most commonly used for either of two major types of pilgrimages in Japan, in accordance with Buddhism or Shinto.
One of the most popular pilgrimages for Buddhists in Japan is visiting the 88 temples on Shikoku.
In certain contexts, Junrei can be used to refer to other pilgrimage practices in world religions foreign to Japan, such as the Hajj.
Pilgrimages can be organized by tour bus companies, taking only a couple of weeks to complete, although many pilgrims prefer to take the two- or three-month-long journeys on foot in the traditional manner.
Pilgrims on the Shikoku junrei are referred to as henro (遍路) and traditionally wear straw hats and white clothing.
