Thirteen Buddhas

The Thirteen Buddhas (十三仏, Jūsanbutsu) is a Japanese grouping of Buddhist deities, particularly in the Shingon sect of Buddhism. The deities are, in fact, not only Buddhas, but include bodhisattvas and Wisdom Kings. In Shingon services, lay followers recite a devotional mantra to each figure, though in Shingon practice, disciples will typically devote themselves to only one, depending on what the teacher assigns. Thus the chanting of the mantras of the Thirteen Buddhas are merely the basic practice of laypeople.
