Thanks for the question Mia! Instead of worshipping deities, the object of worship in Nichiren Buddhism is the Gohonzon. The Gohonzon is a scroll with a bunch of Japanese characters that embody the Law of Nam-myoho-renge-kyo and the life state of Buddhahood, serving as a "mirror" to reflect the potential for enlightenment within one's own life. Chanting to the Gohonzon is a way to activate this inherent Buddha nature. Surrounding this central inscription are Chinese and Sanskrit characters for various Buddhas, bodhisattvas, and deities from Buddhist tradition, symbolizing all phenomena and the different states of life.
