Deity of shinbutsu shūgō (kami–buddha syncretism)
Amaterasu Ōmikami
天照皇太神
Among the Thirty Guardian Kami, Amaterasu Ōmikami (天照皇太神) is counted as the kami who guards the tenth day. The name joins reverence for Amaterasu Ōmikami, enshrined at the Inner Shrine (Naikū) of Ise Jingū, with the system of guardian kami (banjin) who protect the Buddhist teaching. It does not merge the present-day rites of the Jingū and historical views about the original buddha into one practice.
This introduction is based on materials published by shrines, temples, and schools, starting with Shōhōin. It is summarized within the scope of the beliefs and traditions those materials convey, and does not present explanations or customs common to all schools, shrines, and temples.

Light returning from the rock cave, rice entrusted to the earth
In the myths introduced by the Jingū, light returns to the world when Amaterasu Ōmikami comes out of the rock cave, and in the descent of the heavenly grandson (Tenson Kōrin), rice to be grown on earth is entrusted. These myths convey a blessing that shines on all things and the work of nourishing people's lives.

Guarding one day at a time in turn: the faith of the Thirty Guardian Kami
The Thirty Guardian Kami (Sanjū Banjin) are a faith, combining kami and buddhas, in which thirty kami divide the days among themselves to protect the country and the Buddhist teaching. In Shōhōin's list, each kami is assigned a day from the first to the thirtieth. It is a grouping handed down in the Tendai and Nichiren lineages and others, and it needs to be distinguished from present-day explanations of the enshrined kami at shrines of the same name and from historical views about the original buddhas (honjibutsu).

Kami who come to hear the sutras — the origin story told by Shinjō-ji
Shinjō-ji, a temple of the Nichiren school, introduces a tradition that while Nichiren Shōnin was reading the Lotus Sutra on Mount Hiei, a different person visited him each day and revealed himself to be one of the Thirty Guardian Kami. This is the origin story of "the Thirty Guardian Kami who protect the Lotus Sutra" as taught by that temple. This site does not treat it as a historical event shared by all faith in the Thirty Guardian Kami.

Protection in turns that supports daily faith
Shinjō-ji introduces the Thirty Guardian Kami as guardian deities, combining kami and buddhas, who divide their duty by the day. What the temple values is the faith that they protect the Lotus Sutra and the people who believe in its teaching. This explanation is for learning their role as the Thirty Guardian Kami, in addition to the divine virtues handed down at each shrine.
