About Japanese Buddhist pantheon

The Japanese Buddhist Pantheon designates the multitude of various Buddhas, Bodhisattvas and lesser deities and eminent religious masters in Buddhism. A Buddhist Pantheon exists to a certain extent in Mahāyāna, but is especially characteristic of Vajrayana Esoteric Buddhism, including Tibetan Buddhism and especially Japanese Shingon Buddhism, which formalized it to a great extent. In the ancient Japanese Buddhist Pantheon, more than 3,000 Buddhas or deities have been counted, although nowadays most temples focus on one Buddha and a few Bodhisattvas.
The Five Wisdom Kings is the most important grouping of Wisdom Kings (Vidyaraja)
