Shimbutsudo (Tenzanese: 神佛道 Shinbutsudō, lit. “Way of Gods and Prajnas”) is the Tenzanese ethnoreligion, built on a systematic syncretism between regional philosophy and worship of an indigenous pantheon, with Mahagaurava Nirvanist doctrines. In Shimbutsudo, both kami (神 kami, shin, “Gods”) and hotoke (佛 hotoke, butsu, “Prajnas,” also 般若 hannya, the default word for prajnas like in Nirvanism) are revered within a single integrated cosmology. Rather than seeing the kami as merely local and overshadowed by realization of transcendence, Shimbutsudo asserts that divinity and enlightenment interact: the kami embody the raw, built-in forces of nature, lineage, and place, while prajnas and jnasattvas represent the perfected, transcendent states of awakening.

Kami of Shimbutsudo

Central to Shimbutsudo is the layered link between kami and prajnas or jnasattvas, especially through frameworks around manifestation, with the two groups understood to have specific overlaps between each other. Whether godhood or enlightenment takes precedence is implicit, with kami related to the imperial household often having their godly nature emphasized, and the most common names of a kami coming with honorifics based on their most important characteristics, according to worshipers. The most notable of kami in Shimbutsudo are:

Worshipers navigate between karmic currents, relationships with the divine, harmonious coexistence with the universe, and the search for liberation from suffering. Even with the imperial highlights, the religion remains largely pluralistic and regional, within a landscape where folklore and philosophy coexist to honor both primordial divinity and compassionate wisdom.

The Kyūsaisho and Uzansho (the two oldest Tenzanese books) hold a privileged role in Shimbutsudo as foundational mytho-historical texts, providing the genealogies and narratives that anchor the divine status of the imperial line and key kami within the national story. Alongside these, core Nirvanist scriptures such as the White Flower Sutra inform the religion's salvation and philosophy dimensions, shaping its understanding of enlightenment, karmic causality, and cosmic interdependence. Together, they form a dual canon, blending mythic legitimacy with spiritual universality.

Since its legal codification, despite no enforced absorption of Nirvanist temples in Tenzan, implicit institutional favoritism for shrines and temples declaring formally for Shimbutsudo instead of Nirvanism has eaten away at more purist Nirvanist practice, and reinforced the ethnoreligion's strength and place in the life of ethnic Uyama people, even in the years of the Rational Calendar. Nevertheless, Nirvanism continues to exist as a separate recognized religion in Tenzan.
