Within the Japanese reception of Huayan thought, Kegon did not fragment into numerous competing sects. Instead, it coalesced primarily around a single, dominant institutional center: the Tōdai-ji lineage in Nara. This Tōdai-ji school became the mainstream and effectively the enduring form of Kegon in Japan, shaping both its doctrinal study and ritual life. As a result, when speaking of “schools” of Kegon, the reference is usually to this Nara-based tradition rather than to a complex map of rival branches.

Other Nara temples, such as Kōfuku-ji, also maintained Kegon study and practice, but these functioned more as associated temple lineages and scholastic circles than as fully separate sects. They are often understood as part of the broader Nanto, or Southern Capital, Buddhist milieu, within which Kegon learning was cultivated. These currents reveal a diversity of emphasis and interpretation, yet they remained within a shared Kegon framework rather than forming clearly demarcated new schools. The unity of the tradition was thus preserved even amid local variations.

Over time, Kegon thought exerted a quiet but significant influence on other Japanese Buddhist traditions, including Shingon, Tendai, and various Zen lineages. Some masters drew on Kegon philosophy in combination with esoteric practices, creating interpretive currents that wove together different strands of Buddhist thought. Yet these developments did not crystallize into independent Kegon sects; they remained, instead, as cross-pollinations of doctrine and practice. In this way, Kegon functioned less as a family of separate branches and more as a single, enduring school whose vision subtly permeated the wider Buddhist landscape.
