Nenshitsu Yokaku

Nenshitsu Yokaku (1440–1516) was a late-Muromachi Sōtō master who received Dharma transmission from Mugai Keigon (1436–1517) and passed it to Sesso Hoseki, bridging two decades of the *Sengoku* civil wars era. His years of active teaching — roughly the last quarter of the fifteenth century into the early sixteenth — coincided with the period of maximum political fragmentation in Japan, when provincial warlords displaced the Ashikaga shogunate's authority and Buddhist temples had to negotiate survival within a landscape of constant military competition^[1].

For the Sōtō school, this period paradoxically reinforced the strength of the provincial network: as Bodiford observes, rural Sōtō temples had long served the memorial and mortuary needs of warrior families, and local warlords often protected these temples even as they fought each other. Nenshitsu's generation of abbots maintained the transmission chain precisely because the school's social utility — its role in funerary Buddhist practice — insulated individual temples from the worst of the violence and ensured continued lay support regardless of which military power held local authority^[1].
