Shakubuku in Nichiren Shōshū is understood as a method of Buddhist propagation that literally means “to break and subdue.” In doctrinal terms, it signifies breaking through what are regarded as false or mistaken beliefs and subduing attachment to teachings seen as inferior or misleading. The purpose is to guide people toward faith in the Lotus Sutra through the chanting of Nam‑myōhō‑renge‑kyō and devotion to the Gohonzon. Far from being viewed as mere argument, it is framed as an expression of compassion: an active effort to rescue others from suffering by leading them to what this tradition understands as the true Dharma.

In practice, shakubuku is carried out through direct dialogue with family, friends, and acquaintances, often beginning with simple conversations about Buddhism and personal experiences of benefit from chanting. Members explain core Nichiren Shōshū doctrines, especially the supremacy of the Lotus Sutra, the centrality of Nam‑myōhō‑renge‑kyō, and the role of the Gohonzon as the sacred mandala. This doctrinal explanation is frequently accompanied by refutation of other religious or philosophical views, pointing out what are perceived as their limitations or errors in light of Nichiren’s teaching. The method is characteristically forthright and persistent rather than passive, reflecting a sense of urgency grounded in the belief that people’s present suffering is closely tied to their beliefs and practices.

Shakubuku also has a communal and ritual dimension. Members commonly invite interested people to temple services, discussion meetings, or study sessions, where they can hear further explanations and observe the practice of chanting Nam‑myōhō‑renge‑kyō. Personal testimony plays a significant role: practitioners share concrete examples of how their faith and practice have transformed their lives, thereby giving experiential weight to doctrinal claims. Through such ongoing interaction—dialogue, explanation, refutation, and invitation—shakubuku becomes a continuous effort to encourage others to abandon what are seen as mistaken paths and to embrace Nichiren Shōshū faith as the means to enlightenment.
