Translation guide
The concept of fanaticism—extreme, uncritical zeal or devotion—is expressed in Japanese through words describing obsessive enthusiasm, religious fervor, or blind belief. The most common and versatile term is 熱狂 (nekkyō), but other options carry nuances of madness, blind faith, or excessive single-mindedness.

熱狂 (nekkyō) is the broadest term for intense enthusiasm, not necessarily negative. 狂信 (kyōshin) implies irrational, often dangerous belief, especially religious. 盲信 (mōshin) emphasizes blind, unquestioning faith in a person or idea. Choose based on the nuance you need.
The English word 'fanatic' is often translated as 狂信者 (kyōshinsha) or 熱狂者 (nekkyōsha), but these can sound overly dramatic. In casual contexts, マニア (mania) or オタク (otaku) might be more natural for hobby enthusiasts.
