The English word 'irreligion' is formal and rarely used in conversation. In Japanese, 無宗教 (mushūkyō) is the closest term but is also somewhat formal. In casual speech, people often use phrases like 宗教に関心がない (I'm not interested in religion) or simply state they have no faith.
Many Japanese people identify as 無宗教 but still participate in Buddhist and Shinto rituals. This is often described as 'cultural religion' rather than personal belief. When discussing irreligion in Japan, it's helpful to clarify whether you mean lack of belief, lack of affiliation, or indifference.
