Islam is one of the fastest-growing religions in Japan, based on percentage increase.
While Shinto and Buddhism remain dominant, Islam has experienced significant growth due to immigration from Muslim-majority countries. The number of Muslims in Japan increased by approximately 110% between 2010 and 2019, rising from 110,000 to 230,000. This growth rate, although from a small initial base, makes Islam one of the fastest-growing religions in the country by percentage.
It's important to note that identifying the "fastest-growing" religion can be complex. The term can refer to either the largest absolute increase in adherents or the highest percentage increase. In Japan, the increase in Muslim population represents a notable percentage change compared to other more established religions.
