Islam in Japan
As of 2026, Islam in Japan has established a substantive and institutionally embedded presence that has transitioned from a transient network into a durable, domestically integrated community Verified Answer #3. While the Muslim population remains a minority, it is estimated at approximately 420,000 individuals, or roughly 0.3% of the total population as of the end of 2024 Verified Answer #2Verified Answer #1. This demographic has experienced nearly fourfold growth over the past two decades, rising from approximately 110,000 in 2010 Verified Answer #2Verified Answer #1.

Demographic Profile and Identity

Mosque Infrastructure

By July 2025, there were at least 164 dedicated mosque facilities operating nationwide, compared to approximately 50 in 2008 Verified Answer #3Verified Answer #1. These facilities are distributed across 140 municipalities Verified Answer #1. Many of these spaces have evolved from informal prayer rooms in repurposed buildings into permanent, identifiable community hubs Verified Answer #3Verified Answer #1.
Institutional and Legal Integration
Islamic organizations in Japan frequently operate under the Religious Corporations Act of 1951 Verified Answer #1. Obtaining status as a "religious corporation" (shūkyō hōjin) provides these groups with a stronger legal standing to own property and operate stably Verified Answer #4.
The increased visibility of the community has occasionally led to local friction regarding urban zoning and administrative regulations Verified Answer #2. For instance, the Fujisawa mosque development in the Goshomi area faced concerns from local residents regarding traffic, noise from the adhan, and transparency in the planning process Verified Answer #3Verified Answer #1.
