日本藤泽镇计划建设该地首座清真寺，引发当地居民的广泛抗议和争议[1]。这一事件反映出日本在应对快速增长的穆斯林人口和外来移民时面临的深层社会张力。
日本穆斯林人口数量显著增长，从2019年的23万人增至2024年底的约42万人[1]。与此同时，日本外来居民人口在2025年超过400万，其中创纪录的257万人在日本工作[1]。在国内人口下降的大背景下——2025年日本人口下降近100万[1]——移民已成为社会结构中的重要组成部分。日本政府在2026年6月决定将外国人签证费提高五倍，这是近50年来首次增加[1]，同时计划增加移民服务局约230名员工，加强对非法逾期居留外国人的执法[1]。
穆斯林社区指出，他们正在经历增加的社会阻力。在大阪生活39年的穆斯林商人Mohamed Mohideen称，最近几年遭遇了更多仇恨言论[1]。穆斯林领袖Shakeel Mohamed表示，穆斯林社区正努力遵守日本的规则和礼节[1]。与此同时，社交媒体上充斥着有关穆斯林和移民的错误信息[1]。
A planned mosque in Fujisawa, a town south of Tokyo, has sparked significant local controversy as Japan navigates its relationship with a rapidly expanding Muslim community.[1] The project has prompted protests and broader questions about cultural identity and integration in a nation experiencing unprecedented demographic shifts.[1]
Japan's Muslim population has grown substantially, rising from 230,000 in 2019 to approximately 420,000 by the end of 2024.[1] This expansion coincides with a surge in foreign residents overall, whose numbers exceeded 4 million in 2025, including a record 2.57 million people working in Japan.[1] Meanwhile, Japan's domestic population declined by nearly 1 million in 2025, underscoring the nation's reliance on immigration to sustain its workforce and economy.[1]
The government has responded by bolstering immigration oversight. In June 2026, it decided to increase visa fees for foreign nationals fivefold, marking the first such increase in nearly 50 years.[1] Additionally, authorities plan to expand the immigration enforcement bureau by approximately 230 staff members to strengthen enforcement against undocumented foreign residents.[1]
Within this context, tensions around the Fujisawa mosque proposal reflect deeper anxieties. Mohamed Mohideen, a Muslim businessman who has lived in Osaka for 39 years, reported experiencing increased hate speech in recent years.[1] Yet some voices within the Muslim community emphasize coexistence. Shakeel Mohamed stated that the Muslim community works to respect Japanese rules and customs,[1] while supporters of the project call for greater understanding and dialogue.[1] However, hateful rhetoric and misinformation have also circulated on social media, complicating efforts to foster integration and mutual respect.[1]
