Using a mixed-methods approach combining quantitative surveys and qualitative thematic analysis, the research positions families and Muslim communities as the primary agents of religious education due to limited formal Islamic institutions. The findings indicate that Islamic education is implemented through a synergy between family-based habituation of worship, faith formation, moral development, and community support through mosques, study circles, and diaspora networks. This collaborative approach is effective in maintaining basic religious practices and Islamic identity, despite challenges such as limited facilities, a shortage of qualified religious educators, and secular school influences. Supporting factors include family solidarity, active community involvement, online learning access, and hybrid Islamic education models. The study concludes that Islamic education in the Japanese diaspora context is adaptive and ecosystem based, offering a relevant model for Muslim minority communities in secular societies.otherIslamic education for childrenMuslim familiesIndonesian diasporaMuslim minoritiesJapan.Thesis
