McDonald's in Japan serves halal-certified food that follows strict guidelines set by the Japan Islamic Trust (JIT). The company ensures that its suppliers follow strict guidelines for halal meat production and preparation. Despite concerns about cross-contamination, McDonald's in Japan has designated separate areas for halal food preparation and uses different utensils and equipment. The demand for halal food has been increasing in Japan due to an increase in Muslim tourists and residents, leading many Japanese companies to offer halal-certified products. Halal food not only caters to Muslims but also promotes ethical and sustainable practices such as animal welfare and environmental conservation.
