The Japan meat substitutes market includes a variety of products that replace traditional animal-based meats with plant-based, fermented, or cultured alternatives. These products cater to a diverse consumer base, including vegetarians, vegans, and flexitarians—those looking to reduce their meat intake for health, ethical, or environmental reasons. While plant-based meats will remain the primary driver, cultured meats are expected to see increasing market share as technology advances and regulatory frameworks evolve.
