The post, shared by user @_ju_mira, featured screenshots from the Halal Japan mobile application showing various KitKat flavours—including matcha, yuzu, Tokyo Banana and sakura mochi varieties—all marked with a red “Haram LV2 (Level 2)” designation.

According to the app’s classification system shared in the thread, “Haram LV2” indicates that while the product itself may not contain prohibited ingredients, the production line is contaminated with non-halal animal derivatives.

This differs from “Haram LV1,” which refers to products that directly contain forbidden ingredients such as alcohol, pork or other haram substances.

The app also categorises products into several other levels, including “Halal LV1” for items certified by authorised halal organisations, “Halal LV2” for products free from haram ingredients and made on completely halal production lines, and “Halal LV3” for items produced on shared lines that are properly cleaned before halal production.
