In Japan, there are a couple of chains that exist and smaller restaurants (basically all in the areas where foreigners are and moreso near US militar bases). “Taco rice” is a local take that is basically taco ingredients served over rice instead of in a taco shell. Almost all of the places are adjusted to Japanese tastes by default, so a lot lower on the spice. Lots of foreigners living here end up going to one of a couple of places (two of which are basically Chipotle knock-offs for however “Mexican” you might consider that) or giving up and making their own. We did get Taco Bell a few years ago (again “Mexican”) which has a more limited menu. I wasn’t impressed, but I never cared for US Taco Bell, either, but it had lines lasting hours the first days/weeks it was open.
