Not even morningstar farms veggie burgers in grocery stores. But that was 10 years ago, things are different now.
Whenever I go home for Christmas I'm amazed at what's available.
Before moving in, I used to think it should be easy to be vegetarian in a Buddhist country but it is not. Japan's culinary habit is that a good meal needs to have a lot of different ingredients in it. From a dietetics point of view, that's great but it often means that even in most salads, you'll have a few pieces of bacon or chicken, a shrimp or some grains of minced meat.
That still makes for a very meat-light diet and I would switch to a no-meat-at-all in a heartbeat if those bentos and salads came in vegetarian versions, but that makes it almost impossible to totally avoid meat.
I'm interested in food insecurity and related things, which is why I ask.
