On May 21, 2020, Japanese burger chain “Mos Burger” released a new menu item, the “Green Burger.”

This burger is 100% plant-based (vegan) and is available in select locations across Japan. At only 538 yen (plus tax) per burger, it’s probably the cheapest vegan burger I have ever seen in Japan.

The ingredients of the burger patty include soy protein, shiitake extract, konyaku, and cabbage. The ingredients of the green buns include vegan butter made from soy cream and spinach puree. The tomato sauce includes carrots, burdock root, herbs, and amazake.

Overall, I found the burger to be quite delicious and satisfying. Since the burger doesn’t include garlic or onions, the taste was rather mild, which is actually kind of nice for lunch because it doesn’t give you bad breath. The size is not all that big, so most people will probably want to order two unless you’re going to be eating something else alongside it.


My husband and I ended up actually going twice in the same day to get seconds because we liked it so much. Since we were cycling for several hours, we were pretty hungry. We ate a total of 7 burgers between us (3 for me, 4 for him) in two sittings.

I don’t know how long the Green Burger will be on the menu at Mos Burger, but if you get a chance to try it I recommend it! It’s still not my favorite vegan burger, but for a fast food joint I’d say it’s pretty darn good!
