Decades in the Making, The New Plant-Based Green Burger from Mos Burger Japan Is for Everyone!

Japanese hamburger chain Mos Burger is back on the scene with the Green Burger, and thanks to its new plant-based recipe, this burger is going to win a lot of hearts. As soon as we set eyes on its pale green bun, the JAPANKURU team knew we had to find out more about it.

The Green Burger's History

Mos Burger was founded in 1972, with dreams of making food that everyone can enjoy, and using good, natural ingredients while they were at it (as you can tell from the MOS, which stands for Mountains Ocean Sun).

Due in part to their popularity, in recent years the Japanese burger joint has been compared to other enormous, multinational fast-food chains. When asked, though, Mos Burger rebels against this comparison. Their intentions aren't just to make food that is fast and cheap, they say, but to make good food, for any customer who walks in the door.

Which is where their newest offering, the Green Burger, comes into play. Every burger made at a Mos Burger shows off the results of using high-quality ingredients, but the latest in food technology opened up a new world of options to look into. With new innovation, 2020 became the perfect time to make the fresh, new Green Burger: delicious, plant-based ingredients, all in one convenient Mos Burger package.

Plus, since Mos Burger has been implementing sustainable methods and working towards green policies since the start, the UN's more recent 17 Sustainable Development Goals (SDGs) were right up their alley. Their newest product, it would seem, is here to tackle goals #3 (good health and well-being), and #12 (responsible consumption and production). They say these green ingredients are good for the body, and good for the world! We really wanted to learn a little more about the burger itself.

So, What Is the Green Burger?

With this new product on the market, bound to draw eaters of all kinds, including lots of international travelers, the JAPANKURU team knew we had to try some for ourselves, so we got on it asap. The Green Burger is made without any meat or dairy, but according to Mos Burger, the whole point was not to make a vegetarian burger, but to make a burger that anyone, and everyone, can enjoy together! So how is it really?



To start: the base of the Green Burger is a plant-based patty from Mos Burger, designed from the start to be different. No meaty additives, all plants. The patty’s combination of soy bean, Japanese konjac root, and cabbage make for a new take on some classic ingredients, plus some intriguing additions. And this soy-based patty makes no misguided claims at tasting just like meat, but instead has its own satisfyingly savory, umami-filled flavor. Soy patties have been floating around the veggie burger scene for years, and even Mos Burger has already been offering them on their menu, but this plant-based patty makes use of a brand new formula. The Green Burger patty is mildly flavorful, with a gratifying texture that meat-eating members of the JAPANKURU team found appealing, but vegetarian tasters still didn't find off-putting. It doesn't taste like fake meat, it just tastes good!

Surrounding the patty is a bed of crunchy, fresh lettuce, but right on top is the all-important Green Burger sauce. Mos Burger is known for delicious sauces on their burgers (and also known for generous sauce portions!), so we heard that nailing the sauce was an important hurdle that the company had to overcome before releasing the burger to the public. And to make it even harder on themselves, Mos Burger decided the Green Burger (sauce included) needed to be made without "The Five Pungent Roots", called the Gokun (五葷) in Japanese.

The Gokun are onions, garlic, scallions, chives, and leeks, and they’re avoided by people who believe in certain philosophies. Mos Burger wanted to make the Green Burger available to everyone, but of course leaving out garlic and onion (such important flavors in so much vegetarian cooking), made keeping things flavorful a little more difficult. Somehow, though, we think they pulled it off. A hearty tomato sauce with flavorful additions like traditional Japanese gobo (ごぼう, a vegetable also called "burdock root" in English), it adds an important contrast to the simple soy patty.

Of course, the moment you see (or even hear about) the green burger, you have to be curious about what makes it green! Sure, there's the symbolism of "green," using eco-friendly ingredients and processes, but the burger's bun is actually green, as well. In person, it’s a pleasant, pale shade of green, and that’s because the color comes from... (drum roll please)... spinach! Nothing scary about that. It doesn't add too much spinach flavor, just a nice leafy green tint to a simple wheat bun!

Having judged each of the individual sections of the new Green Burger and deemed each of them, well, pretty good, would we order one again? Would the vegetarians in our group want one? Would the meat-eaters bother to go for the soy patty instead of the standard, meaty, reliable Mos Burger?

Unanimously: yes! While each of us have our own Mos Burger favorites, preferences honed by quite a few trips to the burger joint while living in Japan, we all thought the Green Burger was a pretty good choice for anyone, dietary restrictions or no. Ordering a Green Burger definitely isn't sacrificing flavor for peace of mind - it's just another solid option from trusty old Mos Burger. A brand new addition to their menu of tasty burgers!

Our Other Favorites

Well, we might be adding the Green Burger to the rotation, but we did mention that we already have some other Mos Burger favorites, didn't we? The obvious choice for many on the JAPANKURU team is the original Mos Burger. Succulent beef, a thick slice of tomato, and some of the original secret sauce, beef eaters just can't resist the classic.

Diners who like a little history, along with a lot of flavor, might want to go for the beef patty teriyaki burger. This is THE original teriyaki burger, a Mos Burger invention! And imitators still can't compete.

For a little novelty, might we recommend a rice burger? We have to recommend the seafood tempura burger with a rice “bun.” You can really see the ingenuity at Mos Burger - the same creativity that led to the teriyaki burger and the more recent Green Burger - by just looking at these unique burgers surrounded by buns made of rice. Fortunately, it's not just a novelty, the rice bun really works. It's tasty!

One more reminder before you rush out the door to try a Green Burger - don't take it out of the paper wrapper! It's made to keep your hands clean while you dive right into your saucy, delicious meal. To learn the best possible way to eat a Mos Burger... ↓
