Tokyo’s Square Burger claims it’s a viral hit with foreign tourists who’ve given it near-perfect Google reviews

Burger stand near Tokyo’s most famous temple has local partners with more than 100 years of history helping the Square Burger stick out from the crowd .

They say nobody’s perfect, but with an average out to 4.9 out of 5 stars as of this month for Kadomasu-The Square Burger, the Tokyo restaurant’s Google user reviews say the place is about as close to perfection as you can get .

This isn’t a case of the restaurant lucking out with a string of its earliest customers all coincidentally happening to like the place before a larger sample pool pulls ratings down, either, as those 4.9 stars are the average from across more than 2,000 customer reviews.

As you can probably guess from its name, the star of the menu at Kadomasu-The Square Burger is the Square Burger .

To illustrate just how proud they are of the sandwich, the restaurant used to just be called Kadomasu, but since the Square Burger was added to the menu last spring, the management says that it’s been generating a huge amount of positive buzz on social media among foreign tourists traveling in Tokyo .

Kadomasu-The Square Burger also says that over 80 percent of their customers are visitors from overseas .

Kadomasu (which also serves steak skewers, desserts, and drinks) is located in Tokyo’s Asakusa neighborhood, not far from the famous Sensoji Temple .

For its patties, it uses A5-grade wagyu beef, but why are its burgers square? There’s at least a little wordplay involved — the “kado” part of Kadomasu is the Japanese word for “corner.” Being square, though, also lets the patties match the shape of the bread that’s used for the burgers.

Yes, that’s right, bread, not buns.

As an Asakusa restaurant, Kadomasu wants to make a uniquely Asakusa burger, and they say they get their bread from local bakery Terasawa, which was founded in the neighborhood in 1950 .

The Square Burger’s bread is specially made for the sandwich, with golden sesame seeds kneaded into it for a nutty accent, and toasted on the restaurant’s flat grill with a generous amount of butter, cooked to achieve a crispness on its outer surface but a soft fluffiness closer to its center.

Said bread is delivered to the restaurant, freshly baked, every morning, personally by Terasawa’s third-generation owner, Masahiko Terasawa, according to the management.

The partner for Kadomasu’s burger sauce has an even longer history.

Sauce maker Tokiha Sauce has been part of the Asakusa neighborhood since 1923 , and after a few extra ingredients are added to Tokiha’s vegetable-based Nama Sauce, it becomes the spread for Kadomasu’s Square Burger.
