MOS Burger (モスバーガ) is a popular Japanese fast food chain that originated in Japan. MOS stands for Mountain Ocean Sun. MOS Burger is famous for their original burger, which is called the MOS Burger.

They are also famous for their unique burgers such as the MOS Rice Burger, which they have been serving now for many years. The rice burgers use a bun made of rice mixed with barley and millet. Last month on April 23rd they launched their new Tempura Rice Burgers, which will be available for a limited time (until the end of October). These are more than your typical burger as the tempura is sandwiched between grilled rice which acts as the buns and hence the name “rice burger”.

The two new Tempura Rice Burgers are:

Ebi Shinjo ~ Fried Shrimp Dumpling Tempura Rice Burger

The fried shrimp dumpling contains grated shrimp and onions, which are fried in tempura batter and then topped with a Japanese style sauce that contains oroshi (grated daikon), with added ao negi (green onions) on top. This is all sandwiched between two plates of grilled rice. The Ebi Shinjo costs 350 yen (USD$3.60)

Kisetsu no Yasai Kakiage ~ Seasonal Mixed Vegetable Tempura Rice Burger

The tempura in this burger contains various vegetables such as onions, edamame beans, and sweet corn. This is all fried together in crispy tempura batter and topped with an original wasabi and seaweed sauce. The tempura again is all sandwiched between two plates of grilled rice.The Kisetsu no Yasai Kakiage costs 280 yen (USD$2.85)

How Do They Taste?

We tried the two new rice burgers and give them both the thumbs up. The rice bun is very much like a yaki onigiri and the fillings were tasty and reminded us of Japanese dishes like Ten-don (tempura on rice) and Kakiage-don (mixed vegetable tempura on rice). We would definitely have these again.
