About Osaka's

We started our business first and foremost with the hope of sharing the food of Osaka with the world.

Until now, one of the region's most popular dishes, okonomiyaki, had not been getting the international acclaim it deserved.

Okonomiyaki is pictured here, a savory pancake especially famous in Osaka and the Kansai region. Traditional okonomiyaki is shared communally and eaten directly off a griddle. 


While okonomiyaki itself deserves to be more famous in its own right, Osaka's has reinvented the dish into something that could be enjoyed in a more casual manner.

We recommend trying our okonomiyaki Osaka Burgers, which we've spent over half a decade perfecting and are like nothing you have ever tasted.

In addition to our standard Osaka Burger, we offer a gluten-free version with a unique kale-based bun.  

Due to our kitchen capacity and operations, we only serve Osaka Burger on Monday,  Thursday, and Sunday (Not Friday & Saturday)


Koji Tamura first dreamed of bringing the Japanese comfort food and dining experience to the United States in 1972 while studying engineering in Los Angeles. One day, his classmates asked him to serve authentic Japanese food, and he decided to make okonomiyaki, a pancake-like dish from his hometown of Osaka.

It was a huge hit and spurred Koji to come up with a way to introduce Americans to okonomiyaki—a burger. In 2014 Koji and his wife, Mari, tested Osaka’s concept in Kobe, Japan (30 minutes from Osaka), and his Osaka Burgers were an instant success. Koji and Mari knew they could translate the same food and experience abroad, and Boulder, Colorado. was the perfect place to start. In 2017 after retiring from a 42-year career, Koji, Mari, and two chefs from Japan moved to Boulder to open the first Osaka’s. The concept has been welcomed with open arms and written up by publications such as Thrillist, Eater Denver, Westword, 303 Magazine, and more.
