What’s Okinawa Soba? Okinawa Soba is a regional dish from Okinawa, Japan. While soba is usually known to be buckwheat noodles, the noodles in the Okinawa soba are flat noodles. The light bonito and kelp broth taste great with the flat noodles! To recreate this dish, we used our Okinawa Soba. To fully experience the taste of Okinawa, make sure to add in some thick cut stewed pork belly! The bigger the pork, the better!
