Azumaya is a long-established buckwheat noodle restaurant in Iwate Prefecture that opened in 1907, and they are working to develop Muslim-friendly wankosoba. Normally, Muslims cannot eat wankosoba because the source contains mirin. So, Azumaya has invented source sans mirin, and they even use different pot to cook the special source. It’s said that 15 bowls of wankosoba equal 1 portion of normal soba noodle. And, if you can down more than 100 bowls, you’re awarded with their original certificate. Please enjoy Iwate Prefecture’s wankosoba in memory of your trip to Tohoku. Note: Please make a reservation three days before by phone call if you want to order halal wankosoba.
