Tamashii Ramen House opened June 1st, 2015. It was founded by Matthew and Wakana Sebacher. The restaurant was conceived when Matthew and Wakana noticed a need for this type of cuisine in Oklahoma. They wanted to introduce authentic Japanese Ramen to Oklahomans and share their experiences with Japanese cuisine. Since the idea of conception arose, they have opened three restaurants at Midtown, OK, Edmond, OK, and Norman, OK.
