Chef Masaharu Morimoto, known as one of the original Iron Chefs, takes on the role of judge and mentor in his new sushi competition show "Morimoto's Sushi Master.” Presented exclusively on the Roku Channel and spanning six episodes, the series — hosted by Lyrica Okano from Marvel's "Runaways" — will feature eight talented chefs from across the nation. With a cash prize of $25,000 at stake, the contestants will be evaluated not only by Morimoto, but also by judges such as award-winning cookbook author and content creator Kenji López-Alt and chef Dakota Weiss.
