Kura Sushi, Inc. is a Japanese sushi restaurant chain. It is the second largest sushi restaurant chain in Japan, behind Sushiro and ahead of Hama Sushi. Its headquarters are in Sakai, Osaka Prefecture. It has 543 locations in Japan, 56 in Taiwan, and 61 in the United States. While it is a conveyor belt sushi chain, it relies on a high level of automation allowing the average location to function with fifteen to twenty staff members. At Kura Sushi's locations, a robot known as "KuraB the Kurabot" delivers foods, beverages, and other objects, however sometimes employees will simply supply the beverages themselves. Wikipedia
