Ringer Hut is a Japanese chain of fast-food restaurants, specializing in Nagasaki dishes Champon and Sara udon. The Hamakatsu Co. of Nagasaki, founders of the chain in 1974, borrowed the name of the former Ringer House which had been purchased by Nagasaki City and opened as a tourist attraction in 1966. It is likely that the company borrowed the word "hut" from "Pizza Hut." In 2009 Ringer Hut operated over 550 restaurants in Japan and Taiwan, along with 100 Hamakatsu Restaurants. Ringer Hut has two headquarters located in Fukuoka and Tokyo. Wikipedia
