うどん (udon) noodle shop sign in Kiyomizu, Kyōto, Japan. ☆Actually, it reads おめん (omen), which sounds unfamiliar even for the native Japanese in general. It&#x27;s been said that おめん (omen) is a dialect for &#x27;udon&#x27; in part of Gunma, where udon originally came from, and since it wasn&#x27;t acknowledged in the Kansai region at the time, they decided to make their trade mark the same with the menu name so as to widely spread it. おめんは群馬県一部地域の方言がなまったうどんの事。うどんにまだ馴染みが無かった関西に持ち込んだ際、解りやすくする為に屋号とメニュー名を統一。★京都、清水。
