japontina
Could you specify which sense of the term "japontina" you want the article to cover? The word is not widely established with a single, clear meaning in major reference sources and may refer to different things such as a demonym, a place, a surname, a product or dish, or something else. If you don’t have a particular sense in mind, I can draft a brief, neutral disambiguation-style article that outlines the possible meanings and notes the lack of a single, widely recognized definition.
