This word is either a synonym or an antonym of yesterday’s word. It, too, refers to a region or portion of land (hence a synonym), but the defining characteristic is social or cultural (as opposed to geological, hence a contrasting antonym).
As an example, the Central Valley of California is probably both jalmēsa and japāŋŋien, being geologically and geographically the same throughout (mostly). But while the State of California could be called japāŋŋien, it is not jalmēsa, as it does not have the same climate, terrain, or geology throughout.
