彼処

From Old Japanese. Appears to be a compound of 彼 (a, “that one over there”, distal marker, indicating something distant from both speaker and listener) +‎ し (shi, possibly the directional marker found in terms such as 昔 (mukashi, “ancient times”), 縦し (tatashi, “the standing or vertical direction”), 横し (yokoshi, “the sideways or horizontal direction”)) +‎ 処 (ko, “place”). May be the older form of modern asoko below.[1]

Appears to be a compound of 彼 (a, “that one over there”, distal marker, indicating something distant from both speaker and listener) +‎ 処 (ko, “place”).[1][2] First appears in the late 1500s, early 1600s,[2] and used mostly in the Kansai region.[2][3] Given the historical tendency for innovation in the Kansai region, the term may instead derive as an abbreviation of asoko above, by analogy with the -ko suffix in ここ (koko, “here”) and そこ (soko, “there”, closer to the listener than to the speaker).
