This study reviews request behaviour and territory in terms of (1) existence of words (2) discourse structure (3) Predicate Expressions between Japanese, Korean, Korean Japanese Learners. It results in as follows; (1) In Korea, it is acceptable to use a pen of a close friend without any consent, which describes that one does not consider the other`s property or territory. (2) In terms of Discourse Structure, both Korean and Japanese use a short dialogue stating the key point. However, Japanese language contains expressions of excuse or sorry, which shows the property or territory of the other`s. (3) Unlike Korean or Korean Japanese Learners, Japanese usually use the expression of ~ga~ni kariru, kasu, miseru. They are called ``Three Arguments Verb,`` which states ``proprietary relations,`` and take the other`s property or territory into account. (4) Intermediate Japanese Learners usually communicate their ideas using the expression of Two Arguments Verb such as ``tsukau,`` ``miru.`` When one requests to show materials, he or she uses ``miyou.`` It is, based on the Korean Mother Tongue, represented in Japan Language expressions, which also features for Inter Language Learners. This study will contribute to increase mutual understanding between Korea and Japan, and it will be useful to teach Japanese to Koreans or vice versa.
