The purpose of this study is to find the characteristics on structural complication in compositions written by advanced Japanese learners (non-native speaker: NNS) compared with those of Japanese native speakers (JNS). The data was obtained by assigning a research essay to 32 Chinese speaking NNS and 30 JNS. The results were: 1. NNS used many more adverbial clauses, especially more conditional clauses and concessive clauses marked by "keredomo" than JNS. JNS used more final clauses. 2. JNS used more adjective clauses. Antecedents of NNS's adjective clause were limited to subject and complement.
