Abstract
When writing reports and research papers, non-native learners of Japanese often experience difficulty in making proper choices of words to fit the context and stylistic levels of the passage. In this study, we summarize results of questionnaire and interviews survey conducted in August through November of 2006. 40 learners of Japanese with different native languages responded to the questionnaire and interview, detailing their experiences on the proper choice of Japanese adverbs to be used in reports and research papers.
