To achieve the goal of this study, participant observation and interview were performed in order to examine the changes in awareness through overseas off-season training of soccer players at E high school for four months from December 2013. As the result, the followings were found. First, the soccer players at E high school had positive and negative perspectives and evaluation on overseas off-season training due to sudden change of environment. Second, there was self-reflection by overseas off-season training. High school soccer players had realized indolence and lack of challenging spirits, and they have made resolution and new determination to solve from such issues. Lastly, the team has built up community spirit through overseas off-season training. The overseas off-season training in Laos was new stimulant and opportunity for the soccer players at E high school to experience changes in perspective.
