To support the ability of self-directed reading, it is necessary to do not only classroom activities but also reading activities outside of the classroom. Especially abroad, where there is minimal access to Japanese, supporting and cultivating self-directed reading could become a problem. In this article, I will report on and analyze the effectiveness of the reading activities "Reading Diary" and making a "POP". These activities were held in a training program for teachers of Japanese from abroad. As a result, these activities increased their motivation to read as well as broadened the variety in their choice of reading material. In addition to that, some of them said that they would like to try these activities in their classroom.
