This study forms part of an attempt to develop an "online email text correction system". From the result of Kim, Hashimoto, and Kaneniwa (2015), this study made ten new simple email tasks using a limited vocabulary and then analyzed how ten native Japanese speakers and ten Korean learners of Japanese used the required words. The members of both groups used almost exactly the same number of required words for each task with a few exceptions. The result therefore showed that these new tasks can be used to help evaluate the new correction system.
