The breakthrough of information technology has accelerated the evolutionary change in teaching and learning methodologies. In particular, pervasion of high-efficiency smartphones has raised the potential to generate a new learning environment called seamless learning, which has been drawing much attetions from researchers in pedagogy of any domains. However, career education using information technology is still in the stage of emergence. There are some reports on ICT implementation to career education such as portal sites for students' career support, the use of ePortfolio in career education, e-Learning in career development for university students and e-mentoring for career development. But no such learning system using seamless mobile learning technologies to enhance career education for international students has been developed yet. The Japanese government, in 2016, declared "Japan Revitalization Strategy 2016". It includes the increasing of the number of foreign workers who gain employment in Japan after graduation. They set the goal from 30% to 50% of the international job hunting students find jobs in Japan. Therefore, career education for international students has become an urgent issue to tackle with in Japan. In fact, many universities in Japan have started providing international students with career education such as business Japanese, business communication and career design. Since Japanese job hunting process is very unique, most foreign students have anxieties about it. According to the survey conducted by the authors, the top two anxieties that international students had about job hunting in Japan were (1) language-related anxieties: writing CVs and entry sheets (writing skill) and job interviews (listening and speaking skills) and (2) an anxiety about how to get information to find a job. There are many terms used in job-hunting processes, which are so rarely used in daily conversation that even advanced learners of Japanese are yet to learn. The survey result also showed that more than half of the questionees selected "I don't know how to get information". It means that it is very important to convey necessary and useful information to international students who are eager to find jobs in Japan. The objective of this study is to propose an effective career support system to get rid of the above-mentioned two anxieties. Our ultimate goal is to contribute to the enhancement of their employment rate in Japan.
