It is an urgent task for Japan to conduct dynamic surveys on foreigners visiting the country and help make their stay more comfortable at a time when it is attempting to establish itself as an attractive tourist destination and make tourism one of its thriving industries. Our laboratory analyzes reviews posted by foreign tourists about their trips to Japan and researches effective ways to create multilingual websites and promote tourism destinations to foreigners. Moreover, we are developing a tourism promotion system that uses language information and bicycles to inform as many as foreigners as possible about the attractions of tourist destinations across the country.
