Recently, a lot of people often visit foreign countries due to the progress of globalization in the world, and Japan also aims to become a tourism oriented nation. However, various languages are used in the world, and it has become a bottleneck for the people to visit other countries. In this research, by combining the smartphone and the digital signage based on iBeacon technology, multilingual information service system was developed. This system was implemented into the information service in Shirakawa-go that is one of the UNESCO world heritage site, and the evaluation experiment was conducted. In the experiment, several foreign tourists were asked to use the multilingual information service system and the effectiveness of this system was evaluated.
