As there has been a significant increase in foreign visitors to Japan in the last few years, there is an increased need to establish multilingual fare charts and signs at railway stations and near ticket vending machines. This study focused on fare chart visibility and the possibility of downsizing fare charts to make space for multilingual charts. The elevation angle, viewing distance, text size, and chart luminance influenced fare chart visibility. The elevation angle affected how close a customer can make an approach to read the fare chart. The viewing distance, text size, and chart luminance also influenced fare chart visibility. Using multiple regression analyses, an estimated formula with high fitness (the adjusted R-square was 0.80) was determined.
