This document discusses a system called Asia Trend Map that forecasts the popularity of Japanese content such as anime, manga, and games in Asian countries over the next 6 months. The system collects data on these cultural products from Twitter, Wikipedia, and search engines in different Asian languages and uses this web data along with past Japanese sales data to train a model that can predict future trends. The results showed the system could improve its predictive accuracy by combining data sources and that Wikipedia data, especially page content attributes, was particularly helpful for predicting longer term trends.
