In terms of timetables for Japanese rails, just download Jorudan. Its in Japanese, but even someone with no skill at the language can figure out how to work it in 5 minutes.
I wanted Hyperdia because it offers a range of several train times at a search, but thats the only leg up it has. Jorudan is labeled as free, IS free and will get you where youre going. This app needs to be relabeled as a trial. Disappointing.
