Both are standard-looking maps, honestly - stem and leaf is so obvious I have problems imagining what other form you'd expect, and I have never seen japanese public transport timetable sign before now. It's just standard over here (Poland, UK).
The format of metro map is actually based on London metro, the only major difference is the amount of lines.
