Weekend train schedules Japan

Heya.
Since not used to Japanese train and bus timetables I have been looking at Hyperdia to see how often some trains and buses run on different days, including weekdays. Where I live the trains and buses run less frequently on weekends and holidays but not sure if it is the same in Japan since the timetable look the same on for instance wednesdays and sundays.

Are there no less frequent trains during weekends in Japan? What about national holidays like golden week and New Years eve? Are there any list of Japanese holidays so I know when trains might not run like they do on regular days?

Thanks!

Jo,

Apart from the fact that there are no morning or evening rush hours, the train timetables are generally much the same at weekends (and on national holidays) as during the week. Unlike in some countries, the railway companies understand that many people wish to travel by train at weekends, and even more trains may be run at busy periods like Golden Week or New Year.
