Welcome to Japan Forums!
http://hyperdia.com/ has all the train and subways schedules for the country. Do a search for your travel day, then click Interval Timetable under the name of the train to see all trains for that day. Looks like every hour on the hour (7:00, 8:00. through16:00) then 17:40, 18:40, 19:40, but check for your travel day.
You can also use https://www.google.com/maps to search (in English) and get driections.Edited: 03 August 2018, 20:41
