Very useful if you can get an English language train timetable. I went to Japan a long time ago.
Sometimes on the train, I was not sure where I was - the station names were in Kanji.
However, if the timetable says a train will be somewhere at 10:37am and that is the time - then that is where you are.
In Japan, a train that is 1 minute late - is seriously late.
Once at Tokyo station, I went to Platform 4 to get a bullet train to Hiroshima at 08:04am.
At 08:00am, sure enough, there was a bullet train arriving at Platform 4.
That was NOT my train.
That train left and my train arrived at 08:04am.
