When I was riding on the train bound for Saidaiji, I asked my colleague whether he can ensure a seat on his way to school.
He replied that he takes the express train departs at Takanohara in order to ensure a seat.
Express trains on Kintetsu Kyoto Line usually terminate at Kashiharajingu-mae, Tenri ,or Kintetsu Nara.So, I was surprised to know it.
But, he has not yet found the way to ensure a seat on Keihan Main Line.
