From 1st October 2014, three times a day.
Maybe you think this is not a big difference but for small town, this is a big change! :)
By this change, you can travel to Miyazu or Amanohashidate from Kyoto after you finished sightseeing in Kyoto because the last bus leaves at 18:00 from Kyoto station.
Although, local buses in Tango region is already finished by the time when you are arriving in the area, make sure you already have place to stay and you need to take a taxi or book pick up service or stay at walking distance from station.
