Kitayamazaki coast access

I'm planning to go to Kitayamazaki in early May on the way from Sapporo to Tokyo and I have some questions about getting there:

(1) I'm finding conflicting info about buses from Tanohata station to Kitayamazaki. One site (http://wikitravel.org/en/Tanohata) says there is no bus service Saturday and Sunday, but the JNTO website says there is service on Saturdays. Which is correct?

(2) Is it possible to get to Kitayamazaki from another station besides Tanohata where the buses would be more frequent? Fudai station seems to be nearby but I can't any info on buses from it.

(3) Can I rent a bike somewhere in Tanohata (or another station nearby) to bike to the coast?

(4) How far would it be to walk from Tanohata or Fudai station to the coast? Or take the bus there and walk back? Would it be a scenic walk?

Also, (5) are there are nice hikes around Kitayamazaki observatory to take in the coast?

Any advice would be greatly appreciated. Thanks!

I think the most reliable source should be that from Kinayamazaki Visitor Center.
