Hi - the Kansai Wide Pass allows my entry into Shikuko, Utazu Station. However, my destination from Kinosakionsen via Okayama to Oboke Station. How do I purchase the ticket from Utazu Station to Oboke Station? Can I pay for it when I arrive at Oboke Station? The Ltd Express train Nanpu is a direct train from Okayama to Oboke Station and I only have 15 mins to change platform at Okayama. Thank you!
