Simple and convenient, and slightly cheaper than the official website; just take the QR code to the ticket machine to get your pass, and then reserve your seat. The ticket machines at Kansai Airport only accept tickets for the same day; otherwise, you'll need to go to the green window or another station to reserve a ticket for a specific date, especially on evening trips back to Osaka when they might be full. This is the best recommendation for those wanting to visit Tottori and Shimane.
