When creating an event that takes place in Japan and setting up a ticket link type to Presale, that link automatically becomes the Preferred ticket link so it remains on top when the On-Sale begins.
 
Any ticket links you add will also be included in the links listed, plus any links imported by Bandsintown. You can select any of these ticket links as the Preferred ticket link by clicking on the circle button next to the link you prefer. You can also edit the event and change your selection at any time.
