Hi 👋 I’m still a new stay so someone correct me if I’m wrong resale of the tickets starts usually 3 days before the date and you can check if there’s any resales on Ticket Pia. We all don’t know when the resales will be posted since it’s up to those who decided to sell their tickets. It’s sold instantly so I recommend refreshing the website/app often to see if there are any tickets. Also, tokyo had some extra tickets on the day of the concert so maybe Osaka might have some as well.
