Despite the recent completion of the Expo, organizers have announced they plan to continue sales of popular Expo-related merchandise. This initiative aims to extend the influence of the event and cater to the high demand from citizens who wish to own keepsakes commemorating the experience. Detailed info on the items available for sale, and the platforms on which they will be sold, will be forthcoming.

In Japan, the sale of items associated with memorable events often extends beyond the closing date. Japanese people cherish souvenirs as reminders of their enjoyment, and sellers see these sales as an economic opportunity to continue capitalizing on an event's popularity.

In the US or EU, expo or event merchandise is also often sold beyond the date of closure, especially if the event was particularly popular or significant. These items offer an extra revenue generation point and provide fans a memento of their experiences.
