Osaka Expo Signature Pavilion EARTH MART This is a set of two exchange tickets for "Banpaku-zuke" pickled plums, actually pickled within the pavilion. The "Banpaku-zuke" will be stored for 25 years and can be tasted in 2050, and these are the exchange tickets for that event. Details such as the date, time, and location of the exchange event will be announced on the Kishu Ume no Kai (Kishu Plum Association) website shortly before the event.
