During the festival, found objects are brought back to the Info Desk (set in hall 6), which keeps them until the end of the festival. We also keep everything found at the festival after its closure, to allow you to get them back.
You just have to send us an e-mail with a precise description of the object you have lost, so that we can identify it. Then we'll get back to you. Send your e-mail to the following address: objets-perdus[@]japan-expo.com.
