The changes will require visitors to pay the full price for goods--including the consumption tax—at the duty-free shops, and these purchases will be recorded electronically in their passports. Upon departure at airports or seaports in Japan, the passports will be scanned to confirm the purchases, and customs officials will refund the consumption tax to the departing travelers. Since opening the suitcases of every tax-free shopper is impractical, customs officials will only inspect luggage for purchases that exceed a certain amount, which will be determined later, the sources said. Currently, tourists are not charged the consumption tax on purchases at duty-free shops. If they want to resell the goods, they must pay the 10-percent tax.
