Don't forget to produce your passport when purchasing at Mandarake (and a lot of other department stores) to get duty-free prices.![]()
If you or anyone else happens to be in Osaka and you happen to speak Japanese or be with a friend who can speak Japanese, try Hero Gangu and haggle with the management. You can score an additional discount on top of tax-exemption with the presentation of your passport - yeah, they actually stack discounts there.Do not try this anywhere else though, as haggling is generally considered offensive in Japan.
