In principle, you are supposed to visit the Japanese customs office in the departure area of the airport before leaving (there is no systematic customs check for departing passengers in Japan), and they will just collect the receipts. There is currently no penalty for not doing so, however, so if you have already left, you can just throw them away.
You can remove it and throw it away. It is for use when leaving Japan, in case Japanese Customs want to check the goods against the receipt. They rarely, if ever, do.
