Nintendo is going to open a Switch Golden Week 2019 SALE OFF event from April 25th to May 8th in Japan. This event applies for both Nintendo Store and eShop, offering various sale off rates range from 20% to 50%. The list of all of sale off targets can be referred here ¹, but it might also be noted that two remarkable Switch exclusive titles including Mario Odyssey and Mario Kart 8 Deluxe would be getting 30% OFF (
¥6,458 → ¥4,520) during the event. In addition, Mario Odyssey just received a free VR update recently (according to Nintendo, all new contents in this update are playable without VR, but VR will enhance the vision to 360°), so this offer is very worthy for Mario fans who already had or are going to get Nintendo Labo Toy-Con 04: VR Kit ² but not own the title yet.
1) The currency used by Japanese Nintendo Store and eShop is Japanese Yen, hence purchase with other currencies will lead to currency exchange fee charge
2) Japanese Nintendo Store supports only domestic shipping (JP)
3) Japanese Nintendo eShop doesn’t have region restriction, so any customer can easily purchase games directly from there as long as owns a Nintendo account had the country set to Japan
