15% off Japan Activities (Including JR Pass) @ Klook (Stack with 10% Cashback @ ShopBack)
Have just found a cracker deal for those looking for JR passes. I've tested the promo code on a JR pass and it works. Factor in the 10% cashback from Shopback for further savings!
Klook is also doing 15% off theme parks - use promo code CFKLKPARKS.
