KitKats with a kick. Japaese KitKats, in their most infamously bizarre flavours, are now available to buy from japancentre.com. This box of 12 mini Wasabi KitKats is normally only available to buy in Shizuoka; an area of the country well-known for its wasabi production. Light green in colour and made with real wasabi, this must-try chocolate comes with a subtle and sinus-clearing fire that is sure to delight wasabi lovers.
