Japanese Kit Kat & Tirol
The idea of putting KitKat on this list may seem strange to British natives, especially as the confection was actually invented in the UK, but I have a very good reason for doing so. If you buy a KitKat in the UK, you can usually expect the classic flavours: milk chocolate, dark chocolate and white chocolate.
However, in Japan, they have taken the humble KitKat and turned it into a confection that takes on just about any flavour you can think of.
Prefectures create special local flavours for KitKats, seasonal flavours are often on rotation and you can find a multitude of exciting flavours in souvenir shops all over the country. Such flavours include sake, yuzu, Kobe pudding, matcha, sweet potato and so many more.
