In North America, Kit Kats are only available in milk chocolate. But in Japan, Kit Kats are available in milk, dark, and white chocolate. In addition, flavours are plentiful - apple, green tea, chestnut, cookies & cream, brandy & orange, kiwi, orange & chocolate, green bean, caramel, Japanese chestnut, melon, vanilla bean, and green tea with red bean and more...too many to list.
Here's something new, Little Kit Kat. Similar to Maltesers, but fruit flavoured.

If you're lucky enough to be in Richmond, BC, there are several stores that sell Kit Kat from Japan. But you have to be quick. You can also find sellers on
eBay too - see new flavours! Check out the Flickr link below to view more flavours.
This is another reason why I like Japan!
