Japan is full of special “Limited Edition” products with unusual flavours. Most notable is the incredible variety of Kit-Kat flavours, most appearing and disappearing within a few weeks at most. Flavours seen over the last few years include:
Green Tea Milk
Triple Berry Swirl
Muscat Of Alexandria
Ito-En (mixed vegetables and fruit)
Kinako (Sweet Soybean Flour)
Royal Milk Tea
Many are only sold in particular regions of Japan, and are eagerly snapped up as souvenirs for friends back home by people travelling to those areas.
There are already a large number of Japanese Kit-Kat related articles on the web with photos, including:

or simply Google “Kit Kat Japan”
And the official Kit-Kat site lists the most recent additions to the regional lists.
