When someone asked me what kind of souvenir I would recommend from Japan, the first thing that came into my mind would be Japanese KitKat. KitKat is a product from Nestle, which is not a Japanese company, and yet the flavors of these KitKat chocolates from Japan were unique and different from Kitkat from other countries and some were somehow “bizarre” making people curious and want to try them. Japanese KitKat has a wide range of flavors, some of them are produced and sold in limited time, some of them are sold only in specific region as some kind of specialty souvenir from the region. They even have a KitKat flavor map in their website.
Japanese KitKat has obtained popularity, some of them could now be found quite easily like these green tea KitKat and black biscuit KitKat which could be found in several supermarkets in Jakarta. These two KitKat packages have オトナの甘さ written on it. Does that mean “adult sweetness” which means that they are not very sweet?
When I was living in Japan, I bought and tried several flavors of KitKat whenever I could get a hand on them.
