This is very popular item for tourists visiting Japan.
My friends of Philippine and Singapore also like its flavor of Chocolates or Cookies.
I like Maccha ice cream like Haagen-Dazs.
When I have chance to visit Japanese cha-ya(茶屋) /tea house, I like to try real Maccha drink.
Also, as you know there are maccha flavor latte and Frappuccino in Starbucks.
＊Maccha is made from one of the green tea leaf called Tencha(碾茶) (not 甜茶)
If you want to get this Kitkat in Japan, go to Local supermarket!! They offer it with local price. Cheap!!
