These special edition Kinoko no Yama and Takenoko no Sato boxes really aren't a good deal. I don't know how much they cost in Japan, but in the United States, they are usually one of the pricier snacks in Japanese grocers, often over $3 a box.
For that price, there really isn't that much inside. This package might have had 6 or 7 individually wrapped pieces. That's probably good for portion control, but it's beginning to get to me in terms of value.
It had a potent strawberry smell with a hint of cheesiness. There were actual strawberry seeds embedded in the chocolate, and the strawberry flavor was pretty authentic. The cheese taste was subtle, a little yogurty, but recognizable.
The cookie/chocolate balance in the larger size held up better than the Takenoko no Sato that I tried recently, but the chocolate did feel a bit overwhelming and sweet on the finish. In general, though, I'd say these were better than the average strawberry cookie snack.
