Such issues are not a problem with Oreos in Japan. Not only are they limited in the scope of their releases, but the size of any given offering is quite small. This green tea chocolate Oreo snack has only eight 5.9 gram (.2 oz.) pieces. They are two small bites and only 32 calories each. This makes them close to the Oreo equivalent of a Hershey's Kiss in terms of overall size. So, this stuff isn't likely to be lying around for 5 months. Well, it might if it really sucks.
The beauty of mixing green tea with something like an Oreo cookie is that it is where sweet meets bitter. The odd thing is that most of the sweetness is coming from the green tea chocolate that is binding fractured bits of bitter chocolate Oreo cookies together. While I have not been the greatest fan of green tea sweets in the past, they have really started to grow on me and this one hit all of the right spots.
The smell when you open the package comes mostly from the green tea. The flavor is a very good mix of both the chocolate and the tea with the tea dominating at first and the cocoa flavor coming second. It's nice that such a tiny bite has a couple of flavor notes rather than lacking depth. The other thing which really hits me the right way is the textural contrast between the soft green tea chocolate and the crispy cookies. It's satisfyingly crunchy without being brittle or too hard.
If you hate green tea, you probably will not be a fan of this. It's definitely strong enough on the tea meter to put off anyone who isn't a fan. If you are a fan though, this is really good and worth a try. I got this courtesy of the fine folks at Candy-san. They are currently selling it for 210 yen, which is probably only about 50 yen more than it retails for in Japan and less than I'd have to pay for it in a Japanese market here. If you don't like them, at least your pet pig won't get fat if you feed him the leftovers.
