To be frank, Im very worried about food radiation pollution problem since fukushima daiichi nuclear disaster, so these years I always pay special attention on the origin of food my family eat every day. So National Denen is a perfect place for grocery shopping; they have various kinds of vegetables, meat, and dairy product from southern or western Japan. Not to mention National supermarkets’ motto: gathering good things from around the world. So not only Japan Southern or Western safe food, you can also find overseas safe food here as well. Btw, I personally feel National Denen has more kinds of southern Japanese fresh or organic grocery than National Azabu does. They also sell some Costco brand Kirkland products in small packages too, like paper towel, toilet paper, sometimes also Costco food like muffins, which is very convenient since costco is far.
