I can't read japanese, but someone in a japanese grocery said that it is japanese yogurt powder. My Mom loves this and can't find the box that it came in, nor can she remember which friend gave it to her, but has this last package which I have attached. We have scoured many of the japanese groceries looking for this item to no avail. We even went to the large japanese mall, Mitsuwa Mall in Edgewater, NJ and turned up empty. Any help or suggestions would be greatly appreciated.
