This post has been updated as a brand of greek yogurt is available in many stores.Amazon.
The above yogurt is Caspian Sea yogurt (kaspikai youguruto カスピ海ヨーグルト). It is not thick like Greek yogurt but is thinner. It is smooth and rich. I’ve seen it in most supermarkets that stock at least a few foreign products.
If you can’t find Greek yogurt in your area you can always strain regular yogurt. Here are some instructions.
