I have been to Japan twice during this time and, as a tourist, didn't really notice any of this. Is this why seemingly all the butter in Japans restaurants is imported from Australia?
The current butter crises is not as bad as the previous ones. While my local grocery store regularly has a sign saying "butter sold out nationwide" the 7-11 down the street seems to have some and the bakery next door is using a lot of butter in their products.
