Butter Shortages
I had some time to check out the situation yesterday and found that margarine has almost entirely replaced butter on the shelves of two high-end supermarkets near my office: National Azabu and Meidi-ya. What they did have was predominantly imported and they both had signs describing their policy of one package of butter per customer. Naturally the prices were higher than usual as well.
After being used to American and Japanese abundances, this was pretty shocking. Apparently increased costs for dairy food stocks as well as higher demand for dairy products is to blame.
