Japanese dairy farmers are also being squeezed by high food prices, or at least the Japanese government thinks so. According to this article, the 187.1 billion yen in supports for dairy farmers and stockbreeders, which was already up 63.2 billion yen from last year is going to be raised an additional 70 billion yen. These are mostly in the form of unit-subsidies.
I feel sure the butter shortage has also influenced this move, although any boosts in production will lag far behind a stimulus - especially in the dairy industry, where you cannot exactly plant more cows next year, you have to breed more herds of dairy cattle to make a difference.
