Apparently, you can find anything in a vending machine in Japan.  I found this small tent with a refrigerated vending machine. Each small compartment contained a bag of eggs, probably 10 or 12.  The cost was 300 yen, or about $3. The eggs are from a nearby farm, and the farmer fills the machine daily with freshly laid eggs.  I will need to buy some and see how they taste.
