Japan's news broadcasts have been HD for years. Congrats on finally starting to catch up.

The trial runs only two weeks, starting March 27, and the sake will be available only in one store. Note that two different kinds of RFID tags are being used. One has a built-in temperature sensor and is rather large (attached to the carton), the other is a thin label on each bottle that stores an ID. The ID is used in retrieving information from a data center about the sake. Another key part of the system is a portable cool box, which gets its power from the hybrid system of the truck, and which can be unloaded with the sake still inside.

This kind of special care isn't necessary with most sake, which is pasteurized, but only with namazake, or unpasteurized sake, which has a fresh, zingy complex set of flavors not found in the ordinary stuff.
