Japanese micro-soup

This Christmas I received some tiny soup packets from Japan as part of a gift. We have instant soups worldwide, of course. But these ones take the form of 'rusks'. And they're much tastier than the average chemical concoction you get in packet soups. More like freeze-dried real soups, actually. Perhaps that's what they are? (My Japanese reading isn't yet good enough to work it out!) Worth a try, though.
