Hehe - how true! The sister in one of the families I lived with LOVED it. She always had some in the fridge but the darn container wouldn't stay closed once you took the plastic off of it. It made the whole fridge reek of natto. You could always tell who had been in the fridge last - Yurika if the natto was open (because she had eaten a little) or me if there was something sitting on top of the natto container to keep it closed!
