hunter/gather requires little effort and large populations can be
supported. One book that I read suggested this for the reason why the
Japanese were so late in taking up agriculture. There was no need to do
all that hard work. As pointed out, it's possible that rice was raised
as a special item for the nobility before it's common introduction.
