Food supply

One thing people might be wondering, is how we are going to feed these people?  One thing is that if the Suzume lands could be increased in fertility by using adding organic matter, they might be able to be more productive.  I think using Japanese Organic Agriculture could improve the fertility of the soil.

Another thing is that, other lands may be more productive then the Suzume's.  Where the Suzume's may teach their Kenjutsu to the other families.  This way it will give them another source of income besides farming.  Then the other families can perhaps could give the Suzume produce for their lessons.  I know teachers in Okinawa got vegetables.

Also perhaps if the Sparrow could pursue aquaculture, then that would also aid in the food production.  As this would be another source of food.  It would be best to have multiple food sources.  As if one should fail then atleast there would be another.
