It appears the people in this picture are all part of the same family. In the picture you can see three generations of the family working together on the harvest.
The four women are engaged in various tasks. The woman on the farthest left is grinding something within her bowl, while the woman to her right is dicing a radish. The two women on the right are tending a fire.
The men here are depicted in full Kendo gear. Their armor and swords are designed to be used in practice against one another without causing harm. However, the mat/stage upon which the main subject of the picture stands could not serve as a ground to hold a Kendo match, as it is much too small.
