The group above must have participated in a festival or celebration of some kind. The people in the group are wearing a variety of different outfits. The photo came from an estate in Texas, with no information about where it was taken or when. The back is blank. [Note: this post has been updated with location information provided by a reader. See the end of the post for details.]
At the center of the group is a young child. In the back, a man and woman are wearing medical masks! I’d guess the masks were part of their costumes, since no one else is wearing them:
I’ve divided the photo into two parts, which you can see below and in higher resolution in the image gallery which follows:

Update #1: Fellow blogger Shayne Davidson asked her son Adam, who lives in Japan, if he could read the writing on the lapels of the women at the front of the group. He very kindly did! He wrote, in part:
The coats have “Hanamaki” written on them, and the little girl’s coat has a river name written on it that appears to be an actual river in Hanamaki in Iwate [Prefecture]. […]
It looks like a festival, but I don’t see any clear indication of which one exactly. Looking at the photos again, several of the adults have “fire brigade” or “civil defense brigade” written on their lapels. When I lived in Ninohe [also in Iwate], the local volunteer fire brigade always marched in the summer festival, so this looks to me like a group posing before or after such a parade. […] It’s particularly interesting that the fire brigade and civil defense brigade people are all women.

A big thank-you to Shayne and Adam for this very helpful information!
