What companies or families in Japan make Akabeko toys? -

The Wikipedia entry for Akabeko , says that the toys are made by less than a dozen family owned workshops in Japan, and the methods have been passed down for generations. They mention the Igarashi family, but no other. Is there a list somewhere of family companies that make these toys? Does anyone know the names of any of the other companies? Has the production of this toy become more comercial since this statment was made?

I checked internet about Igarashi Folkcraft shop. That shop looks closed. I found some shops make Akabeko toys.
