AFM Furniture-Japanese modern rocking chair-ID help  

I bought this rocker a few weeks ago, and am trying to find out any information about its manufacture. It has a plate on the underside which reads "AFM Furniture Made in Japan". I was told it was designed by a contemporary of Noguchi, but the dealer couldn't remember his name.

Something not apparent from the photos: it's got the kind of leg joints where screw heads on one side fit into a drilled metal plate on the other. Any help would be much appreciated.

More images of the chair are at the flickr link below:
