Vintage bisque? Germany and made in Japan dolls

Any idea of some history on these. The 12 babies in the pink blanket are bisque I believe. They say Germany on the neck and what looks like a 7/2 or 712 on their back. There are 9 with blue ribbon and 3 with pink ribbon. The arms and legs move and are connected with wire. The twins in the blue and pink blanket are made the same but the arms and legs are held in with a thin rope. They say Made in Japan and have a mark of some kind on the back. The single one in the frilly bunting is made with the thin rope holding the arms and legs on and says Japan.
