From a Japanese blog, describing first pic below:

At every shrine sale or antiques show there are many dealers selling obidome, the jeweled ornament worn on the narrow obijime cord as an over belt on a kimono’s wide obi. They are often made with semi-precious stones such as jade, coral, amethyst and others, ivory, enamels and cloisonné, silver and other metals and even Bakelite.

One of the examples seems to be one of those dragon/phoenix disk beads with the slotted holes, another seems to use a pair of oval dragon beads.

Then there's that kanzashi with a cloisonne dragon bead that Nick found, so I suppose that's another non-ojime application.
