Thin sections for the microscopic observation were made of human remains from five Jomon sites; Miyakojima, Ebishima, Ubayama, Ikawazu and Yosekura. These sites except Yosekura which is a cave site of limestone, are shell mounds. The bone pieces considered as a part of long bone were embedded in Metacrylate and Polyester, and were sliced about 500μ thick and ground off 100μ thick or thinner. Some of these sections were stained by Hematoxylin and Eosin. Bone tissues of these samples are destroyed greatly. The best preserved samples are from Ubayama, but their lamellar structures are destroyed. On the samples from Ikawazu, only traces of Haversian or Volkmann's canals can be found and even the polarization microscope scarcely shows collagen fibers. Burned bone from Yosekura has better preserved lamellar structures than the unburned one, but collagen fiber is not well preserved.
