During the 13th and 14th centuries, the water in the lower Amur basin began to freeze. This climatic event lasted from the eighth month of the lunar calendar until the fourth or fifth month of the following year when thawing began. Such records are found in the Chinese historical sources of the 13th and 14th centuries. Compared with early 20th century data, it can be seen that the climate in the 13th and 14th centuries was cold. The example shows evidence of cooling in the high latitudes of Eurasia.

Many glass beads have been found at archaeological sites in Hokkaido Prefecture. Two possibilities are pointed out in Japanese and Russian documents regarding the distribution of the glass beads. One theory is that they came from Honsh?, and another suggests that they were from the lower Amur Basin and came to Hokkaido through Sakhalin Island. Since the extent of literary research for these two possibilities are limited, we decided to take a different approach to obtaining information that would lead to finding the origin of the beads. We performed chemical analyses of glass beads discovered in Hokkaido by using scanning electron microscope (SEM) with energy dispersive X-ray spectrometry (EDX). Soda-lime glass beads were discovered at the sites of Epi-Jomon to Satsumon cultures in Biratori Town. Lead glass beads were discovered at those sites for dates before 1667, and soda-lime glass beads were discovered for dates after 1667 at the same sites.

In this study, chemical compositions were reexamined on the glass beads excavated from the Usu-Oyakotsu site in Date City, Hokkaido. As a result, it was possible to clarify that these glass beads are composed of potash lime glass and potash lead glass. In particular, it is noteworthy that the majority was potash lime glass. In addition, it became clear that the potash lime glass is divided into two compositional types, lead - containing type and lead - free type. Especially for lead - containing type, it might be one of the features of potash lime glass distributed in the early Ainu culture period.

Many glass beads have been found at archaeological sites in Hokkaido. We performed chemical analysis of glass beads discovered in Hokkaido by using scanning electron microscope (SEM) with energy dispersive X-ray spectrometry (EDX). Some glass beads were discovered from the Washinoki Site at Mori Town. These glass beads belong to Epi-Jomon culture and these are made from soda-lime glass.
