Outline of Final Research Achievements

I did a philological, archeological and geological research on quarries for building Osaka Castle in Shodoshima Island. I collected historical documents, examined estimated candidates for quarry sites in the island, and compared them to determine which of them were actual quarries. In particular, I investigated the coast closely to know from where stones were carried out of the island, finding out new quarries and relevant stones sunk under the sea.
I made a report on the results of this research. The report includes historical documents set in type, photographs of rubbing of engraved stones and plug-and-feather holes, and many other graphics. It also includes four academic papers so that one can understand details about quarries on Shodoshima Island. Since there have been no reports concerning the whole island, I believe this will be a fundamental document for future study.

Academic Significance and Societal Importance of the Research Achievements

小豆島の石丁場に関して、文献史料と考古学的調査を併せた調査研究により、従来不明であった石丁場の所在地が確認されるとともに、刻印石や残石の発見により新たな石丁場が確定された。
報告書により多くの情報を提供、島民に地域に残る文化財をいかに保全していくかを考える材料にしている。また「備讃諸島石の島の物語」として小豆島の石の文化が日本遺産に認定されたが、当該研究がそこに至るうえで寄与したものといえる。
