Trial Survey Method of Electro Magnetic and Soil Material on Medieval Towns and Castles Centering on the Method of detecting Invisible Feachers

Apart from the survey on medieval site, we also carried it out on Kofun in Himi city and in Toyama city. We aimed at searching moats which surrounded them. We found them out successfully. The excavation at Tosaminato site will continue for over ten years, with the aim of reconstructing the town site in its medieval phase and the castle as it was in the ancient period. We will not be able to excavate all of the area, however, what we need to do first is predict the archaeological features in advance. In that point, for this kind of wide area site, geophysical survey is remarkably essential before planning the research agenda.
