To provide against the invasion from the Korean Peninsula or the Asiatic Continent, a lot of ancient castles had been constructed on the hills in Northern Kyushu and at the seasides of the Inland Sea since the 7th century to the Nara era. They are those hilly castles which had been described in the documents, as well as the “Kogoishi”, although its original form had been unclarified. Discussions had been repeated about the “Kogoishi” since the Meiji era, and finally the result of the recent excavation survey verified them as the castles on the hill.In this treatise they are histrico-geographically followed up. Having examined each of them for their position and function etc., it had turned out clear that they located at the spots where command a very fine view and are advantageous to be able to occupy the important military and communicative areas. In addition to it, they are usually constructed so abutting to the provincial capital “Kokufu” that it is easily surmised that they must be fortified with a purpose of defending it in emergency. Moreover, the castles on the hill together with the “Kogoishi” seemed to be equipped with the facilities of signal fire as transmission means of alarm.At any rate, unlike the citadel “Josaku” in the Tohoku district, it is to be concluded that the ancient castles on the hill in the Western Japan were, for their position, fortification and scale, systematically and intentionally established and disposed from a national point of view.
