Summary: On the fields of Puukohara and Honaunau, the Big Island of Hawaii, there are several huge types of rock features, "heiau", heaped rock formations dedicated to divinities and spirits. The biggest one is about 2 meter high, 30 meter wide and 50 meter long, and it looks like a big swimming pool built on the top of a hill. The rock formation used to be a sacred place, where religious ceremony or some rituals were held by native priests of a certain tribe. The oldest type of heiaus can be seen at the King's trail petroglyph field, Waikoloa, Hawaii, where abandant of petroglyphs are carved. There is no record of who made those rock features and rock art, but local legends say that a certain kind of tribes, Minehune, little people, were the builder of those rock features.

According to the heaped up studies by scholars of University of Hawaii and U.C.L.A. as well as the staff of the Bishop Museum, Honolulu, several of Hawaiian heiaus were built by the seafarers, who came from the Tahiti island and other Polynesian islands in the latter stage of prehistoric ages, while most of original type of heiaus and petroglyphs are said to have been made by those who came from the west of the Pacific Ocean in latter part of prehistoric ages, although their home-land has not been known yet.

It is an interesting fact that there are 8 similar heiaus in Japan, which lies to the far west of Hawaiian islands. Scholars of the Japan Petrograph Society and Japan Academic Center have made remarkable finds at 8 locations in Japanese islands, where Hawaiian types of rock formations and similar petroglyphs can be seen. This paper aims at suggesting a home-land of the first people, who reached Hawaiian island and built such heiaus and carved Hawaiian petroglyphs. Comparative studies on Hawaiian heiaus (rock formations) with Japanese ones will be sure to surprise most of scholars, who used to believe that Hawaiian rock features and rock art came from some Polynesian islands or from some south Pacific islands, because they had no idea of similar ones e4xist in Japan, far west of the Pacific ocean. When we think of the circulation of Pacific currents, which might have helped the seafaring people more than 6500 BP, we will safely reach a definite conclusion that boat people must have crossed the Pacific somehow to settle their new found islands and made rock formations, rock art, taking after their custom of their home-land.

This contribution paper is a beginning of a comparative study to examine the homeland of those first settlers on the Hawaiian islands, but I am sure that in very near future, some colleagues du succeed in similar studies as I am going to suppose here in my paper.
