Japanese Mini-Pyramids

In a recent issue of the Ancient Ameri can, Editor F. Joseph presented an intriguing photograph of a precisely sculpted pyramid crouching incongruously amid the thick trees and bushes of Mount Kasagi, in north-central Japan. Being only 7 feet high and 14 feet along its base, this edifice hardly challenges the classical pyramids of Egypt and Mesoamerica. It is, though, skillfully crafted from solid granite -- almost a work of art. Age, sculptors, and purpose seem to be unknown.

Japanese call it a "trigonon." It is not alone, for four more can be found strung along a ridge of Mount Kasagi about 100 meters apart.

(Joseph, Frank; "Ancient Wonders of Japan," Ancient American, no. 17, p. 27, 1997.)

Comment. We have not stumbled across reference to these "trigonons" before. Hopefully, some of our Japanese readers will enlighten us further.

Reference. See our Handbook Ancient Man for much more on pyramids, stone circles, and other ancient structures. This book is described here.

Science Frontiers Sourcebook Project Reviewed in:


  • "A sourcebook of unexplained phenomena is therefore a valuable addition to a collection of scientific literature. William R. Corliss has provided this in the past with his source books of scientific anomalies in several subjects, and now he has provided it for astronomy. He has done an excellent job of collecting and editing a large amount of material, taken in part from scientific journals and in part from scientific reporting in the popular or semi-scientific press." -- "The Mysterious Universe: A Handbook of Astronomical Anomalies", reviwed by Thomas Gold, Cornell University, in Icarus, vol.41, 1980

  • "An interesting, systematic presentation of unusual weather [..] This book is recommended for a general audience" --"Corliss, William R., Tornados, Dark Days, Anomalous Precipitation, and Related Weather Phenomena, Sourcebook Project, 1983.", revieweed in Choice, September 1983
  • "..the science is necessarily somewhat speculative, but Corliss's symthesis is based on reputable sources." -- "Corliss, William R. (Compiler). Lightning, Auroras, Nocturnal Lights, and Related Luminous Phenomena" reviwed by Joseph M. Moran, Univ. of Wisconsin in Science Books and Films, Sep/Oct 1983

  • "Before opening the book, I set certain standards that a volume which treads into dangerous grounds grounds like this must meet. The author scrupulously met, or even exceeded those standards. Each phenomenon is exhaustively documented, with references to scientific journals [..] and extensive quotations" -- "Book Review: The moon and planets: a catalog of astronomical anomalies", The Sourcebook Project, 1985., Corliss, W.
