A new investigation by Matt LaClear

A mountain in Japan where ancient mythology, Pentagon data, and Nephilim history converge.

The Stronghold of Mount Hiba traces twenty independent variables converging on one location in Hiroshima Prefecture — from magnetic reversal basalt and megalithic structures to cryptid sightings, UAP data, and the long absence of Christian witness in the surrounding mountains.

Evidence-first. Intellectually honest. Never sensationalist.

  • Geology, mythology, and anomaly data in one investigative frame
  • Built for skeptics, seekers, and believers willing to weigh evidence
  • Drawn from publicly available, independently verifiable sources

A dossier on geology, mythology, anomalous phenomena, and spiritual territory in western Japan.

The synopsis

The mountain no one talks about

There is a mountain in Japan that nobody talks about.

Mount Hiba sits in the rural interior of Hiroshima Prefecture — far from the bullet trains and neon lights. It appears in the Kojiki, the oldest surviving book in Japan, as the burial place of a goddess sealed beneath the earth with a massive stone. The stone is still there. You can hike to it.

But that is only the beginning. Mount Hiba is composed of basalt formed during a period when the Earth’s magnetic field was reversed. Compasses behave strangely on its slopes. The summit is a circular stone-paved mound with a central megalith, ringed by bamboo and yew associated with warding, death, and the underworld in cultures separated by oceans.

Since 1970, witnesses have reported a silent, foul-smelling creature on the mountain they call the Hibagon. Nearby peaks carry names like Demon Screaming Mountain. The wider region overlaps with concentrated UAP reports, ancient ironworking traditions, nuclear trauma, and a 475-year absence of Gospel witness in the mountains around Shobara.

Matt LaClear did not set out to write a book about spiritual warfare. He set out to learn about a mountain. Every thread he pulled led to three more. This book is the result.

The evidence grid

Twenty variables. One location.

This is not one anomaly in isolation. It is an accumulation of geological, historical, biological, mythological, and spiritual data points that refuse to stay in separate boxes.

01

Reversed-polarity basalt

Mount Hiba’s basalt formed during the Matuyama Reversed Chron.

02

Compass anomalies

Witnesses and geological context point to magnetic disorientation on the slopes.

03

Stone-paved summit mound

The peak presents as a circular paved structure rather than a purely natural summit.

04

Goryo megalith

A central sealing stone tied to local memory of a blocked underworld entrance.

05

Onmyotake bamboo

A rare bamboo associated in commentary with animals avoiding the summit zone.

06

Yew tree colony

Death-associated trees cluster around the summit in an unusually symbolic arrangement.

07

Mount Ashitake geometry

A neighboring mountain presents pyramid-like geometry from multiple vantage points.

08

Demon Screaming Mountain

Mount Kigyo features a dolmen, altar complex, and ominous ritual associations.

09

Tatara ironworking

Ancient metallurgy surrounds the site, inviting comparison with older sacred-tech traditions.

10

Astronomical alignments

Megalithic placements appear to preserve deliberate sightlines and directional intent.

11

Kojiki underworld narrative

Japan’s oldest book anchors a sealed underworld story to this exact geography.

12

Izumo mythology

Mount Hiba sits on the edge of one of Japan’s most mythologically charged regions.

13

Hibagon sightings

Witness reports of a silent non-human figure span 1970–2025.

14

AARO UAP hotspot data

Pentagon releases place western Japan inside a highly active aerial-anomaly corridor.

15

Nuclear corridor correlation

Hiroshima, Nagasaki, and Fukushima form a disturbing pattern near the anomaly zone.

16

Mount Senganmori parallel

A separate Japanese anomaly site offers structural and phenomenological parallels.

17

Nagasaki Christians destroyed

The region’s strongest historic Christian center was devastated on August 9, 1945.

18

475-year Gospel absence

No sustained Christian witness has taken root in the mountains around Shobara.

19

Kumano Shrine / Tengu trees

Nearby guardian-tree traditions reinforce the region’s spiritual boundary language.

20

Yamabushi gatekeeping

Ascetic mountain traditions preserve the idea of guarded access to sacred terrain.

Twenty variables. One location. The book that lays them side by side.

About the author

A serious investigator following a difficult trail

Matt LaClear didn’t set out to write a book about spiritual warfare. He set out to learn about a mountain.

A researcher and investigator based in Michigan, LaClear spent months tracing the threads that converge on Mount Hiba — from geological surveys and the Kojiki to publicly released Pentagon data and eyewitness reports. The factual claims in the book are drawn from publicly available, independently verifiable sources.

The Stronghold of Mount Hiba is his first book, written for readers willing to weigh evidence carefully and follow the pattern where it leads.
