Japan is a megalithic culture many of

the megaliths in Japan have never really

been properly

studied this doesn't happen naturally

this is a man-made

structure unless there's any doubt that

it's man-made let's get up close and

look at it it's made of individual

blocks of

stone having gone to all the work of

creating huge megalist like this they

wouldn't have wasted

them imagine standing before a vast

network of subterranean Caverns

extending thousands of square meters

deep into the Earth carved from the

unique volcanic tough known as Oya Stone

when these Caverns at the Oya stone

quarry in utom were first created it

seemed nearly impossible for humans of

that era to shape such an immense and

complex structure yet somehow they did

with nothing more than rudimentary tools

and sheer human effort I want to know

what else is going to be found that

hasn't been investigated yet at all

we're just touching the edge of a huge

mystery did this really happen or was

there more at play here than meets the

eye fast forward to today and despite

our Advanced Technology and Engineering

prowess replicating such a feat remains

a formidable challenge this Marvel of

both natural formation and human

endeavor invites us to explore its

depths uncovering the secrets held

within its echoing Chambers and imposing

walls I think we're confronted by an

enormous mystery with megalithic sites

all around the world uh and we don't

understand them properly

the Oya stone quarry with its deep

historical roots in Japan's

architectural landscape offers a

fascinating glimpse into the evolution

from localized resource extraction to

significant industrial use the exact

Discovery date of the Quarry isn't well

documented but evidence suggests that

small scale extraction of Oya Stone

began around the hyen period I think the

dating of quite a number of megalithic

sites needs to be

reconsidered it quickly became popular

for its unique properties particular

ularly its ease of carving when freshly

quarried which made it ideal for

constructing religious structures like

temples and shrines as well as for

creating detailed statues for these

sites as we move into the Ado period the

role of Oya Stone expanded dramatically

this was a time of relative peace under

the Tokugawa shogunate marked by

urbanization and the burgeoning need for

more durable building materials Oya

Stone known for its enhanced fire

resistance became a critical resource in

constructing robust fire resistant walls

particularly in Ido modern day Tokyo

which was prone to frequent fires

wildfires are what you expect when you

have a bit of a comet air bursting uh up

above you the quarry's activities

intensified with technological

advancements in mining such as the

introduction of better chiseling tools

and more systematic methods for removing

large stone blocks the expansion of

cities during this period necessitated

large quantities of durable materials

and oil Stone was extensively used not

just for building walls but also for

Bridges and other infrastructure

projects that required materials that

could withstand both the elements and

the threat of fire as demand surged the

shogunate implemented stricter

regulations to manage the Quarry

operations effectively ensuring the

extraction rates were sustainable and

that the stone remained available for

future

Generations when we compare o stone with

European Limestone which was used for

similar purposes we noticed both

materials share the property of

hardening over time which is ideal for

constructions meant to endure however

while limestone in Europe was often

chosen for both its practical and

aesthetic qualities Oya Stone's use in

Japan was deeply intertwined with the

country's cultural and religious

practices reflecting a unique blend of

utilitarian and spiritual values this

distinction highlights not only the

functional importance of O Stone but

also its role in shaping the cultural

heritage of Japan the o stone quarry is

celebrated for its production of

oilstone a unique type of green tough

volcanic rock known for its distinctive

qualities this Stone has been a

Cornerstone in Japanese architecture and

art for centuries let's dive deep into

its Rich historical tapestry and uncover

some fascinating details along with a

compelling Theory tracing back to around

800 ad during the early hyen period the

operations at the O stone quarry began

in an era marked by the consolidation of

power in the Japanese Imperial Court and

a cultural boom influenced heavily by

the Chinese Tang Dynasty Aesthetics

initially o Stone was primarily used for

constructing the foundations and lower

structures of buildings in local

Villages largely because of its

accessibility and the ease with which it

could be carved when freshly quarried

what makes Oya Stone particularly

intriguing is its unique physical

property it is relatively soft when

first quarried but hardens upon exposure

to air this feature allows ancient

Builders to initially carve it with ease

and as it hardened it would transform

into a durable structural element not

only did its warm beige to light gray

Hues and porous texture enhanced the

natural Aesthetics of traditional

Japanese buildings but it also provided

excellent insulation properties as the

hayen period progressed the cultural

center of Japan shifted to Kyoto

increasing the architectural demand for

Oya Stone possibly spurred by its fire

resistant properties an essential

feature in an era prone to wooden

structure fires by the late highend

period the Stone's reach extended Beyond

local regions finding its way into more

significant and prestigious construction

projects across Japan such as temples

shrines and statues I can't help

thinking Time Capsule that there was an

intention to preserve this ancient texts

often highlight its use in substantial

state sponsored construction projects

suggesting a growing importance in the

architectural landscape of the time

the rising demand for Oya Stone led to a

significant expansion of the Quarry

operations quarrying techniques evolved

from simple manual methods to more

organized mining activities involving

larger labor forces this expansion not

only catered to the increasing

architectural demands but also became a

focal point for Local Economic

Development providing numerous jobs and

contributing to the growth of

surrounding communities an intriguing

theory about the Oya stone quarry is

that it was discovered and initially

developed under the aices of the

Imperial family of Japan this Theory

suggests that the imperial family might

have used the Quarry to demonstrate

their divine right to rule by

constructing temples and palaces with

this Unique Stone ancient cultures all

around the world preserved a memory of a

high civilization the frequent use of O

Stone in Imperial and Noble projects

during the hen period supports this

Theory the distinctiveness of the stone

and the Grandeur it imparted to

buildings would have symbolized the

celestial and exalted status of the

emperor aligning perfectly with the

Imperial Ambitions of the time this

fascinating hypothesis adds an

additional layer of historical and

cultural significance to the already

rich Narrative of the Oya stone quarry

nestled in utsunomiya tochigi prefecture

the oer stone quarry offers more than

just a peak into the world of mining it

presents a fascinating interplay of

geology history and Acoustics let's

delve into the Intriguing details of its

Underground Caverns their extensive

history and unique

characteristics spanning an impressive

20,000 square m these Caverns form a

vast Subterranean Network that has been

shaped over centuries in some areas they

plunge as deep as 60 M equivalent to a

20-story building this vast and varied

landscape not only offers a glimpse into

the Earth's depths but also tells the

tale of its past through the very walls

that form it etched with the marks of

pickaxes and chisels the cavern walls
