What exactly is the Freemasons?

Freemasonryremains a mystery, it is often whispered about as a secret society constantly embroiled in conspiracy theories. However, it is actually considered a fraternal organization that teaches and shares fundamental human morality. It is believed to have been founded in Scotland or England in the late 16th or early 17th century, and today it is said to have around 6 million members worldwide.

In English, individual members are called Freemasons or Masons, and when referring to the organization it is called Freemasonry, or simply Masonry

While the specific activities of the Freemasons remain largely secret and shrouded in mystery, the official website of the Grand Lodge of Japan states that they engage in charitable activities such as establishing schools and providing financial support to charitable organizations

The Freemasons were an organization that aimed to "realize the ideal of brotherhood among all humanity" and "realize the true and highest ideal that civilization possesses," and it is said that various figures, including politicians, businesspeople, and cultural figures throughout history, were members of the Freemasons

For some reason, there is a stone monument that appears to have the symbol of the mysterious secret society, the Freemasons, engraved on it at the site of Sendai Castle (Aoba Castle)

"Upward-pointing triangle right angle ruler and compass" engraved on a stone monument near the site of the Otemon Gate

From the center of Sendai city, go straight on Aoba-dori. After crossing the Ohashi Bridge, you will come to a three-way intersection near the Sendai City Museum on your left. If you go straight at the intersection, you will reach Sendai Castle's Otemon Gate Tower, and if you turn right, you will head towards the Miyagi Museum of Art

The stone monument is located in the green area in the center of this three-way intersection

It's a little hard to see in the wider shot, but the small cube-shaped object in the center of the photo is what's commonly known as the "Freemason Stone." The Otemon Gate side turret of Sendai Castle can be seen in the background. The location is also registered on Google Maps under the name "Freemason Stone."

Upon closer inspection, a distinctly unusual mark is visible, clearly not resembling any remnants of Sendai Castle (Aoba Castle). It depicts an upward-pointing triangle, a right-angle ruler and compass, and the letter "G" in the center. It bears a striking resemblance to the symbol commonly known as the Freemason symbol

The combination of a ruler and compass is known as a representative symbol of Freemasonry. The "G" in the center is generally interpreted as representing "God" or "Geometry," but its meaning and symbolism vary depending on the organization and region

The qualification for joining the Freemasons is to have some kind of faith

While the term "Freemasonry" is certainly intriguing, traditional Freemason organizations, including the Grand Lodge of Japan, may require a belief in a supreme being as a condition for membership. However, qualifications and rules vary depending on the Grand Lodge that oversees the organization

Of the 6 million members worldwide, 150,000 are under the jurisdiction of the Grand Lodge of Scotland and the Grand Lodge of Ireland, and 250,000 are under the jurisdiction of the Grand Lodges of the Commonwealth. Additionally, 2 million belong to the Grand Lodges of the United States, andthe number of members under the Grand Lodge of Japan is approximately 1,500, with about 250 being Japanese.

Why is it located at the Sendai Castle ruins? Does it hold the key to the history of the Sendai Castle ruins (Aoba Castle ruins)?

Why is there such a Freemason stone monument at the site of Sendai Castle (Aoba Castle)? The mystery can actually be solved by going back in history

Sendai Castle (Aoba Castle) has a history of being occupied by Allied occupation forces after the war, and it is said that there was a U.S. military"Freemason lodge in Sendai". There is a theory that this stone may be a relic related to the Freemason lodge established by U.S. military personnel stationed in this area after the war.

However, no official documents indicating the stone's formal name, installation date, or purpose can be found, so it cannot be definitively identified as the "foundation stone of the Sendai Lodge."

After the war, the area around the former second bailey of Sendai Castle was used as "Camp Sendai" by the U.S. military and was returned to Japan in 1957. Subsequently, the Kawauchi Campus of Tohoku University was developed on the site of the second bailey. Meanwhile, the site of the main bailey is home to the Miyagi Prefecture Gokoku Shrine and other sites

The mysterious "Freemason" monument could be seen as something that evokes the post-war era when the US military was present

that Date Masamune, the first lord of the Sendai domain, was a member of the Freemasons, but that possibility seems unlikely.

It is said that 2 million Freemasons belong to the Grand Lodge of the United States, so there must have been a US military "Sendai Lodge" there when the US military was stationed there

It's amazing how the history of Sendai Castle Ruins (Aoba Castle Ruins) can be unraveled from a place like this
