The Ichigaya Memorial Hall and Demon Slayer: Kimetsu no Yaiba
The Ichigaya Memorial Hall, located in Ichiyamamoto-cho, Shinjuku Ward, Tokyo, is known among “Demon Slayer: Kimetsu no Yaiba” fans as a sacred pilgrimage site modeled after the “Demon Slayer Corps Headquarters.” Despite its unique location within Defense Ministry grounds, it is a facility open to general visitors, attracting many fans.
The Demon Slayer Corps Headquarters depicted in the work is also portrayed as the Ubuyashiki Estate where Ubuyashiki Kagaya (the Master) resides, and as a traditional Japanese architecture with spacious tatami rooms and a beautiful Japanese garden, it plays an important role in the story. The dignified presence of the Ichigaya Memorial Hall as a historic building and its traditional Japanese architectural style overlap with the atmosphere of the work’s world, leading to its recognition as a sacred site.
Common Points with the Image of the Demon Slayer Corps Headquarters
The reason the Ichigaya Memorial Hall is noted as the model site for the Demon Slayer Corps Headquarters lies in its architectural style and historical background. The formality of a Japanese military facility continuing from the Meiji period, its solemn atmosphere, and the setting of a special place not easily accessible to ordinary people correspond with the depiction of the Demon Slayer Corps Headquarters in the work.
Within the work, the Demon Slayer Corps Headquarters is depicted as the base of a secret organization with strong influence despite being unrecognized by the government. This image of “a public yet highly secretive place” overlaps with the character of the Ichigaya Memorial Hall located within Defense Ministry grounds.
History and Cultural Value of Ichigaya Memorial Hall
From Military Academy to Defense Ministry
The history of the Ichigaya Memorial Hall dates back to the Meiji period. During the prewar years, this site housed the Imperial Japanese Army Academy, the Imperial General Headquarters Army Section, and the War Ministry. It functioned as the center of Japan’s military education and national defense, playing an extremely important role in Japan’s modern history.
The Imperial Japanese Army Academy, as the highest educational institution for training Army officers, produced many military personnel. Its buildings possessed the highest-level technology and formality of the time, and special facilities were prepared for imperial visits.
The Far Eastern International Military Tribunal (Tokyo Trial) Venue
In 1946, following World War II, the Far Eastern International Military Tribunal (Tokyo Trial) was held in the “Lecture Hall No. 1” (the predecessor of the Ichigaya Memorial Hall). This tribunal, serving as an international court to try Japan’s wartime leaders, was a historically significant event in world history.
The present Ichigaya Memorial Hall is a relocated and restored version of the lecture hall used as the courtroom for the Tokyo Trial. To preserve the value of the historic building, when the Defense Ministry Headquarters Building A was constructed, the former Building No. 1 was reconstructed as a memorial hall.
Connection to the Mishima Yukio Incident
The Ichigaya Memorial Hall is also known as the place where author Mishima Yukio committed suicide in 1970. This incident is one of the symbolic events in Japan’s postwar history, further elevating the historical importance of the Ichigaya Memorial Hall.

Highlights of Ichigaya Memorial Hall
The Grand Lecture Hall (Tokyo Trial Courtroom)
The greatest highlight of the Ichigaya Memorial Hall is the Grand Lecture Hall where the Far Eastern International Military Tribunal was held. This space recreates the appearance of the courtroom at that time, with judges’ benches, defendants’ seats, witness stands, and other fixtures arranged.
The ceiling of the Grand Lecture Hall is high, and a solemn atmosphere permeates the space. Considering that the trial held here determined the direction of postwar Japan, one cannot help but feel the weight of history. For Demon Slayer fans, this space holds special meaning as it evokes scenes of the Master holding conferences with the Pillars.
The Former Imperial Reception Room
The “Former Imperial Reception Room” used as a resting space for the Emperor during the Imperial Japanese Army Academy era is preserved as a high-class Japanese room. The tatami-floored room, tokonoma alcove, and carefully maintained furnishings convey the beauty of Meiji-era Japanese architecture to the present day.
The atmosphere of this room overlaps with the image of the Ubuyashiki Estate’s Japanese rooms. Viewing it while imagining scenes such as when Tanjiro and the others first pay respects to the Master or when the Pillar Assembly is held provides even deeper impressions.
The Former Army Minister’s Office
The former Army Minister’s office, used as the Imperial Japanese Army Academy Headmaster’s office, is also available for viewing. The heavy wooden furniture and dignified interior design convey the majesty of a place where the military’s highest-ranking officials conducted their duties.
This room transmits the tension of a place where the head of an organization makes crucial decisions. Imagining the Master leading the Demon Slayer Corps making important judgments regarding battles with demons enhances immersion in the story.
Exhibition Room
The exhibition room adjacent to the Ichigaya Memorial Hall displays materials related to the history and activities of the Defense Ministry and Self-Defense Forces. Photographs from the Imperial Japanese Army Academy era, materials related to the Tokyo Trial, and the history of the Self-Defense Forces from its establishment to the present can be viewed among valuable historical materials.
In the exhibition room, one can learn about the value of peace and the importance of protecting what must be protected through Japan’s history of national defense. This resonates with a theme of “Demon Slayer”: the battle to protect those dear to us.

Attractions of Ichigaya Memorial Hall That Demon Slayer Fans Should Know
A Place Where History and Story Intersect
The greatest charm of the Ichigaya Memorial Hall lies in how it allows visitors to feel the world of “Demon Slayer” while being an actual historic building. By imagining the activities of the fictional Demon Slayer Corps in a place stamped with Japanese history from the Meiji through Showa periods, one’s understanding of the work deepens.
Within the work, the Demon Slayer Corps is depicted as an organization unrecognized by the government, yet hints suggest it has deep connections with the Meiji government. By visiting the Ichigaya Memorial Hall, an actual Meiji-era military facility, one can feel the historical background of the work realistically.
Architectural Beauty and the Inheritance of Japanese Culture
The architectural style of the Ichigaya Memorial Hall exemplifies the fusion of Western and Japanese architecture during the Meiji period. The space where Western-style architectural grandeur of the lecture hall coexists with the purely traditional Japanese architecture of the Former Imperial Reception Room truly embodies the cultural characteristics of the Meiji era.
Similarly, “Demon Slayer” is set in the Taisho era, a period of East-West syncretism, and the historical background of this era—where traditional Japanese culture and waves of modernization intersect—gives depth to the narrative. Visiting the Ichigaya Memorial Hall allows one to sense the atmosphere of this era firsthand.
Special Experience as a Sacred Pilgrimage
The Ichigaya Memorial Hall provides a unique experience different from other sacred pilgrimage sites. Being able to view a location within Defense Ministry grounds normally inaccessible to the general public, and being able to immerse oneself in the work’s world while learning Japanese history, is a valuable experience unavailable elsewhere.
During the viewing tour, visitors can listen to detailed explanations from guides. Understanding the historical background before reviewing the work may bring new discoveries.
Precautions and Etiquette When Viewing Ichigaya Memorial Hall

Comparison of Ichigaya Memorial Hall with Other Demon Slayer Corps Headquarters Candidates
Differences from Hoppo Bunka Museum (Niigata Prefecture)
The most famous model site for the Demon Slayer Corps Headquarters (Ubuyashiki Estate) is the “Hoppo Bunka Museum Rich Farmer’s Mansion” in Niigata City, Niigata Prefecture. This facility, with its extensive tatami rooms and beautiful Japanese garden, is said to be closest to the architectural style of the Ubuyashiki Estate as depicted in the work.
The Hoppo Bunka Museum allows visitors to view the beauty of purely Japanese architecture and the lifestyle of a wealthy farmer, with many elements that visually match the depictions in the work. In contrast, the Ichigaya Memorial Hall corresponds with the image of the Demon Slayer Corps Headquarters in terms of historical background and organizational formality.
Characteristics of Each Sacred Site
Hoppo Bunka Museum:
- Visually closest to the Ubuyashiki Estate
- Outstanding beauty of Japanese gardens
- Photography is relatively unrestricted
- Access is within Niigata City
Ichigaya Memorial Hall:
- Historical background corresponds with work’s setting
- Location suggests connection with government
- High security aligns with image of secret organization
- Good access in central Tokyo
Visiting both allows visitors to experience different aspects of the Demon Slayer Corps Headquarters. At the Hoppo Bunka Museum, one experiences visual beauty and Japanese atmosphere; at the Ichigaya Memorial Hall, one experiences organizational formality and historical weight.
Enjoying the Experience After Viewing Ichigaya Memorial Hall
Purchasing Souvenirs at the Defense Ministry Gift Shop
The viewing tour includes a gift shop where one can purchase merchandise related to the Defense Ministry and Self-Defense Forces. Self-Defense Force goods and limited items available only here are available.
Purchasing souvenirs related to the Ichigaya Memorial Hall or Defense Ministry as a memento of the sacred pilgrimage is also a good idea. Postcards, clear files, and other reasonably priced items are abundant.
Dining Near Ichigaya
After viewing, enjoying a meal near Ichigaya is also recommended. Around Ichigaya Station, there are various restaurants including Japanese cuisine, Western cuisine, and cafes.
By dining at a retro cafe conveying Taisho-era atmosphere or a Japanese restaurant, one can savor the lingering emotion of the sacred pilgrimage.
Photography Spots
While photography is restricted inside the Ichigaya Memorial Hall, memorial photographs are possible in permitted areas such as near the Defense Ministry’s main gate. Taking photographs of the exterior as a souvenir of the visit is a good idea.
However, when photographing, always follow staff instructions, and absolutely refrain from photographing in prohibited areas.
The World of Demon Slayer and the Historical Background of Ichigaya Memorial Hall
Japan in the Meiji and Taisho Periods
The setting of “Demon Slayer: Kimetsu no Yaiba” is the Taisho period (1912–1926), but the Demon Slayer Corps’ history spans over a thousand years. The predecessor of the Ichigaya Memorial Hall, the Imperial Japanese Army Academy, was established in the Meiji period, coinciding precisely with the work’s era.
During this period, Japan faced two challenges: rapid modernization and the preservation of traditional culture. Similarly, the work depicts coexistence of modern civilization such as steam locomotives and Western-style buildings alongside traditional culture such as swordsmanship and traditional clothing.
The Demon Slayer Corps as an Organization and the Military
The Demon Slayer Corps is an organization with a hierarchical system, composed of warriors who have undergone rigorous training. This point is similar to actual military organizations. Considering that the Ichigaya Memorial Hall formerly functioned as the Imperial Japanese Army Academy, there are common points in organizational management as well.
Within the work, the Demon Slayer Corps is managed under strict order and discipline, with figures called “Pillars,” the highest-ranking swordsmen. Such organizational structure is thought to have been influenced by the Meiji-era Japanese military.
Tips for Maximizing Enjoyment of Sacred Pilgrimage
Prior Preparation
It is recommended to review the work before visiting the Ichigaya Memorial Hall. Particularly, it is beneficial to confirm the following episodes before visiting:
- The scene where Tanjiro first visits the Demon Slayer Corps Headquarters
- The Pillar Assembly scene
- Conversations between the Master and the Pillars
- Scenes depicting the Ubuyashiki Estate in general
By having these scenes in mind, the emotion experienced when actually visiting the Ichigaya Memorial Hall increases.
Historical Learning
Learning about the historical background of the Ichigaya Memorial Hall beforehand makes the viewing more fulfilling. The following topics are worthwhile to research:
- The history and role of the Imperial Japanese Army Academy
- An overview of the Far Eastern International Military Tribunal (Tokyo Trial)
- Military history of Japan in the Meiji and Taisho periods
- The establishment and evolution of the Defense Ministry
Viewing with historical knowledge allows deeper understanding of the value of the buildings and exhibits.

Recommended Route Example:
Morning: Asakusa sightseeing (experiencing Taisho-era atmosphere)
Afternoon: Ichigaya Memorial Hall viewing tour

The Ichigaya Memorial Hall possesses special value as a “Demon Slayer” sacred pilgrimage site unlike any other. A unique combination of three elements—the special location within Defense Ministry grounds, the formality as a historic building continuing from the Meiji period, and status as the venue for the Far Eastern International Military Tribunal, a world-historic event—creates a one-of-a-kind sacred site.
As a model site for the Demon Slayer Corps Headquarters, where one can experience the formality and secrecy of an organization and feel Japan’s history and tradition, the Ichigaya Memorial Hall is a worthwhile destination to visit.
