Complete Guide to Midono Mejiro Castle | A Thorough Explanation of the Place Where Hosokawa Gracia Was Imprisoned
What is Midono Mejiro Castle?
Midono Mejiro Castle is a historical castle site located in Yasaka-cho, Kyotango City, Kyoto Prefecture. This site holds significant importance in Japanese history as the place where Hosokawa Gracia (Akechi Tama, Tamako), known as a tragic heroine of the Sengoku period, was imprisoned.
Also known as Goten Yashiki, this castle site is where Tamako, the wife of Hosokawa Tadaoki, was forced to live in seclusion for about two years immediately after the Honnoji Incident in 1582. Even today, many history enthusiasts are interested in what kind of life she led in this remote mountainous area of the Tango Peninsula.
How to Pronounce Midono Mejiro Castle
The correct pronunciation of “Midono Mejiro Castle” is “Midono Mejiro”. The place name “Ajino” is pronounced “Midono,” and “Mejiro” is pronounced “Mejiro.” The stone monument at the site is inscribed with “Ajino Mejiro Ato” (Ajino Mejiro Ruins), which is correctly pronounced “Midono Mejiro Ato.”
This pronunciation has been established locally for a long time, and along with its counterpart, “Ojiro” (male castle), it is an indispensable part of the history of this region.
The History of Hosokawa Gracia and Ajino Mejiro Castle
The Honnoji Incident and the Circumstances of Her Imprisonment
The Honnoji Incident, in which Akechi Mitsuhide assassinated his lord, Oda Nobunaga, at Honnoji Temple on June 2, 1582 (Tensho 10), is one of the most famous events in Japanese history. This incident drastically altered the fate of Mitsuhide’s daughter, Tama (later Hosokawa Gracia).
Tama’s husband, Hosokawa Tadaoki, fearing his involvement in his father-in-law Akechi Mitsuhide’s rebellion, and also because his wife was the daughter of a rebel, made the agonizing decision to divorce Tama. However, instead of a complete divorce, he chose to confine Tama to “Tanba no Uchiyama Santono,” or Mitono, in the mountains of Tango Province.
Two Years of Seclusion
Life at Mitono Castle was completely different from the glamorous life of a daimyo’s wife that she had previously enjoyed. It is presumed that her days spent in a remote mountain area with only a limited number of ladies-in-waiting were mentally and physically demanding.
The period of confinement lasted approximately two years. During this time, Tama is said to have spent her time reading and praying, and it is believed that the spiritual foundation for her later conversion to Christianity was formed during this period. Her solitary life in the mountains may have deepened her inner self.
In 1584, thanks to the intercession of Toyotomi Hideyoshi, Tama was released from Ajino and allowed to return to her husband, Tadaoki. Afterward, she was baptized into Christianity and received the baptismal name “Gracia” (meaning “grace”).
The Later Life of Hosokawa Gracia
After returning from Ajino, Gracia lived in Osaka. During the Battle of Sekigahara in 1600, she refused to become a hostage of Ishida Mitsunari and met a tragic end at the Hosokawa residence in Osaka. This tragic death elevated her to the status of a legendary figure in history.
Structure and Characteristics of Ajino Women’s Castle
Differences Between Women’s and Men’s Castles
There are two castle ruins in Ajino: “Women’s Castle (Mejiro)” and “Men’s Castle (Ojiro).” These two castles had clearly defined roles.
Mejiro (Women’s Castle) is the actual residence of Hosokawa Gracia. Located at the tip of a mountain ridge, it provided a relatively flat living space. As it is also called the Palace Residence, it is believed that buildings for Tama and her ladies-in-waiting were constructed here.
Ojiro (Men’s Castle) was a facility for monitoring and guarding Mejiro. Located a short distance from Mejiro, it was staffed by Hosokawa retainers who monitored Tama’s movements and prevented intrusion from the outside.
This dual structure can be seen as reflecting Hosokawa Tadaoki’s complex feelings of wanting to ensure Tama’s safety while keeping her confined.
Castle Location and Topography
Mitono Mejiro is located in the central, mountainous, and rugged terrain of the Tango Peninsula. Its location in the mountains of Yasaka-cho, Kyotango City, was extremely difficult to access at the time.
The castle ruins were built utilizing the tip of a mountain ridge, showcasing a structure that skillfully takes advantage of the natural terrain. The surrounding area is enclosed by deep valleys and steep slopes, indicating its excellent defensive position.
Even today, the path to the Onnajo Castle ruins requires climbing a mountain trail, allowing us to imagine the route by which Tama was brought to this location.
Current Remains
Currently, there are no clear building remains at the Ajino Onnajo Castle ruins, but traces of flat enclosures and earthworks can be seen.
A stone monument inscribed with “Ajino Onnajo Castle Ruins” stands at the castle site, indicating its connection to Hosokawa Gracia. The area around the monument has been maintained, creating a space where visitors can reflect on history.
Because archaeological excavations have been limited, many details about the layout and structure of the buildings remain unknown. Further investigations are expected to yield new discoveries.

Understanding the historical background before visiting the castle ruins will allow for a deeper appreciation of the site.
Enclosure Remains and Topography
The enclosure remains of Onnajo Castle are a relatively flat space spread out at the tip of the mountain ridge. It is believed that a palace was built here, and that Tama and her ladies-in-waiting lived here.
Although currently covered with trees, careful observation reveals traces of artificial leveling and remnants of earthworks. It can be said to be a valuable historical site for learning about the structure of mountain castles during the Sengoku period.
Surrounding Scenery
From the Ajino Onnajo Castle Ruins, you can enjoy a panoramic view of the Tango Mountains. The environment, surrounded by deep mountains, allows you to relive the feelings of loneliness and confinement that Tama experienced at the time.
At the same time, you can enjoy the beauty of nature throughout the seasons. The fresh greenery of spring, the deep green of summer, the autumn foliage, and the snowy landscape of winter—the nature of Ajino, which shows different expressions depending on the season, adds further appeal to the historical value of the castle ruins.

This event vividly illustrates the reality that women in the Sengoku period were often treated as political tools.
