The Complete Story of Jurakudai: A Thorough Explanation of the History and Remains of the Phantom Castle Built by Toyotomi Hideyoshi
Jurakudai (or Jurakutei) was a magnificent castle-like residence built by Toyotomi Hideyoshi during the Azuchi-Momoyama period on the site of the former Heian-kyo Imperial Palace, known as Uchino in Kyoto. While it symbolized the authority of Hideyoshi, who unified Japan, it was completely demolished after only eight years, leaving its full extent shrouded in mystery. This article provides a thorough explanation of Jurakudai, from its history and scale to its remains and traces that still exist today, incorporating the latest research findings.
What is Jurakudai?
Jurakudai was a residence and castle built by Toyotomi Hideyoshi, who became regent, starting construction in 1586 and completing it in 1587. The name “Jurakudai” embodies the meaning of “gathering pleasures,” and it was a building that symbolized Hideyoshi’s joy at unifying Japan and the peak of his power.
Constructed on the site of the former Imperial Palace of Heian-kyo, this castle was surrounded by moats and stone walls, and equipped with corner turrets, functioning not merely as a residence but as a full-fledged castle. However, following the suicide of his adopted son, Toyotomi Hidetsugu, it was completely demolished in 1595, and its magnificent appearance vanished from history.
Historical Background of the Construction of Jurakudai
Hideyoshi’s Kyoto Policy and Jurakudai
There were multiple political and strategic intentions behind Toyotomi Hideyoshi’s construction of Jurakudai. Having become regent in 1585, Hideyoshi needed to strengthen relations with the imperial court and control the daimyo throughout the country from Kyoto.
Until then, Hideyoshi had used Myōkenji Castle (also known as Myōkakuji Castle) as his base in Kyoto, but he needed a magnificent residence befitting his position as regent. Furthermore, while Osaka Castle was a military base, Jurakudai was positioned as the center of politics and diplomacy.
Construction History and Completion
In February of Tenshō 14 (1586), Hideyoshi began construction of Jurakudai. Maeno Nagayasu was appointed as the construction magistrate, and it was completed in an astonishingly short time of just over a year. This rapid construction involved the mobilization of daimyo from all over the country, and enormous costs and labor were invested.
In September of Tenshō 15 (1587), Jurakudai was completed, and Hideyoshi officially moved into the site. Just one year after its completion, in April of Tensho 16 (1588), Emperor Go-Yōzei visited the palace, and a grand banquet was held, inviting various daimyo. This visit was a perfect opportunity to demonstrate Hideyoshi’s authority to the nation, and Jurakudai became a symbol of Hideyoshi’s regime.
Transfer to Toyotomi Hidetsugu
In Tensho 19 (1591), Hideyoshi relinquished the position of regent to his adopted son, Toyotomi Hidetsugu, and became Taiko (regent). Consequently, Jurakudai was also transferred to Hidetsugu, and Hideyoshi himself moved to Fushimi Castle. Hidetsugu continued to use Jurakudai as his residence and conducted his duties as regent; this period can be considered the palace’s golden age.
The Destruction of Jurakudai and the Reasons Behind It
The Toyotomi Hidetsugu Incident
In 1593, the birth of Hideyoshi’s biological son, Toyotomi Hideyori, put Hidetsugu, his adopted son, in a precarious position. The relationship between Hideyoshi and Hidetsugu gradually deteriorated, and in July 1595, Hidetsugu was suspected of rebellion, exiled to Mount Koya, and ordered to commit seppuku (ritual suicide).
While there are various theories regarding the truth of this incident, it is believed that a combination of factors, including the succession problem arising from Hideyori’s birth and Hideyoshi’s dissatisfaction with Hidetsugu’s conduct, played a significant role.
Thorough Destruction
After Hidetsugu’s death, Hideyoshi ordered the complete destruction of Jurakudai. This destruction was extremely thorough; not only the buildings but also the stone walls and moats were filled in, attempting to erase all traces of Jurakudai. It is said that some of the building materials and stonework from the demolished Jurakudai Palace were reused in the construction of Fushimi Castle and Nijo Castle.
Although Jurakudai Palace lasted only eight years, the thoroughness of its destruction speaks volumes about the depth of Hideyoshi’s anger towards Hidetsugu. Furthermore, this destruction made it difficult to know the exact structure and size of Jurakudai Palace, leaving many mysteries unsolved.
Size and Structure of Jurakudai Palace
Outer Enclosure Scope
Regarding the size of Jurakudai Palace, the exact scope is unknown due to its complete destruction. However, an approximate scope has been estimated based on surveys and excavation results by Kyoto City, as well as records in ancient documents.
Generally, the outer perimeter of Jurakudai Palace is thought to have extended as follows:
- North: Moto-Seiganji Street (near present-day Moto-Seiganji Street)
- East: Horikawa Street (near present-day Horikawa Street)
- South: Oshikoji Street (near present-day Oshikoji Street)
- West: Senbon Street (near present-day Senbon Street)
This area extended approximately 800 meters east-west and 700 meters north-south, with a total area estimated at approximately 560,000 square meters (approximately 170,000 tsubo). While about half the size of Osaka Castle, it was exceptionally large for a castle built in the heart of Kyoto’s city center.
Structure of the Inner Citadel
The internal structure of Jurakudai Palace is estimated from pictorial materials such as the “Jurakudai Folding Screen” and documentary records. It is believed that the main keep (Honmaru) was at the center, surrounded by other enclosures such as the North Citadel (Kita-no-maru), South Second Citadel (Minami-Ninomaru), and West Citadel (Nishi-no-maru).
The main enclosure is said to have been lined with magnificent palaces, and rooms adorned with gold-leafed tiles and painted screens. There are also theories that there was a keep or a similar high-rise building, but there is no conclusive evidence.
Moat and Stone Walls
Jurakudai was a full-fledged castle surrounded by a moat and stone walls. A wide moat encircled the outer perimeter, and it is believed that techniques such as rough-hewn stonework and fitted stonework were used in the stone walls. Archaeological excavations have confirmed the presence of gold-leafed tiles, parts of the stone walls, and traces of the moat, confirming its grandeur and strength.
About the Name of Jurakudai
Pronunciation of “Jurakudai”
There are two ways to pronounce “Jurakudai”: “Jurakutei” and “Jurakudai.” Historically, both pronunciations have been used, and there is no clear conclusion as to which is correct.
The character “第” originally means “mansion” and is generally pronounced “tei.” However, the pronunciation “dai” has also been used since ancient times, and the usage has varied depending on the region and era. While “Jurakutei” is the most common pronunciation in current academic literature, “Jurakudai” is also widely recognized.
Origin and Meaning of the Name
The name “Juraku” means “to gather enjoyment.” It is believed that Hideyoshi named it this way, expressing his wish to enjoy a peaceful era after achieving the unification of Japan.
Furthermore, the word “Juraku” likely also carried a political connotation of gathering feudal lords for entertainment. In fact, banquets frequently held at Jurakudai, inviting various daimyo, served as a venue to showcase Hideyoshi’s authority.
Alternative Names
Jurakudai is sometimes also called “Jurakutei” or “Jurakujo.” “Jurakutei” is a name that emphasizes its character as a residence, while “Jurakujo” is a name that emphasizes its aspect as a castle. These multiple names indicate that Jurakudai possessed characteristics of both a residence and a castle.
Remains of Jurakudai
Because Jurakudai was thoroughly demolished, very few remains exist at the site. However, several buildings believed to have been relocated during the demolition still exist, conveying the grandeur of Jurakudai to this day.
Daitoku-ji Temple’s Karamon Gate (National Treasure)
The Karamon gate at Daitoku-ji Temple in Kita-ku, Kyoto City, is said to have been relocated from Jurakudai. It is a four-legged gate with a cypress bark roof, adorned with magnificent carvings and decorations, and is a valuable relic that conveys the architectural style of the Momoyama period. It is designated a National Treasure.
However, there is no conclusive evidence that this Karamon gate was actually relocated from Jurakudai Palace, and it remains in the realm of legend. Nevertheless, its style and the splendor of its decorations suggest a high probability that it was relocated from a building of the same caliber as Jurakudai.
Nishi Honganji Hiyun-kaku (National Treasure)
There is also a theory that the Hiyun-kaku, located within the grounds of Nishi Honganji Temple (Honganji), was relocated from Jurakudai Palace. It is a three-story pavilion and is considered one of Kyoto’s three most famous pavilions, alongside Kinkaku-ji and Ginkaku-ji.
However, there is no conclusive evidence that the Hiyun-kaku was also relocated, and some theories suggest that its stylistic characteristics indicate it was built in a later period than Jurakudai. Even so, it remains a valuable structure that conveys the lavish architectural style of the Momoyama period.
Other Legends
There are also legends that the main gate of Myokaku-ji Temple, the gate of Myoren-ji Temple, and the front gate of Honpo-ji Temple are remnants of Jurakudai Palace, but there is no conclusive evidence for any of these. It is also said that some of the stone walls and foundation stones were reused in Nijo Castle and Fushimi Castle, but this remains in the realm of legend.
Current Status and Traces of Jurakudai
Local Conditions
Currently, the site where Jurakudai once stood is an urban area in Kamigyo Ward, Kyoto City, lined with houses and shops. Almost no remains of Jurakudai remain on the surface; only a few stone monuments and explanatory signs remain.
A stone monument marking the “Site of Jurakudai” has been erected in what is believed to be the central part of Jurakudai. Furthermore, many surrounding town names still bear the name “Juraku,” conveying to the present day that a magnificent castle once stood on this site.
Traces Remaining in Place Names
After the demolition of Jurakudai, the site was laid out and became an urban area, but the name “Juraku” remained in many place names. Place names related to Jurakudai, such as Jurakumawari, Jurakumachi, and Izumimachi, are still in use today.
These place names provide clues to estimating the extent of Jurakudai, and the name “Jurakumawari” is thought to refer to the area around the outer moat.
Results of Archaeological Excavations
Several archaeological excavations have been conducted at the Jurakudai site. However, large-scale excavations are difficult due to the current densely populated urban area.
Nevertheless, small-scale excavations have uncovered gold-leaf tiles, parts of stone walls, traces of moats, and foundation stones, confirming the existence and grandeur of Jurakudai. The discovery of gold-leaf tiles, in particular, is important evidence that Jurakudai was a magnificent building comparable to Osaka Castle.
Stone Monuments and Information Boards
Stone monuments and information boards have been erected at various locations within the Jurakudai site by Kyoto City and local volunteers. These sites indicate the extent and history of Jurakudai Palace and are popular destinations for castle enthusiasts and history buffs.
Major stone monuments include the “Jurakudai Palace Site” monument (Kamigyo Ward), the “Jurakudai Palace Main Enclosure Site” monument, and the “Jurakudai Palace Moat Site” monument. Visiting these sites allows you to truly appreciate the scale of Jurakudai Palace in its heyday.
Materials for Understanding Jurakudai Palace
Pictorial Materials
The most important material for understanding the appearance of Jurakudai Palace is the “Jurakudai Palace Folding Screen.” This is a folding screen painting depicting the entire view of Jurakudai Palace, and several versions exist. The most famous is the “Jurakudai Palace Folding Screen” housed in the Mitsui Memorial Museum, which is a valuable resource for understanding the layout and structure of Jurakudai Palace’s buildings.
However, these folding screen paintings are not necessarily accurate measured drawings and may contain artistic exaggerations or omissions. Nevertheless, these documents are indispensable for visually understanding the overall structure of Jurakudai.
Documentary Materials
Records concerning Jurakudai are scattered throughout the diaries of court nobles and missionary reports of the time. In particular, the “Juraku Gyoko-ki,” which records Emperor Go-Yōzei’s visit, is an important historical source for understanding the grandeur and scale of Jurakudai.
Furthermore, descriptions of the construction and events of Jurakudai can be found in court noble diaries such as the “Inotsune-kyōki” and the “Kanemi-kyōki.” These documents allow us to understand the construction process and usage of Jurakudai.
Archaeological Materials
Archaeological materials unearthed during excavations, such as gold-leafed tiles, stone walls, and foundation stones, are also important. The gold-leafed tiles, in particular, are direct evidence of Jurakudai’s grandeur, and their manufacturing techniques and decorations reveal the high level of architectural technology of the time.
The Kyoto City Archaeological Museum and the Kyoto City Archaeological Research Institute display artifacts excavated from the Jurakudai site, allowing visitors to see the actual objects.
Jurakudai and Toyotomi Hideyoshi’s Power
Character as a Regent’s Residence
Jurakudai was not merely a castle, but strongly functioned as the official residence of the Regent (Kanpaku). Hideyoshi aimed to reach the pinnacle of both the samurai and court nobility by assuming the highest position in the imperial court as Regent. Jurakudai was a building that visually represented that authority.
The acceptance of Emperor Go-Yōzei’s visit was a symbolic event demonstrating that Hideyoshi’s power encompassed even the authority of the Emperor. Powerful daimyo from across the country, including Tokugawa Ieyasu, attended this visit, witnessing Hideyoshi’s power firsthand.
Function as a Political Center
Jurakudai was used for political affairs and diplomacy. Jurakudai served as a stage for important political activities, including meetings with various daimyo (feudal lords), negotiations with the imperial court, and receptions with foreign envoys. In particular, during Emperor Go-Yōzei’s visit in 1588, daimyo from across the country gathered to pledge their loyalty to Hideyoshi.
Furthermore, cultural events such as tea ceremonies and Noh performances were frequently held at Jurakudai, showcasing Hideyoshi’s cultural refinement. Tea masters such as Sen no Rikyū and painters such as Kano Eitoku frequented Jurakudai, which also played a central role in Momoyama culture.
Comparison of Jurakudai with Other Castles
Relationship with Osaka Castle
Hideyoshi had two bases: Jurakudai and Osaka Castle. While Osaka Castle was a military and economic center, Jurakudai was more political and ceremonial.
Construction of Osaka Castle began in 1583 and was completed before Jurakudai Palace. Hideyoshi used Osaka Castle as his base while constructing Jurakudai Palace for his political activities in Kyoto.
Relationship with Nijo Castle
After the demolition of Jurakudai Palace, Hideyoshi developed Nijo Castle as his base in Kyoto. However, this Nijo Castle was the “Toyotomi Family Nijo Castle,” located in a different place from the current Nijo Castle built by Tokugawa Ieyasu.
It is believed that some of the materials from the demolished Jurakudai Palace were reused in the construction of this Nijo Castle. However, the Toyotomi Family Nijo Castle was also abandoned after Hideyoshi’s death, and the current Nijo Castle (Tokugawa Family Nijo Castle) was newly built by Tokugawa Ieyasu in 1603.
Relationship with Myokenji Castle
Before constructing Jurakudai, Hideyoshi used Myokenji Castle (Myokakuji Castle) as his base in Kyoto. Built around 1583, this castle was a simple fortress constructed within and around the grounds of Myokenji Temple.
After becoming regent, Hideyoshi needed a more magnificent residence and began construction of Jurakudai. Myokenji Castle was abandoned after the completion of Jurakudai, and Myokenji Temple returned to its original location.
Kyoto after the Demolition of Jurakudai
Construction of the Odoi
Around the time of the demolition of Jurakudai, Hideyoshi began construction of the Odoi, an earthen embankment surrounding the city of Kyoto. Construction of the Odoi, which began in 1591, was a large-scale civil engineering project aimed at defending Kyoto and controlling flooding of the Kamo River.
The total length of the Odoi (earthen rampart) was approximately 22.5 kilometers, and it was built to surround the city of Kyoto. Even today, remnants of the Odoi remain in various parts of Kyoto City and are designated as national historic sites.
Shift of the Center of Gravity to Fushimi Castle
After handing over Jurakudai to Hideyoshi’s nephew, Hidetsugu, Hideyoshi devoted himself to the construction of Fushimi Castle. Fushimi Castle became Hideyoshi’s residence in his later years and served as the center of command for the Korean campaigns and the administration of state affairs.
Hideyoshi died at Fushimi Castle in 1598, and the center of the Toyotomi regime shifted to Osaka Castle. While Nijo Castle, mentioned earlier, was used as the Toyotomi family’s base in Kyoto, it did not possess the same scale or grandeur as Jurakudai.
Current Status and Challenges of Jurakudai Research
Research Progress
Research on Jurakudai is progressing through multifaceted approaches, including archaeology, architectural history, and documentary history. Recent archaeological excavations are yielding new insights into the extent and structure of Jurakudai Palace.
In particular, analysis of the locations where gold-leaf roof tiles have been unearthed has made it possible to make more specific estimations about the location of the main keep and the building layout. Detailed analysis of pictorial materials such as the “Jurakudai Palace Folding Screen” is also progressing.
Unresolved Issues
On the other hand, many mysteries remain about Jurakudai Palace. Many basic details, such as the presence or absence of a keep, the exact building layout, and the detailed circumstances of its demolition, remain undetermined.
The biggest challenge is that large-scale excavations are difficult because the site is located in a densely populated urban area. It is important to conduct excavations and accumulate data by taking advantage of opportunities such as redevelopment projects in the future.
Preservation and Utilization
The preservation and utilization of the Jurakudai Palace site are also challenges. Because very few remains survive, preserving it as a historical site is difficult. However, efforts are needed to convey the history of Jurakudai through various methods, such as the construction of stone monuments and information boards, and restoration using digital technology.
Kyoto City is working to preserve the historical landscape of Kamigyo Ward, including the Jurakudai site, and it is hoped that it will be utilized as a local historical resource.
Cultural Influence of Jurakudai
Symbol of Momoyama Culture
Jurakudai was one of the representative buildings of Momoyama culture. It was a culmination of the highest level of art of the time, with luxurious gold leaf decorations, screen paintings by the Kano school, and a tea room by Sen no Rikyu.
Although it disappeared after only eight years, the cultural activities that took place at Jurakudai had a significant impact on subsequent Japanese culture. In particular, tea ceremonies held at Jurakudai played an important role in the development of tea ceremony culture.
Influence on Castle Architecture
The architectural style of Jurakudai also influenced subsequent castle architecture. The architectural techniques employed at Jurakudai, such as the use of gold-leaf tiles, lavish decorations, and the fusion of residence and castle elements, were later adopted by Osaka Castle, Fushimi Castle, and even castles of the Edo period.
Impact on the Local Community
The construction and demolition of Jurakudai also influenced the urban structure of Kyoto. The town layout of the Jurakudai site forms the basis of the current street configuration of Kamigyo Ward, and traces of it remain in place names.
Furthermore, legends and stories related to Jurakudai have become part of the region’s historical identity and are still passed down among local residents today.
Summary
Jurakudai was a magnificent castle-like residence symbolizing the peak of Toyotomi Hideyoshi’s power. Because it existed for only a short period of eight years, its full extent remains shrouded in mystery, but its scale and grandeur are gradually being revealed through surviving documents and archaeological excavations.
Completed in 1587 and demolished in 1595, Jurakudai Palace is a historical witness to Hideyoshi’s unification of Japan, the glory of the Toyotomi regime, and the tragedy of the Hidetsugu Incident. Although now part of the city, with almost no traces remaining on the surface, place names, stone monuments, and buildings believed to have been relocated still convey its former glory.
Research into Jurakudai Palace will continue, and it is hoped that new discoveries will reveal its full scope. When visiting Kyoto, why not visit the stone monument marking the site of Jurakudai Palace and reflect on this legendary castle?
