History of Yoshino Castle: From the Genkō War to a Southern Court Base
The Genkō War and the Uprising of Prince Moriyoshi (1332)
The history of Yoshino Castle begins in Genkō 2 (1332) when Prince Moriyoshi fled to Yoshinoyama and raised an army from this base.
Prince Moriyoshi was a son of Emperor Go-Daigo and one of the central figures in the movement to overthrow the Kamakura Shogunate. Finding it difficult to continue his activities in Kyoto, Prince Moriyoshi fled to Mount Yoshino and fortified the Zaōdō Hall of Kinpusen-ji Temple, establishing it as his headquarters.
Construction and Defense of Yoshino Castle
Prince Moriyoshi made maximum use of the terrain of Mount Yoshino, constructing the following defensive facilities:
- Fortification of Zaōdō Hall: Establishment of the headquarters centered around the Zaōdō Hall of Kinpusen-ji Temple
- Construction of Dry Moats: Excavation of dry moats along the mountain ridges and valleys
- Arrangement of Enclosures: Establishment of defensive positions at various locations on Mount Yoshino
- Establishment of Watchtowers: Observation posts to detect approaching enemies early
The Battle of Yoshino Castle in 1333
In 1333, the Kamakura Shogunate dispatched a large army to capture Yoshino Castle. The *Taiheiki* (Chronicle of Great Peace) details this fierce battle.
Attack by the Shogunate Army
The Shogunate army mobilized tens of thousands of troops and besieged Mount Yoshino. However, the rugged terrain and the tenacious resistance of Prince Moriyoshi’s army made the capture extremely difficult.
The Fall of the Castle and its Aftermath
After fierce fighting, Yoshino Castle finally fell. Prince Moriyoshi successfully escaped and continued his anti-Shogunate movement, fighting in various locations. This resistance at Yoshino Castle had a significant impact on anti-Shogunate forces throughout the country, eventually leading to the downfall of the Kamakura Shogunate.
Yoshino as a Southern Court Base (1336-)
With the collapse of the Kenmu Restoration and the beginning of the Nanboku-cho period, Mount Yoshino reappeared on the historical stage as a Southern Court base.
Emperor Go-Daigo’s Imperial Palace in Yoshino
In 1336 (Engen 1), Emperor Go-Daigo fled Kyoto and established the Southern Court in Yoshino. An imperial palace (angu) was built on Mount Yoshino, which served as the center of the Southern Court for approximately 60 years.
Kō no Moronao’s Attack on the Yoshino Imperial Palace (1348)
In 1348 (Jōwa 4), Kō no Moronao, a general of the Northern Court, led a large army to attack Yoshino. While the palace was temporarily occupied, the Southern Court forces recaptured Yoshino and maintained its function as a base.
Yoshino Castle After the Unification of the Northern and Southern Courts
After the unification of the Northern and Southern Courts in 1392 (Meitoku 3), Yoshino Castle ceased to function as a military base. Subsequently, Mount Yoshino developed as a religious site and a famous cherry blossom viewing spot.
Remains and Highlights of Yoshino Castle
Existing Remains
Although many remains of Yoshino Castle have been lost over the long years since its abandonment, the following traces can still be seen today.
Traces of Dry Moats
Traces of the former dry moats remain in various places on Mount Yoshino. In particular, clear traces of trenches can be seen around Zaōdō Hall and along the ridges of Mount Yoshino. These are thought to be defensive structures constructed during the Genkō War.
Remains of Enclosures
On the flat areas of Mount Yoshino, topography remains that are presumed to be the remains of former enclosures (kuruwa). The topography suggests that multiple defensive positions were arranged around Zaōdō Hall.
