What Is Ogaki Castle? History and Sekigahara Travel Guide
Where the Sengoku Era and a Castle Town Overlap
Ogaki Castle (Ōgaki-jō) is a flatland castle (hirajiro) in the heart of Ogaki City, Gifu Prefecture, and an easy-to-reach sightseeing spot just a 7-minute walk from JR Ogaki Station.
It is said to have been founded in 1535 by Miyagawa Kichizaemon-no-jō Yasusada, who served the Toki clan, the military governors of Mino, and it later became the base of Ishida Mitsunari of the Western Army during the Battle of Sekigahara in 1600.
Even after the main forces moved to Sekigahara, a fierce battle for control unfolded at Ogaki Castle.
From 1635 in the Edo period, the Toda clan became lords of the 100,000-koku domain (a domain ranked by rice-tax yield) and supported Ogaki's development as a castle town.
For visitors to Japan, it is a spot where you can see a major turning point of the Sengoku period overlaid with the ongoing life of a regional city.
The Four-Story, Four-Tier Keep Rebuilt After the War
The current keep was rebuilt in 1959 after the original was destroyed by fire during the war in 1945.
While carrying on the memory of the keep that was once designated a former National Treasure, it remains beloved as a symbol of the castle town of Ogaki.
Because the keep has a rare four-story, four-tier structure—uncommon nationwide—paying attention to the combination of white walls, layered roofs, and stone walls reveals a three-dimensional presence that photos alone cannot convey.
Be sure to also see the Ushitora Sumi Yagura (northeast corner turret), rebuilt in 1985 at the northeast of the main keep area, as it makes the overall layout of the castle easier to understand.
Top Things to See at Ogaki Castle: Exhibits and the Observation Deck
Exhibits on the Battle of Sekigahara and Ogaki Castle
Inside the keep, you can view exhibits related to the Battle of Sekigahara and Ogaki Castle.
"Sekigahara" is a place name well known in Japanese history, but learning that Ogaki Castle was the base of Ishida Mitsunari of the Western Army brings the history of the surrounding region into sharper relief.
Rather than trying to memorize every detailed name of historical figures, it's easier to understand if you focus on what role this castle played before the Eastern and Western forces clashed.
Since the exhibits are presented with documents, models, and hands-on corners, even travelers with little background knowledge of the Sengoku period can easily follow the flow of events.
Exhibits Touching on the Lives of Samurai and Commoners
Another exhibit presents materials related to the culture and daily life of samurai and commoners.
A castle was not merely a building for warfare—it was also a center of politics and everyday life.
By viewing exhibits on armor (kacchū), tools, and scenes of the castle town, you can imagine the kind of environment in which people lived at the time.
View the Townscape of Ogaki From the Observation Room
The top floor has an observation room.
Looking down over the townscape of Ogaki, you can see how the castle remains naturally preserved within the present-day city.
Gazing at the outside scenery after viewing the exhibits makes the distance between historical events and the town of today feel a little closer.
Strolling Ogaki Park and the Castle Town
Take Time to Admire the Keep From the Outside
Ogaki Castle is best enjoyed by exploring it along with Ogaki Park.
Viewing the keep from a slightly different angle, rather than only from the front, changes how the layered roofs and the texture of the stone walls appear.
Admiring the exterior from the park side before or after touring the interior will make the castle's impression linger longer.
See It Alongside the Scenery of the Seasons
Ogaki Park is a place where you can enjoy the castle together with seasonal flowers and greenery.
In spring, some people visit to see the combination of cherry blossoms and the keep, with the best viewing time typically from late March to early April.
During busy seasons, you can enjoy a pleasant visit by not blocking the paths and yielding your spot to the next person once you've taken your photo.
Photography Etiquette at Ogaki Castle That Visitors to Japan Should Know
Distinguish Between Personal and Commercial Use
When taking photos or videos within Ogaki City's history and culture facilities, photography limited to non-commercial, personal records does not require a permit application.
On the other hand, if you intend to use what you have filmed commercially, or to publish it on video-sharing sites such as YouTube, a prior permit application to the Ogaki City Board of Education is required.
Be aware that holiday snapshots and filming intended for publication, sale, or distribution are treated differently.
Give Priority to On-Site Signage and Staff Guidance
Inside the building, there are some areas and materials that cannot be photographed.
If you're unsure whether photography is allowed, it's safest to check the signage and, if necessary, ask a staff member.
In front of cultural properties and exhibit materials, please be considerate so that flash, tripods, or loud voices during filming do not disturb others' viewing.
