If you’re taking the time to visit Kochi Castle, you’ll want to fully enjoy what makes it special.
This article is for first-time visitors, introducing must-see spots and defining features—like the 15 buildings spread across its expansive grounds, and the rare fact that both the castle keep and the Honmaru Palace still survive—along with the best seasons to visit and the key info you need to make the most of your trip.

What is Kochi Castle Like?

Kochi Castle is located in Kochi City, the center of Kochi Prefecture.
It’s a well-known landmark that attracts tourists from across Japan and is counted among Japan’s Top 100 Castles.
It’s one of the 12 castles in Japan with an original keep surviving from the Edo period, and 15 buildings designated as Important Cultural Properties are scattered throughout the grounds.
These structures range widely, from defensive facilities like the Otemon Gate and Kairo-mon Gate to living quarters like the Honmaru Palace.
Each building has plenty to see, offering a glimpse into everyday life and the defensive ingenuity of the time.
Kochi Castle’s biggest draw is the rarity of having both the castle keep and the Honmaru Palace still standing.
In fact, Kochi Castle is the only one in Japan where both the keep and the Honmaru Palace survive.
Kochi Castle was founded by Yamauchi Kazutoyo, the first lord of the Tosa Domain (present-day Kochi Prefecture). Construction began in 1601, and the castle was completed in 1611.
Since then, it has endured hardships such as fires and the castle abolition order, preserving its form to this day.

Make the Most of Kochi Castle’s Unique Features! 5 Must-See Highlights

Selected as one of Japan’s Top 100 Castles, Kochi Castle is a sightseeing spot you can enjoy for a full day, with many historic structures—from defensive facilities like the Otemon Gate and Kairo-mon Gate to the Honmaru Palace.
Here, we’ll narrow it down to five key sights, including the most important structures like the “castle keep” and “Honmaru Palace,” and introduce a curated list of highlights you absolutely shouldn’t miss when visiting Kochi Castle.

1. The “Castle Keep” with Panoramic Views of Kochi City and the Grounds

Kochi Castle’s keep has a four-tier exterior, while the interior is a three-level, six-story structure—an archetypal example of a watchtower-style keep.
It’s one of the 12 castles in Japan with an original keep built in the Edo period still standing.
From the top floor of the keep, you can take in sweeping views of beautiful Kochi City and the castle grounds.
The polished shachihoko roof ornaments on the keep are another highlight.
These mythical creatures were believed to help prevent fires, which is why they were installed.
At night, the keep is illuminated, offering a dreamy view that feels different from daytime.

2. “Kaitokukan (Honmaru Palace),” Where You Can Feel the Aesthetics of the Era

Kaitokukan (Honmaru Palace) stands in the central area of Kochi Castle.
Because Kochi Castle is the only castle in Japan where both the keep and the Honmaru Palace still survive, it holds particularly high historical value even among the 12 castles with original keeps.
Kaitokukan (Honmaru Palace) was used as the place where the lord received guests.
With beautiful decorations and a design that reflects Edo-period samurai culture and architectural styles, its charm lies in the glimpse it offers into the aesthetics of the time.
Another feature is the “shinobigaeshi,” a protective measure designed to prevent intruders.
The fact that this shinobigaeshi is the only one still surviving in Japan can also be considered one of Kochi Castle’s defining features.

3. The Front Gate, “Otemon Gate,” Built to Stop Enemy Intrusion

Kochi Castle’s Otemon Gate is one of the 15 Important Cultural Property buildings, built in 1801.
It’s one of the castle’s key gates and serves as Kochi Castle’s main entrance.
As a defensive feature against enemy attacks, the gate has a double-layered roof and a solid wooden structure that feels imposing.
On the second floor of this turret gate—built by stacking stone walls and placing a turret above—there is an “ishi-otoshi,” used to drop stones or boiling water on enemies attacking from directly below.
It’s also interesting to see architectural features designed for combat, such as the ability to attack intruders from sections of the surrounding wall.

4. The “Karakuri Gate (Tsume Gate)” That Confuses Enemies

The Karakuri Gate (Tsume Gate) is a turret gate that connects the Honmaru Palace and the Ninomaru.
It was built as a staggered, trick-style gate so enemies who have entered the castle can’t pass through easily, with a layout that prevents them from reaching the Honmaru by simply going straight ahead.
The name Tsume Gate comes from the fact that the connecting corridor from the second floor to the Ninomaru was used as offices for senior retainers such as churo and karo.
The Karakuri Gate (Tsume Gate) is one of the 15 surviving buildings designated as Important Cultural Properties.

5. The “Statue of Yamauchi Kazutoyo,” Who Helped Lay the Foundations of Modern Kochi

The bronze statue of Yamauchi Kazutoyo stands 4.32 m tall and weighs 3.6 tons. The pedestal is 5.08 m, making the total height 9.4 m—one of Japan’s largest equestrian statues.
It stands by the Kochi Prefectural Library, just after entering through Kochi Castle’s Otemon Gate.
The statue was created in honor of Yamauchi Kazutoyo, the first lord of the Tosa Domain, who built Kochi Castle and developed the castle town.
The current statue is the second version, recreated and unveiled on September 20, 1996, the anniversary of Yamauchi Kazutoyo’s death, by sculptor Hakuu Motoyama, who also made the Sakamoto Ryoma statue at Katsurahama.

Every year from April to May, and for two months around November 15 (Ryoma’s birthday and the anniversary of his death), a 13-meter viewing platform is set up next to the statue.
This allows you to view the Pacific Ocean from the same eye level as Ryoma.

    I've visited so many Japanese castles, and honestly, they all look pretty similar. If you're not really into Japanese history, it's mostly just a good spot for photos.

    The location is right in the city, so it's very convenient to get to. Kochi Castle is built on a slope, so you'll need to climb some stairs, which can be a bit tiring. The exhibits inside are detailed, and there are Chinese translations, making it easy to understand the significance.

    Kochi Castle is one of the 12 original castle towers among Japan's Top 100 Castles. It's really well preserved. There's an entrance fee only if you go inside the main tower, where you can get a great view of Kochi City. Definitely a must-visit spot in Kochi.
