Hello! I’m SacChi, a blogger based in Kochi.
Today, I’m excited to introduce one of Kochi’s most iconic landmarks—Kochi Castle. Visible from both the tram line and the Otesuji shopping street, its stately presence stands as a true symbol of the city.
🏯 What Is Kochi Castle?
Built by Lord Yamauchi Kazutoyo starting in 1601 and completed around 1611, Kochi Castle is one of the few remaining Japanese castles with an original keep dating back to the Edo period. It has earned a spot among the “Top 100 Japanese Castles.”
While the outer baileys (Ninomaru and Sannomaru) no longer remain, Kochi Castle is the only castle in Japan where the keep, palace, and front gate still stand together—making it a must-visit for history lovers.
🕰 Kochi Castle Timeline
- 1601: Construction begins by Yamauchi Kazutoyo

🔎 Highlights of Kochi Castle
1️⃣ The Keep (One of the Original 12)
A stunning 3-tier, 6-story wooden structure with panoramic views of Kochi City and even the Pacific Ocean from the observation deck.
2️⃣ The Honmaru Palace (Kaitokukan)
This preserved Edo-era palace was once the site of official affairs and now allows visitors to experience samurai-era architecture and culture.
3️⃣ Otemon Gate
The stately main gate of the castle. In spring, cherry blossoms bloom around it, making it one of the most photogenic spots in the city.
4️⃣ Seasonal Views
From cherry blossoms in spring and lush greenery in early summer to vibrant autumn leaves and winter illuminations, the castle offers something to enjoy all year round.
✨ My favorite spot is the engawa (veranda) at Kaitokukan. The breeze flowing through makes me want to lie down and take a nap every time I visit.

💡 Fun Facts You’ll Learn During Your Visit
At the information booth near Otemon Gate, you can join a free guided tour—highly recommended! Here are a few things I learned:
- The Mitsubishi “Three Diamonds” logo has a historic link to Kochi Castle (more on that in Part 2!)
- Kochi Castle has 16 unique stone gutters designed to protect its walls from rainwater—an adaptation to Kochi’s famously rainy climate
- Although never involved in actual battle, the castle has clever defensive features like stone drop windows
- The keep was used as an emergency stronghold—not a living space for the lord
- The shachihoko (roof ornaments) are gendered—open-mouthed for male, closed-mouthed for female
📝 Summary
Kochi Castle is the only castle in Japan that retains its original keep, palace, and front gate. Its historical value, architectural charm, and stunning views make it a top destination—whether it’s your first time in Kochi or a repeat trip.
Stay tuned for Part 2, where I’ll uncover the little-known connection between Kochi Castle and the Mitsubishi logo. Don’t miss it!
