Inuyama Castle
Japan's Oldest Castle Keep Commanding the Kiso River
Inuyama Castle's main keep was constructed in 1537 by Oda Nobuyasu, uncle of the famous warlord Oda Nobunaga, during Japan's Warring States period. The castle occupies a strategic position atop a 40-meter bluff overlooking the Kiso River, which served as a natural moat and transportation route. The location allowed control over the river crossing and surrounding plains, making it militarily significant.
The castle's main keep is recognized as Japan's oldest surviving original castle structure, predating even Himeji Castle's current keep. Unlike most Japanese castles that were destroyed and reconstructed, Inuyama's keep has stood continuously for nearly 500 years, surviving wars, earthquakes, and fires. In 1965, it was designated one of only five National Treasure castles in Japan, alongside Himeji, Hikone, Matsumoto, and Matsue.
Unique among Japanese castles, Inuyama was privately owned by the Naruse family from 1618 until 2004, when ownership transferred to a foundation. The castle exemplifies the compact, functional design of early castle architecture - just three stories externally (four floors internally) with steep stairs and a top-floor observation deck offering 360-degree views. The simple elegance and intimate scale allow visitors to truly understand how feudal lords lived and defended their domains.

Tips & Visiting Guide
Make the most of your visit with these helpful tips and guidelines.
Prepare for Steep Stairs
The castle interior features extremely steep wooden stairs (close to 60 degrees) connecting the four floors. Wear appropriate footwear with good grip. Not suitable for those with mobility issues. Climbing to the top is required - there's no elevator.
Top Floor Observation Deck
The fourth floor observation deck offers 360-degree views of the Kiso River, surrounding mountains, and countryside. On clear days, see Nagoya's skyscrapers in the distance. The outdoor deck has low railings - hold tightly, especially on windy days.
Visit Early or Late
The small castle becomes crowded quickly, especially on weekends and holidays. Arriving at opening time (9:00) or late afternoon offers shorter wait times. The compact interior can feel cramped when busy.
Cherry Blossom Season
Early April brings cherry blossoms around the castle grounds and along the riverbank. The combination of white castle, pink blossoms, and river creates stunning views. Expect large crowds during this period.
Explore the Castle Town
The approach streets feature preserved merchant houses, traditional shops, cafes, and restaurants. The area retains Edo-period atmosphere. Try local specialties like dango (rice dumplings) and traditional sweets.
Riverside Dining
Restaurants along the Kiso River offer views of the castle from below. River fish dishes and traditional Japanese cuisine are specialties. The riverbank park is perfect for picnics with castle views.
Cormorant Fishing Season
From June to September, traditional ukai (cormorant fishing) demonstrations occur on the Kiso River at night. This ancient fishing technique using trained cormorants creates an atmospheric scene with the castle illuminated above.
National Treasure Status
Inuyama is one of only five National Treasure castles. This designation recognizes its historical authenticity, architectural significance, and preservation. Understanding this rarity enhances appreciation of what you're experiencing.
FAQ
How long does it take to visit Inuyama Castle?
The castle itself takes 30-45 minutes to explore, but allow 2 hours total including the climb up, queuing, and exploring the town below. The castle town deserves another 1-2 hours.
Are the stairs steep?
Yes, extremely steep! The original wooden stairs are almost ladder-like. Not suitable for those with mobility issues. Wear comfortable shoes and use handrails. Going down is scarier than up.
Is this an original castle?
Yes! One of only 12 original castle keeps in Japan and the oldest, dating from 1537. The authentic architecture and atmosphere make it special compared to reconstructed castles.
Can I see cormorant fishing?
Yes, from June to October on the Kiso River below the castle. Evening boat tours offer dinner while watching this 1,300-year-old fishing tradition. Advance booking recommended.
Is the view from the top worth it?
Absolutely! 360-degree views over the Kiso River, Gifu Castle, and on clear days, the Japan Alps. The wooden balcony surrounds the entire top floor. Slightly scary but spectacular.
What's in the castle town?
Traditional shops, cafes, and the interesting Karakuri puppet museum. Try the local dengaku (grilled tofu with miso). The preserved streets offer good photo opportunities.
Are there English explanations?
Basic English signage exists but is limited. Consider downloading a translation app or hiring a guide for deeper understanding. The ticket office has English pamphlets.
When is it least crowded?
Weekday mornings are best. Avoid weekends, holidays, and cherry blossom season when queues can exceed an hour. Winter is cold but peaceful with possible snow views.
Is photography allowed inside?
Yes, photography is permitted throughout the castle. The narrow stairs and windows make some shots challenging. The top floor balcony offers the best photo opportunities.
How do I get there from Nagoya?
