Inuyama Castle & Castle Town: National Treasure Day Trip from Nagoya

Why Inuyama: One of Japan's Five National Treasure Castles

Japan has hundreds of castles, but only 12 retain their original wooden keeps from the pre-modern era. Of those 12, just five hold the highest designation: National Treasure. Inuyama Castle (犬山城) is one of them, alongside Himeji, Matsumoto, Hikone, and Matsue.

What makes Inuyama stand out is how it pairs that historical weight with a genuinely enjoyable half-day visit. The castle sits on a bluff above the Kiso River (木曽川), and below it stretches Honmachi Street (本町通り) — a revitalized castle town lined with food stalls, craft shops, and traditional wooden buildings. You get one of Japan's most important castles and one of its most charming small-town eating streets in a single visit, all within 30 minutes of Nagoya.

Inuyama is one of the highlights in our Aichi city guide.

Inuyama Castle: Climbing the Original Keep

History: From 1537 to National Treasure

According to the official Inuyama Castle website, the castle was constructed in 1537 by Oda Nobuyasu, uncle of the famous warlord Oda Nobunaga. It changed hands multiple times during the feudal era before ending up with the Naruse clan, who held it for over 300 years.

What is unusual about Inuyama is that it remained privately owned by the Naruse family until 2004, when ownership transferred to the foundation Inuyamajo Hakutei Bunko. This makes it one of the few castles in Japan that was managed by a single family across centuries. It was designated a National Treasure in 1952 under the Cultural Properties Protection Law.

Inside the Keep: Steep Stairs and Panoramic Views

The castle keep is compact but authentic. The original wooden staircases are steep — nearly ladder-like in places — and there are no elevators. Grip the rope railings and take your time. Visitors who have difficulty with stairs should be aware that this is not an accessible castle.

At the top floor, the open-air viewing platform offers panoramic views of the Kiso River, the surrounding mountains, and the town below. On clear days the view stretches toward Gifu Prefecture. The entire castle visit takes roughly 30-60 minutes depending on crowds.

Admission is ¥550 (~$3.70) for adults and ¥300 (~$2) for children (2024 prices; check the official site for current rates). Hours are 9:00 to 17:00, with last entry at 16:30. No reservation is needed. Visiting in the morning is recommended to avoid lines on the steep interior staircases.

Honmachi Castle Town: Food Stalls and Edo-Period Streets

The walk between Inuyama Station and the castle passes through Honmachi Street, the revitalized castle town (城下町, jokamachi). This is where Inuyama shifts from being a castle visit to being a genuinely fun outing.

The street is lined with machiya-style wooden buildings converted into food stalls, cafes, and craft shops. The atmosphere is distinctly Edo-period, but the offerings are modern and visitor-friendly. Expect grilled rice crackers, dango, soft-serve variations, local sake tastings, and mitarashi dango — the sticky, sweet soy-glazed rice dumplings that are a regional favorite.

Many visitors on Reddit recommend allocating 1-1.5 hours for Honmachi Street, browsing the shops and eating your way down the road. The street is most lively around lunchtime on weekends. On weekdays, it is quieter but most shops remain open.

The key mistake to avoid is visiting only the castle and skipping the castle town. The combination of both is what makes Inuyama worth the trip.

Kiso River: Views and Cormorant Fishing

The Kiso River runs directly below the castle bluff, and walking along the riverbank provides some of the most photogenic angles of Inuyama Castle — the white keep perched above the flowing water with forested hills behind it.

From May 11 to October 15, the river hosts ukai (鵜飼) — traditional cormorant fishing. This is an evening event where trained cormorants catch sweetfish (ayu) from lit boats on the river. The practice dates back over 1,300 years and is recognized as an intangible folk cultural property. Watching from the riverside is free, but boat tours that take you closer to the action are available for a fee.

If you are visiting during ukai season, consider timing your trip to stay into the evening. The combination of the castle, castle town food stalls for lunch, and cormorant fishing at dusk makes for a memorable full day.

Seasonal Highlights: Festivals, Cherry Blossoms, and Ukai

Season	Highlight	Notes
Early April	Cherry blossoms	Castle grounds and Kiso River banks; photogenic combination with the keep
April 5-7	Inuyama Festival	Elaborate floats (yama) paraded through castle town; one of Tokai region's biggest festivals
May-Oct	Ukai cormorant fishing	Evening event on the Kiso River; boat tours available
Autumn	Fall foliage	Kiso River valley colors; fewer crowds than spring
Winter	Quietest season	Castle and town still accessible; some food stalls may close early

The Inuyama Festival (犬山祭), traditionally held April 5-7, is the standout seasonal event. Tall, ornate floats are pulled through the castle town streets during the day, and in the evening they are illuminated with hundreds of paper lanterns. Exact 2026 dates may vary — check the local tourism site before planning around the festival.

Cherry blossom season (late March to early April) is also popular. The castle grounds are a hanami spot, and the view of blossoms with the castle keep and river makes for striking photographs.

Getting to Inuyama from Nagoya

Meitetsu Inuyama Line from Nagoya

The simplest route is the Meitetsu Inuyama Line from Meitetsu Nagoya Station. The ride takes approximately 25-30 minutes and costs ¥570 (~$3.80) one way. Trains run frequently throughout the day. Note that this is a Meitetsu (private railway) line, not JR — it is not covered by the JR Pass.

For those driving, the trip takes approximately 40 minutes from Nagoya via Route 41. Parking is available near the castle town.

If you are planning other things to do in Nagoya or staying near Nagoya Station, Inuyama fits naturally as a morning or afternoon trip. For a broader Inuyama planning guide including what else to combine, see our Inuyama visit guide.
