Inuyama Castle Travel Guide: Japan’s Oldest Surviving Keep

Planning a visit to Inuyama Castle in Aichi? This English guide covers the National Treasure keep above the Kiso River, the castle town, and a repair notice to reconfirm.

Operational details such as opening hours, admission fees, and train times can change. Prefer official pages and reconfirm before you travel (sources checked on 22 October 2026).

Why visit

  • Inuyama Castle stands on a hill at the edge of the Nobi plain, with the Kiso River below the keep.
  • The castle office describes the keep as the oldest one still standing in Japan, and says it is thought to have been built around 1537 by Oda Nobuyasu, an uncle of Oda Nobunaga. It is a National Treasure. This is an original timber keep, not a modern reconstruction.
  • On 6 October 2026 the castle announced partial entry limits while the keep’s railings are repaired. Check that notice before you promise yourself every floor.
  • The city has since dated that work: 4 January to 28 February 2027, on the fourth floor. The tower stays open and no scaffolding goes up outside, but the top floor is divided into a viewing half and a work half, walked one way, so you cannot complete the circuit of the balcony.

The keep

The small wooden tower is the whole point. The top looks over the river and the plain. Entry can be held back when it is crowded, and the repair may close a section. Reconfirm the morning you go.

There are no advance tickets, so a busy weekend can mean a long wait at the foot of the stairs. Shoes come off at the entrance into a bag you carry, and the stairs run from the basement to the top floor without a lift.

Stone base and the slope

You walk up from the town. The approach is short and steep compared with Himeji’s long gates. There is no elevator story here.

Castle town and the river

Old streets sit below the hill. Meiji-mura and the cormorant-fishing season on the river are separate outings. Pick one if the keep has already taken the middle of the day.

Food and drink

  • The town below the castle has cafes and lunch shops. Eat there, not in the tower.
  • Festival days and blossom weekends fill the same few streets. Have a backup if the first room is full.

Getting there and around

  • Meitetsu trains run from Nagoya to Inuyama. The castle office describes the ride as a short one. Confirm the train name and the walk from the station you actually use.
  • Two Meitetsu stations serve it. Inuyama-yuen is about 15 minutes on foot along the river side; Inuyama, on the Nagoya line, is about 20 minutes from the west exit up the main street through the castle town. Arriving at one and leaving from the other avoids retracing the walk.
  • A car is useful only if you are combining the river and an out-of-town museum. The keep itself does not need one.
  • Admission and the last entry change. Read them on the castle site. Do not rely on a blog’s price.

Where to stay

  • Inuyama is a half day from Nagoya.
  • Stay in the castle town if you want the streets after the day visitors leave, or if your train back is late.

Best time to visit

  • The castle describes spring blossom and the Inuyama festival, summer on the river, autumn color, and the occasional snow on the keep.
  • The repair notice matters more than the season. A closed railing changes the visit even on a beautiful day.

Practical tips

  • Read the repair notice, then the entry board.
  • The stairs are steep and the rooms are small. A large bag is a nuisance.
  • Another original National Treasure keep, on a plain instead of a river cliff, is the Matsumoto Castle guide.
  • A third original keep, in Fukui and currently under repair, is the Maruoka Castle travel guide .

Suggested day-trip outline

  1. Train from Nagoya and confirm the repair notice.
  2. Climb the keep if that section is open.
  3. Walk the town or the riverbank, then back.
