Ako: Castle of the 47 Samurai

Impressive ruins in Ako City, Hyogo Prefecture

It took 13 years before the castle was completed in 1648.

Originally there were twelve gates and ten turrets.

Although no longer beside the sea, in the past boats could set sail from docks located within the grounds of the castle.

The walls are angled sharply like Goryokaku in Hakodate.

The castle grounds are open from 9am to 4:30pm.

A donjon (keep) was not built as permission was never obtained from the Tokugawa shogunate.

Entrance to the park, and what remains of the castle, is free.

Be sure to visit the nearby historical museum and Oishi Shrine.

It was easy to get the feel of the size, and some of the layout, of the original castle from these reconstructed raised 'room' platforms.

What remains of the castle now sits inside a lovely public park.

Built on an expansive flat area originally beside the sea, Ako Castle was completed in 1648. It was home to the feudal lord, Naganori Asano, whose death was avenged by 47 of his samurai - one of Japan's most famous stories. Although a donjon (keep) was never built, many stone walls remain and other buildings have been reconstructed. The area is now a beautiful park, especially during cherry blossom season.

This castle looks so peaceful and I can't imagine that samurais in that area were boiling over their lord's disgrace and determined a vengeance on the enemy.

Wow. Chushingura is a Edo based incident, it never occurred to me that the Asano Castle was is another place! I love the variations of this story. Would be great to visit the castle that inspired such loyalty!
