Dating from 1611, picturesque Matsue-jō has a wooden interior showcasing treasures belonging to the Matsudaira clan. Known as Plover Castle for the graceful shape of its gable ornaments, Matsue-jō is one of only 12 original keeps left in Japan, making it well worth having a look inside. There are dioramas of the city, as well as displays of armoury, including a collection of helmets – the design of each helmet is said to have reflected the personality of its wearer.

From the top of the castle there are great unobstructed views. It's also pleasant to walk around the castle grounds (free entry) and along the surrounding moat, with its charming bridges and pines reaching out across the water. A good way to see the castle area is via a trip on a Horikawa Sightseeing Boat.
