Karatsu Castle: Maizuru Castle with Views of Niji no Matsubara and Karatsu Coastal Beauty

Karatsu Castle — A White Castle Overlooking Karatsu Bay

Karatsu Castle in Karatsu City, Saga Prefecture, is a graceful castle also called Maizuru Castle for its elegant form. It is said to have been completed in 1608 by Terazawa Hirotaka, a retainer of Toyotomi Hideyoshi, and stands atop Mitsurushi Hill jutting into Karatsu Bay. Its great appeal is a superb location commanding views of Niji no Matsubara, Karatsu Bay, and the Genkai Sea.

Spectacular Views From the Keep

The present five-tiered keep was built in 1966, and from its top floor you can take in Niji no Matsubara arcing along Karatsu Bay, the city of Karatsu, and the blue water of the Genkai Sea. The black pine grove of Niji no Matsubara runs about 4.5 kilometers and is one of Japan's three great pine groves. This scenery, resembling a crane spreading its wings, is said to be the origin of the castle's other name, Maizuru. At dusk especially, the pines, sea, and setting sun weave a breathtaking scene.

Exhibits Inside and the Wisteria

Inside the keep are displays on the history of the Karatsu domain, materials connected to the Terazawa family, fine works of Karatsu ware, and models of the Karatsu Kunchi festival floats. Maizuru Park, where the castle stands, is also known for cherry blossoms and wisteria, with the wisteria usually at its best around late April. The purple clusters coloring the castle-hill slope are a springtime highlight.

Karatsu Kunchi

At Karatsu Shrine below the castle, the autumn grand festival Karatsu Kunchi is held grandly each year from November 2 to 4. In this spirited festival, 14 gorgeous floats shaped like sea bream, helmets, and dragons parade through the castle town to festival music, and it is inscribed on the UNESCO list of Intangible Cultural Heritage.

Practical Travel Notes

• Best season and time: Spring when the wisteria blooms and November for the Karatsu Kunchi are especially recommended; dusk offers a superb scene of pines, sea, and sunset
• Time needed: About an hour to tour the keep and enjoy the views; roughly half a day including a walk in Maizuru Park and nearby Karatsu Shrine

One Piece of Advice

The hilltop keep can be windy on some days, so a light jacket is reassuring. During the Karatsu Kunchi the castle town is very lively and parking crowded, so public transport is recommended. Since Niji no Matsubara and Yobuko are easiest to reach by car, planning to tour the Karatsu area together works well.
