It began in the early 17th century, when Hirotaka Terasawa, the first lord of the Karatsu Domain, planted it as a windbreak and tide-protection forest. Today, around 1 million black pine trees grow in clusters across a stretch Approx. 4.5 km long and Approx. 500 m wide.
It is now counted among Japan’s three great pine groves along with Miho no Matsubara and Kehi no Matsubara.

3. Karatsu Castle
Karatsu Castle was completed over seven years starting in 1602 by Hirotaka Terasawa, the first lord of the Karatsu Domain and a retainer of Toyotomi Hideyoshi.
It is said that various feudal lords from across Kyushu assisted in its construction, and that materials from the dismantling of Nagoya Castle (in Karatsu City) were also used.
The castle is also known as Maizuru Castle because the pine groves stretching east and west from the castle resemble the wings of a crane in flight.

4. Nanatsugama
Nanatsugama is designated as a national Natural Monument.
It is a scenic spot formed over many years as basalt cliffs jutting into the sea were eroded by the rough waves of the Genkai Sea.
The cliffs have been deeply hollowed out, and as the name suggests, seven caves line the shore.
The largest cave opening is 3 m wide and extends 110 m deep, where you can see columnar joints, rock surfaces formed when lava cools and hardens into regularly aligned pillar-like shapes.

5. Hoto Shrine
This shrine stands on Takashima, a remote island floating in Karatsu Bay.
It was built about 450 years ago to enshrine Tsunayoshi Nozaki Okinokami, who drove away pirates that had been attacking Takashima and protected the island.
In the Heisei era, more and more people began visiting to pray for good fortune because of the shrine’s auspicious name, and after several worshippers reportedly won large lottery prizes, it became known nationwide as a shrine that brings lottery luck.

6. Hado Cape
A small cape jutting out from the Higashimatsuura Peninsula, Hado Cape is famous as a spot where you can feel the sea breeze on the grass and take in panoramic views of the Genkai Sea.
It is located within Genkai Quasi-National Park, a national park area spreading across northwestern Kyushu, and offers plenty of activities including hiking, camping, and swimming.
If you cross to the underwater observation tower connected by a pier from Hado Cape, you can look out over the islands of the Genkai Sea from the deck above the water.

7. Yobuko Morning Market
Yobuko has long been known as one of Japan’s leading port towns and once prospered through whaling. The Yobuko Morning Market, which has continued since the Taisho era, has a history of more than 100 years and is counted among Japan’s three great morning markets alongside Wajima in Ishikawa Prefecture and Takayama in Gifu Prefecture.
The sight of nearly 50 stalls lined up along the Approx. 200 m Morning Market Street near Yobuko Port from 7:30 am to 12 pm is truly impressive! Asking for recommended ways to eat the local foods, negotiating prices, and chatting with the vendors are all part of the market’s charm.

8. Saga Prefectural Nagoya Castle Museum
Hizen Nagoya Castle was built as a military base for Toyotomi Hideyoshi’s continental campaigns (the Bunroku and Keicho Wars).
After that, from the outbreak of war in 1592 until the feudal lords withdrew following Hideyoshi’s death, it served as a base for the campaigns on the continent for seven years.
Because the castle ruins and camp ruins together form one of the largest castle site groups in Japan, they have been designated as the Special Historic Site “Nagoya Castle Ruins and Camp Ruins.”
At the museum next to the ruins, visitors can learn about the castle and the history of exchanges between the Japanese archipelago and the Korean Peninsula through a variety of exhibits.

9. Former Takatori Residence
The residence of Takatori Koreyoshi, known as the “coal mining king of Hizen.”
Built in 1905 as his home and guesthouse, it stands on a spacious site of Approx. 2,300 tsubo, with two large buildings: a grand hall wing and a residential wing.
While mainly Japanese in style, the building also incorporates Western-style rooms, reflecting the characteristics of modern Japanese-style architecture of the time. At the same time, in a bold and highly individual touch befitting Koreyoshi, who loved Noh theater, the grand hall includes a wooden Noh stage.
Also well worth seeing are the 72 cedar door paintings depicting 29 types of subjects such as wisteria and wild cherry blossoms, said to have been painted by a Kyoto artist during a stay of about half a year.

Karatsu’s Biggest Festival, “Karatsu Kunchi”
The autumn grand festival of Karatsu Shrine is held over three days, beginning with the Yoiyama evening float procession on November 2, followed by the Shinko procession to the otabisho on November 3, and the final festival on November 4. This historic festival is said to have begun in the Edo period, and the “Karatsu Kunchi Hikiyama Float Event” is registered as a UNESCO Intangible Cultural Heritage and a nationally designated Intangible Folk Cultural Property.
Fourteen magnificent hikiyama floats parade through the old castle town to the sound of flutes and drums and spirited chants of “Enya, Enya” and “Yoisa, Yoisa.” During Yoiyama, the giant floats are illuminated by lanterns, creating a magical atmosphere.
