Karatsu, like many other municipalities in Japan, is actually the result of a merger of smaller towns and villages from the surrounding area, which occurred in 2005. Genkai was the lone holdout of this merger, owing to its nuclear power plant. Karatsu, formed from the Japanese word roots 唐 kara (China, or continental East Asia in general), and 津 tsu (port), signifies its historical importance as an ancient trading port between Japan with China and Korea.
In addition to Standard Japanese, the local dialect (Karatsu-ben) is also understood by most. It is actually a bit closer to the Hakata dialect than that of the rest of Saga prefecture, but Saga-ben is also understood.
Korean language signage exists, but sparsely.
Saga prefecture's own airport is located south of Saga City, and as a result is much less convenient to Karatsu than the international airport in Fukuoka.
From Fukuoka International Airport, take the Fukuoka City Subway Airport Line to its terminus, Meinohama, and transfer to the JR Chikuhi Line. Travel time from Hataka is ~84 minutes (~68 minutes if you catch a Rapid Chikuhi Line train (not labelled as such; departs Meinohama at 09:47, 10:47, 17:51, and 18:50)). Some trains will run all the way from the airport to Nishi-Karatsu station without requiring transfers.
The Oteguchi Bus Terminal is the main bus hub in Karatsu. It's less than a ten minute walk from Karatsu Station (take the north exit and walk straight, turn right at the T-intersection in front of city hall.
Karatsu is also serviced by a ferry, which links it to Iki island in Nagasaki prefecture. From there, it's possible to catch another ferry onward to Busan, Korea by way of Tsushima, also part of Nagasaki. The ferry terminal is in Oshima, roughly a 20-minute walk from Nishi Karatsu Station . Busses also run to the ferry terminal.
For the most part, trains aren't a viable way to see most of Karatsu, busses are a better bet. The best way, however, is under your own power: basic bicycles are available for hire at Arupino (white building with a blue dolphin on it next to Karatsu Station), and cars can also be rented from several locations.
For car rentals, the tourist information center at Karatsu station seems to have better rates than the Toyota place down the street; a yellow-plate car (seats 4) rents for about ¥6800/day, with an additional ¥1050 for insurance. At least one of the employees speaks pretty good English.
- 1 Karatsu Castle (唐津城). A 1966 reconstruction of the former castle.
- 2 Niji no Matsubara (虹の松原). This pine forest was planted by the feudal lord Terasawa as a counter-measure against the strong winds and tides in Karatsu Bay. It stretches for 4 km along the coast and is one of Karatsu's most well-known tourist attractions. It's possible to access by bicycle from central Karatsu, but take care when riding on the road, especially at night.
- 3 Nanatsu-Gama (七ツ釜). Also in Minato is this group of seven caves, formed by the tumultuous Genkai Sea. Accessible by bus, with a bit of a walk from the main road.
- 4 Tategami-Iwa (立神岩). Located in the town of Minato, a scenic group of standing rocks along the coast. Can be accessed by bus.
- 5 Nagoya Castle Ruins (名護屋城). Not to be confused with Nagoya Castle in Nagoya, this castle was the launching point for invasions of Korea during the Sengoku Period. Today the castle walls are all that remain. It's still pretty nice, and there's a modern museum on-site.
- 6 Takashima (高島). Not to be confused with the nearby Takashima (鷹島) in Nagasaki prefecture, this island in Karatsu Bay is dominated by a large hill, and is accessible by a ferry that leaves from the jetty near Karatsu Castle. There's a small village on the island with some picturesque little garden plots, as well as a shrine thought to bring luck in winning the lottery. It's possible to climb the hill to its summit via a well-marked and not terribly strenuous path, which offers nice views of Karatsu and its surroundings on a clear day. It's no longer possible to walk or bike all the way around the island, as a significant section of the road was blocked off due to a landslide. Interestingly, most villagers on the island have the surname of "Nozaki". Bicycles can be brought along on the ferry for an additional charge, but the island is walkable without one.
- 7 Udono Sekibutsu Statues (鵜殿石仏群). A cave of stone Buddha carvings. It is said that the famous priest Kukai stopped here after returning from China.

- Karatsu Kunchi Held during November 2-4 each year, this three-day festival is Karatsu's most famous. 14 floats (known as hikiyama in Japanese) are drawn through the city by people from the various neighborhoods.
- Hamasaki Gion Festival In mid-July the city lights up with many floats to celebrate what citizens hope to be a good harvest.
