The area of Togitsu was part of ancient Hizen Province. During the Edo Period, the area was under the control of Ōmura Domain, and its port was a shortcut on the route to the port of Nagasaki, and was thus used by many shogunate officials and daimyo. After the Meiji restoration, the village of Togitsu was established with the creation of the modern municipalities system on April 1, 1889. Togitsu was raised to town status on December 1, 1951.

Togitsu has a mayor-council form of government with a directly elected mayor and a unicameral town council of 16 members. Togitsu, collectively with the town of Nagayo, contributes two members to the Nagasaki Prefectural Assembly. In terms of national politics, the town is part of the Nagasaki 2nd district of the lower house of the Diet of Japan.

Togitsu is unusual in Nagasaki in that it is more active in industry and commerce than agriculture and fishing. It is home to Mitsubishi Electric's Nagasaki Works, which is the major employer. Due it its location, a large number of residents commute to Nagasaki for work.
