The Saito Production group of manga creators will continue its publication with the assistance of the Big Comic's editorial department.

With a cumulative total of 300 million copies in circulation in various formats, including compilation books, it is one of the best-selling manga series.

Duke Togo has a very quiet personality and will only talk when he needs to, he shows very little to no emotion when carrying out an assassination and is willing to kill anyone who will threaten to expose him.

Golgo 13 also employs many different people himself to assist him in his assassination jobs, such as in providing extra information on his targets to modifying his weapons, vehicles, and gadgets.

It is known that he may be the biological father of many different children all over the world from the many sexual encounters he has had with women throughout the series, such as a four-year-old son named Joey from ex-Provisional Irish Republican Army fighter Catherine McCall.

[6] Early on, Takao Saito developed a system where he created the page layout based on a script written by the editorial department.

[10] Takashi Nagasaki was Saito's editor on the series in the mid-1980s, and later wrote two stories for the manga under the pen name "Keishi Edogawa".

Thompson lists one from 1986 because of complaints from the Iranian embassy in Japan, another from 1988 about money laundering in the Vatican, and one from 1989 about a Hollywood actor blackmailed when someone discovers he has AIDS.

He said he had no idea when Golgo 13 would end, claiming "The manga has continued so long that it is no longer the property of the author; it belongs to the readers.

"[14] Due to difficulties that arose from the restrictions implemented by the government to combat the COVID-19 pandemic in Japan, Golgo 13 began its first hiatus in its 52-year history in May 2020.

The Saito Production group of manga creators continues its publication with the assistance of Big Comic's editorial department.

[19] Written and illustrated by Takao Saito, Golgo 13 has been serialized in the monthly manga magazine Big Comic since its January 1969 issue, published in October 1968.

[20] The chapters have been collected into tankōbon volumes by Shogakukan and Leed Publishing, a spinoff of the author's own Saito Production,[12] since June 21, 1973.

[23] In 1986, Leed Publishing released four Golgo 13 stories translated by Patrick Connolly: "Into the Wolves' Lair", "Galinpero", "The Ice Lake Hit" and "The Ivory Connection".

[12] The Professional was a re-printing of "The Argentine Tiger", a story where Golgo is hired by the British Government to assassinate the reportedly dead ex-president of Argentina Juan Perón.

[29] A third spin-off, G no Idenshi: Shōjo Fanette (Gの遺伝子 少女ファネット), began serialization in the August issue of Big Comic Zōkan on July 15, 2022.

[30] Toei Company produced a live-action film simply titled Golgo 13 in 1973, directed by Junya Sato and starring Ken Takakura as Duke Togo and Pouri Banayi as Catherine Morton.

Golgo 13's voice is provided by Tetsurō Sagawa in the Japanese version, and Gregory Snegoff in Streamline Pictures' English dub.

He cited the timing of when Golgo actually takes his shot as an example; "It evokes iaidō [the martial art of drawing one's sword and mimicking a deadly blow].

[55] Anime News Network's Carl Kimlinger compared Saito's work on the series to the novels of John le Carré and Frederick Forsyth, as the stories are "dark, meticulously constructed [and] painstakingly realistic".

[56] Leo Lewis of the Financial Times wrote that "Unsmiling, misogynist and inexorable, [the character] is a literary cousin of James Bond without the scene-softeners of Moneypenny, M, Q or exploding fountain pens.
