Then entered a publishing company, and was assigned to an editorial department of a week or a monthly. But he engaged wholly in reporter activity than editing work. In less than 3 years He resigned the company and became a freelance writer. But while he had worked as a writer, He temporarily became an employee of advertising agency for 7 years and handred PR. Then he resighned the company in 1980 and returned to a free lance writer in earnest which lead to the present. He is a nonfiction novelist and a journalist.

 A writing which theme in an organized crime syndicate such as Yamaguchigumi and the black world take a big concern for Mizoguchi Atsushi. And there are a number of related writing such as “Blood and rivalry. The third head of Yamaguchigumi”, “The forth boss of Yamaguchigumi. A madden lion”, “Documentary the fifth leader of Yamaguchigumi” which are in a Yamaguchigumi series, besides it there is “ Rules in chinese <black society> China mafia”, “Darkness of pachinko 30trillion yen”, “Heisei black business of sigotosi”.
He is considered as "the first person of Yamaguchigumi watching", but because he writes the truth based on inside information without flattering ang restraint, He received a threat and a surprise attack of speech interference from a person concerned with organized crime syndicate three times in the past.

 The first time was in August 29, 1990 just after publication of “Documentary the fifth leader of Yamaguchigumi”. As a counterattack against that writing, He was stabbed in left side back by the man who was supposedly a member affiliated with Yamaguchigumi with an edged tool. And he got a serious wound of complete cure in two months.

 The second time was as a cause on Mizoguchi’s undersigned article “Destruction previous night of the strongest corps Yamaguchigumi who is in a corner” which written in weekly photomagazine “Friday” issued in July 31,1992. In August 14, of the same year, a deputy editor chief of the magazine got a blow with a special policeman's club by two members of Ymaken group affiliated with Yamaguchigumi. And he got injury to sew 7 stitches on his head.

 As for the third time, as a cause on Mizoguchi’s undersigned article “ The 6th Yamaguchigumi reader, Tsukasa Shinobu. Real face of a intelligent reader of armed battle group” written in January 2006 issue of “the monthly Gendai”,
And in January 8th of the same year the case that Mizoguchi’s son was stabbed with edged tool from behind by a member of Kenkokukai of Yamaken group affiliated with Yamaguchigumi happened. After his attack, when that yakuza member escaped, he dropped his mobile telephone. And this proof triggered off three people such as a practice criminal to be arrested and prosecuted. And each of them received a conviction afterwards.

 But Mizoguchi continues writing same as before without frinching from these attacks still now. With his motto of "Exposing it to the day light is the best way to sterilize " (by U.S. Supreme Court judge Lewis.D.Brandeis), He writes the truth severely for a problem person.

In 2006, "A resume of a witch. Kazuko Hosoki " serializated by “ the weekly Gendai” was regarded as a defamation by Kazuko Hosoki herself who was written about in that serialization. And she instituted a suit for damages of about 600million yen against the president of Kodansha which is a publisher of the magazine. Though Mizoguchi Atsushi was a writer of that serialization article, he was not accused. But in September of the same year, He decided to be a supporting participation to confronts Mrs Hosoki in court, too.
