Early religious career
While working in Tokyo, one of Nagaoka's followers introduced her to . Minemura was a businessman who, together with his brother-in-law and medium , founded , a Shinto study circle. From 1936 to 1942, Minemura commissioned Nagaoka to conduct rites and provide guidance for conducting businesses at his copper mine.

, which helped to form Nagaoka's belief in a "world renewal" and influenced her rituals.
In 1943, she published , a collection of her teachings which preached a "world renewal" following a period of chaos. She believed in a divine, peaceful land that would emerge following "
convulsions of nature". The publication, along with Minemura's own mining business, attracted the attention of the police, who conducted a raid on Jiu lodgings (where Nagaoka and a number of her followers lived) on 8 February 1945. After discovering a copy of ''Makoto no hito'', Nagaoka was arrested and imprisoned for about a month, until her release on 3 March. After her release, Minemura fell ill and his mining business declined. Minemura and his close followers evacuated from Tokyo during an
Allied bombing of Tokyo on 25 May 1945, and Nagaoka declared herself the new spiritual center of Jiu on 31 May, cementing her role as the leader of Jiu.
Leader of Jiu

At this time, somewhere between ten and thirty followers would live in the same house as Nagaoka, though not all members lived with her. Nagaoka's leadership saw a religious focus on her oracles, performed through
spirit-writing, which became the infallible authority of Jiu. Not only did the oracles set out the details of the world renewal process and post-world renewal society under the ''

next month, though the travels had weakened Nagaoka, which was viewed by her followers to represent dangers facing the nation. The sight of Go Seigen and Futabayama Sadaji, two celebrities in the town of Kanazawa, along with seemingly-fulfilled prophecies of earthquakes attracted more media attention. Their activities also attracted an ''Asahi Shimbun'' journalist who, hoping to see his acquaintance Futabayama return to the sumo wrestling world, investigated the group and reported his information to the local police. The local police was, in turn, concerned about Jiu using Futabayama's celebrity status to spread their beliefs. With the journalist's information, the police raided the group's headquarters on 18 January 1947, though Nagaoka refused to meet with the police.
On 21 January, after learning that Nagaoka and her followers were planning to escape the town at night, the police raided the headquarters a second time, arresting Nagaoka along with Futabayama (who attempted to fight off the police) in front of groups of journalists and cameramen, who would later term the raid "" or the "". The charges cited by the police were violation of food laws (food were accumulated for the apocalypses) and ownership of prohibited weapons, including several old swords and knives. Nagaoka was examined by a

doctor, who concluded that she was suffering from delusions but not a danger to the public. As a result, she was released on 23 January with no charges, though Jiu was now branded as an "evil cult" by the media. Nagaoka's psychological examination by a university doctor was seen by the media as a sign that she was mentally unstable, though the results actually exonerated her of mental illnesses. Jiu's reputation following the Kanazawa incident never recovered.
