Fans Made ChatGPT Talk Like Kazuko Hosoki. Her Official Site Now Sells Her AI Voice

On the official website of Six Star Astrology (Rokusei Senjutsu), the fortune-telling system Kazuko Hosoki invented, there is a digital archive page with a red box marked LIMITED. The headline inside is written in her voice, in first person: “I’ll tell you your fate myself.” Below it sits a button to play a sample clip. Hosoki died on November 8, 2021, at 83. The voice on the page is synthesized by AI, and since September 18 it has been for sale.

Hosoki was a fortune-teller who became a fixture of Japanese television, once nicknamed the queen of ratings, and her blunt on-air verdicts, including telling people they would go to hell, turned into catchphrases. Her books on Six Star Astrology, which reads a person’s fortune cycles from their birth date, hold a Guinness record as the best-selling fortune-telling books in the world. The new project pairs EmbodyMe, a Tokyo company that builds video-generation AI, with Hosoki’s office and the company that runs the official Six Star Astrology site, a wholly owned subsidiary of the mobile content company CYBIRD. The site is supervised by Kaori Hosoki, Kazuko’s adopted daughter and the heir to her system. EmbodyMe’s avatar service, DigiSelf, recreated Hosoki’s face and voice.

The free part is a video. An AI Hosoki in a black lace jacket, framed by an ikebana arrangement and a hanging scroll of koi, talks about the reaction to the Netflix series about her life, about the life itself, and about how to live now. The paid part is three voice readings, tax included. A money reading in five chapters costs ¥1,650. A reading about your life’s turning point, in six chapters, also costs ¥1,650. The longest, “Seven Great Turns in Your Life,” runs twelve chapters for ¥1,980, moving from your talents and the people who will help you to a closing chapter on what she would like you to fix about yourself. Before buying, you register a name and a birth date. Even the blurb for the money reading is written as her confession: she, too, once worked herself ragged and still had nothing left over.

The press releases say the AI was built from a large archive of her past video and audio, and that it reproduces her expressions, her way of speaking and her pauses. They do not say whether the text of each reading is generated by AI for each buyer’s birth date. On the site, the three voice menus sit in the same list as its ordinary paid readings, such as a general forecast for October 2026, and share the same chapter-by-chapter format. The safe reading is that AI supplies the voice. The words themselves may be the site’s usual birth-date readings.

The timing comes from Netflix. In January the service announced *Straight to Hell* (*Jigoku ni Ochiru wa yo*), starring Erika Toda, which premiered worldwide on April 27 and follows Hosoki from postwar hunger and nightclub work to the title “Queen of Ginza” and then to television stardom as a fortune-teller. The AI project also launched alongside a book: a print-on-demand reissue of her 1988 memoir, *Onna no Rirekisho* (A Woman’s Résumé), out September 15 for ¥2,860. CYBIRD’s press release leads by calling it a reference work for the Netflix drama.

A free Hosoki was already available. In late May, a ChatGPT prompt spread on Japanese X that asked the chatbot to tell fortunes in the style of Kazuko Hosoki from nothing more than a birth date and gender. The news site shiritomo wrote up the craze and pointed out that ChatGPT was not actually running her method. In June, two writers on the blogging platform note posted near-identical versions of the prompt. It tells the model to speak in blunt, declarative phrases, never hedge, be a little frightening, feel free to be somewhat prejudiced, and always end on a hopeful note; the method is a mix of Four Pillars of Destiny and Six Star-style fortune cycles. One of them got it from a friend and had heard it worked on ChatGPT, Gemini and Claude alike. His own reading opened by telling him to brace himself, and the marriage section concluded that until he learned to set aside half his pride, any marriage he entered would end in divorce.

Put the two side by side and the price tag starts to make sense. The prompt copies a manner of speaking, which anyone can do for free. What the official site sells is what fans cannot copy: her face and voice, her name, and the Six Star Astrology brand that her heir still runs. The archive page leans on that hard, calling it a one-of-a-kind experience available only on this site. The small print underneath adds that it is for a limited time.

EmbodyMe wants to go further. Its release says DigiSelf can make the same person speak other languages in their own face and voice, and can generate video in real time, so the company is considering content for overseas audiences and a version where users talk to the Hosoki avatar directly. If that ships, the official product will look a lot like the fan prompt: you ask, “Hosoki” answers. The remaining differences would be the face, the voice and the checkout page.

EmbodyMe’s announcement describes the project as bringing Hosoki back. According to her publisher, she wrote the 1988 memoir to settle accounts with her past and start over. Thirty-eight years later the book is back in print, and on the archive page, an AI-generated Hosoki is talking about a TV show about herself.
