Japan: deepfake checks commissioned by Yomiuri find an online job applicant likely used AI to impersonate a real engineer's face and identity

The Yomiuri Shimbun reported on 19 March 2026 that in early March an applicant in a Tokyo IT company's online mid-career job interview used the name, career history and apparent face of a real engineer who heads a Tokyo software company. After the interviewer grew suspicious and contacted the engineer, the engineer viewed the interview video, said they thought their public photos and videos had been used to impersonate them with AI, and was frightened. Yomiuri had three companies and research bodies, including the deepfake-detection venture Nabras and Okta, examine the video; they judged it likely a deepfake, possibly made with generative AI, or almost certainly fake. Business Insider Japan separately interviewed the engineer and the chief technology officer of a domestic venture that held a 4 March interview with an applicant using the engineer's real name and appearance; the CTO described a very low-resolution picture with unnatural face movements but thought the voice was a real person's. Who the applicant was is not established.

AI system as recorded: An unidentified AI face-altering video tool, which three examiners commissioned by Yomiuri judged had likely been used to make the applicant's interview video (tool and operator not identified)

What Happened

The interview. The Yomiuri Shimbun (19 March 2026) reports that in early March a Tokyo IT company held an online mid-career interview with an applicant who said he had been born and raised in the United States, asked for fully remote work abroad and ended the interview after about two minutes when told the job required office attendance. The applicant had applied through a Japanese recruitment platform with an English CV. Afterwards the suspicious interviewer opened the business social network page listed on the CV and found the profile of a real engineer who heads a Tokyo software company; the CV's education and career matched the engineer's.

The engineer's account. Contacted by the interviewer, the engineer watched the video and, Yomiuri reports, thought the engineer's own face photos and videos published online had been used for the impersonation with AI, and was frightened. The engineer said they feared that someone impersonating them might be hired. When the engineer asked on X for similar cases, another Tokyo company replied that it had received an application. Business Insider Japan reports that the engineer had not applied to or attended the interview, and that the engineer and the company posted the case on X on 5 March to warn others.

The AI finding. Yomiuri obtained the interview video from the engineer and asked three companies and research bodies, including the deepfake-detection venture Nabras and the US IT company Okta, to examine it. They judged it likely a deepfake, possibly made with generative AI, or almost certainly fake, citing unnatural boundaries between forehead, hair and background, moments when the eyes shifted position and a mismatch between mouth movements and audio. Business Insider Japan quotes the interviewing CTO as describing an extremely low-resolution picture with unnatural face and teeth movement, while judging that the voice was probably a real person's rather than synthetic.

Limits. The applicant's identity and aim are unknown. Okta and Trend Micro describe North Korean IT workers using AI to pose as others in interviews abroad, but no source attributes this applicant to them. The two outlets do not state explicitly that they describe the same company's interview, although both describe an interview ended early over office attendance.

Reported harm

According to the Yomiuri Shimbun and Business Insider Japan, an applicant in a company's online job interview used a real engineer's name, career and apparent face, and the engineer said they were frightened that someone impersonating them might be hired.

Outcome

Unknown

The engineer and the interviewing company publicised the case on X on 5 March 2026; after the engineer asked there for similar cases, another Tokyo company said it had also received an application. No police report, platform action or identification of the applicant is reported.

What remains unknown

  • Who the applicant was and what the applicant intended.
  • Which tool produced the altered video.
  • Whether the two outlets describe the same company's interview.
  • Whether any police report was made.

What the evidence supports

AI involvement: suspected. Yomiuri had the interview video examined by three companies and research bodies, including the deepfake-detection venture Nabras and the US IT company Okta; they judged it likely a deepfake, possibly generative-AI made, or almost certainly fake, and listed boundary, eye-position and lip-sync anomalies. That examined video is the one that showed the applicant with the engineer's apparent face. The examiners' wording is probabilistic, the tool and operator are unidentified, and the interviewing CTO thought the voice was a real person's.

Event countries: Japan. Affected-person countries: Japan. Court countries: Unknown.

Yomiuri reports the interview was held by a Tokyo IT company and that the impersonated engineer heads a Tokyo software company. The applicant's location is unknown. No court proceeding is reported.

Reviewed for publication 2026-10-19: Published as a core case (depicted_or_impersonated): deepfake examiners commissioned by Yomiuri judged that the video of a job applicant who used a real engineer's name and career was likely AI-made, and the engineer said the impersonation was frightening. The AI involvement is suspected on the strength of that examination; the applicant is unidentified.

People described

An engineer in their forties who heads a Tokyo software company, whose name and career details were used by the applicant and whose public photos and videos, the engineer believes, were used to impersonate them (not named here)

People reported harmed in this case

At least 1 person

0 AI participants · 1 other person harmed

One person is counted: the engineer whose identity and apparent face were used and who said they were frightened. The interviewers and the other company that received an application under the engineer's name are not counted as harmed people, so the figure is a lower bound.

Counted once within this case. The same person may appear in other cases. This count does not establish AI causation.

Woman in Kansai questioned for about an hour by fake police on phone and Zoom; analysis for Osaka police found the detective's face possibly an AI deepfake

In June 2026 a woman in her thirties in Japan's Kansai region received a call from a man claiming to be an Aichi Prefectural Police officer, who said a cash card in her name was linked to a fraud ring and that she was a suspect. She was moved to a Zoom call where a second man, presented as a detective, showed a police notebook, questioned her and told her to search her home on camera for her My Number card. Suspecting fraud, she recorded the exchange and ended it after about an hour; she told reporters the pressure left her flustered and feeling like a culprit. The Osaka Prefectural Police published part of the recording in August, and an analysis it requested from Trend Micro found the detective's face was possibly a deepfake altered with AI (Yomiuri, Asahi, FNN, NHK). No loss is reported.

Former NT Police assistant commissioner says an AI-generated sexually explicit video made from her official police photograph circulated among colleagues

Janelle Tonkin, a former assistant commissioner of the Northern Territory Police Force and now president of the Australasian Council of Women and Policing, said in a statement issued on 23 September 2026, after criminal proceedings on the matter were finalised, that in December 2025 she became aware that an AI-generated, sexually explicit video had been created using her official NT Police photograph; ABC News reports that the video was allegedly shared among serving members of the force and that she had taken former colleagues to court over it. She called the experience 'extremely distressing, personally and professionally' and said having her professional portrait 'turned into pornography and circulated among colleagues is something no person should have to experience'. The outcome of the court proceedings is not reported. An NT Police spokesperson said the force does not comment on internal investigations and was legally constrained from commenting on matters before the court, but that the conduct she was subjected to 'was, and always will be, totally unacceptable'; the NT Police Association condemned the conduct. Ms Tonkin said the video sat within a broader set of experiences in the force that she intends to describe later.
