Investigation Summary
The hijacking of Flight 61 exposed critical vulnerabilities in Japanese airport security. The aircraft carried 503 passengers (including the hijacker, Yūji Nishizawa) and 14 crew members, totaling 517 souls on board. Nishizawa had discovered that the baggage claim area at Haneda Airport could be used to bypass security checkpoints to reach departure gates. To exploit this, he checked a knife into his luggage on a separate flight to Osaka, retrieved it upon return to Tokyo, and then carried it onto Flight 61 as hand luggage. Remarkably, Nishizawa had attempted to warn authorities and media outlets about this security loophole a month prior, even requesting a job as a security guard, but his warnings were largely ignored. During the flight, Nishizawa used the knife to threaten a flight attendant and gain entry to the cockpit. After stabbing Captain Nagashima, he attempted to pilot the aircraft himself, drawing on his experience with flight simulators. The situation was only resolved when First Officer Kazuyuki Koga and off-duty pilot Junji Yamauchi forced their way back into the cockpit to restrain Nishizawa and recover the aircraft from a dangerous low-altitude descent over Tokyo Bay.
Final Conclusions
The investigation concluded that the incident was a premeditated hijacking facilitated by systemic security failures at Haneda Airport. The hijacker, Yūji Nishizawa, was found to have Asperger syndrome and had consumed a large dose of SSRI antidepressants prior to the flight. In 2005, he was found guilty of murder; however, the court determined he was of unsound mind at the time of the crime and therefore only partly responsible for his actions. Despite this finding of diminished responsibility, he was sentenced to life imprisonment. The Japanese Transport Ministry subsequently mandated comprehensive revisions to airport security, specifically closing the loophole between baggage claim and departure areas and tightening hand-luggage inspections.

Systems & Failure Modes
Cockpit Door
At the time of the incident, cockpit doors were not reinforced to the standards later mandated after the September 11 attacks, allowing the hijacker to gain entry by threatening a crew member.
Airport Security Checkpoints
A flaw in the airport layout allowed passengers to move from the unsecured baggage claim area back into the secure departure zone without re-clearing security.

Safety Actions & Advisories
Security Loophole Closure
The Japanese Transport Ministry ordered a comprehensive revision of airport layouts to ensure passengers could not access departure gates from baggage claim areas without security screening.
Enhanced Baggage Screening
Stricter checks for hand-carried baggage were implemented at all Japanese airports following the discovery of how the weapon was smuggled.
