By 18:00 on 1 February, eight Flight 907 passengers remained hospitalized, while 22 injured passengers had been released. Two passengers remained hospitalized at Kamata General Hospital, while two other passengers remained hospitalized at Ichikawa No. 2 Hospital. In addition, the following hospitals each had one passenger remaining: Takano Hospital,
Kitasato University, Horinaka Hospital, and Tokyo Rosai Hospital. All injured passengers recovered. JAL sent apology letters to the passengers on the 747; injured passengers directly received messages, and uninjured passengers received messages via the mail. In its report on the accident, published in July 2002, the
Aircraft and Railway Accidents Investigation Commission called on the
International Civil Aviation Organization (ICAO) to make it clear that TCAS advisories should always take precedence over ATC instructions. A similar recommendation was made three months later by
Germany's accident investigation body (the
BFU) in light of the
2002 Überlingen mid-air collision. ICAO accepted these recommendations and amended its regulations in November 2003.
Criminal investigation and trial The
Tokyo Metropolitan Police Department and
Ministry of Land, Infrastructure and Transport investigated the incident. Hachitani, then 30 years old, and Momii, then 35 years old, pleaded not guilty to the charges at
Tokyo District Court in 2004. During the same year, the lawyer for Hachitani and Momii said that the pilots of the aircraft bore the responsibility for the near miss. By 16 November 2005, 12 trials had been held since the initial hearing on 9 September 2004. The prosecution argued that the two defendants neglected to provide proper separation for the two aircraft, the instructions issued were inappropriate, and that the supervisor failed to correct the trainee. The defense argued that the lack of separation would not immediately have led to a near miss, that the instructions issued were appropriate, that the
TCAS procedure was not proper, and that the Computer Navigation Fix (CNF) had faulty data. In 2006, prosecutors asked for Hachitani, then 31, to be sentenced to ten years in
prison and for Momii, then 37, to be sentenced to 15 years in prison. On 20 March 2006, the court ruled that Hachitani and Momii were not guilty of the charge. The court stated that Hachitani could not have foreseen the accident and that the mixup of the flight numbers did not have a causal relationship with the accident.
Hisaharu Yasui, the presiding judge, said that prosecuting controllers and pilots would be "unsuitable" in this case. The Tokyo District Public Prosecutor's Office filed an appeal with the Tokyo High Court on March 31. During the same year, the Japanese government agreed to pay Japan Airlines and
Tokio Marine & Nichido Fire Insurance a total of ¥82.4 million to compensate for the near miss (equivalent to ¥ million in ). On 11 April 2008, on appeal, a higher court overturned the decision and found Hachitani and Momii guilty. The presiding judge, Masaharu Suda sentenced Hachitani, then 33, to 12 months imprisonment, and Momii, then 39, to 18 months imprisonment, with both sentences suspended for 3 years. The lawyers representing the controllers appealed, but the convictions were upheld on 26 October 2010, by the
Supreme Court. ==In popular culture==
