On June 21, 1995, a 53 year old man hijacked ANA Flight 857 when the plane was flying over northeast Japan, taking 365 people onboard hostage with a bomb, a plastic bag holding liquid sarin and a screwdriver. The suspect claimed to be a member of the cult Aum Shinrikyo, which just conducted the Tokyo subway sarin attack three months prior. Once the plane landed in the Hakodate Airport, he demanded that the leader of the cult, Asahara Shoko to be released and the plane refuelled to fly to the Haneda Airport. Once the news broke, the National Police Agency mobilized all 47 prefectural police forces across the entire country to check the passenger's list to determine who the hijacker was, supported by passengers who were able to secretly communicate with the police, they soon zeroed in on their suspect, who was a bank employee placed on leave due to mental issues. Aum Shinrikyo representatives also released a statement stating the hijacking had nothing to do with them.

To deal with the hijacking, the Metropolitan Police Department Special Armed Police (picture 2, officers in the background near the black structure under the aircraft) from Tokyo, one of two only special forces unit in Japan (only Osaka Prefectural Police has a special forces unit at the time) was flown into Hakodate by the JASDF to retake the aircraft, but in the end it was decided that Hokkaido riot police (picture 3) would storm the aircraft while the SAP would provide breaching support. Overnight, Hokkaido Prefectural Police brass and the SAP commander formulated an assault plan, and received approval from the National Police Agency and green light to attack from the Prime Minister. At 3:39 a.m. on June 22, riot police armed with batons and revolvers, ascended on the ladders, while SAP officers threw the aircraft doors open. The officers rushed in from the three left side doors, the hijacker was at the L1 door when they entered, he immediately ran towards the back of the aircraft but saw the officers rushing in from the2 door, he turned back again and was subdued by a baton strike.

The bomb was discovered to be made of clay and the bag of sarin was in fact, water. The hijacker was arrested and sentenced to 8 years of prison by the Hakodate District Court, an appeal to the Sapporo High Court would lengthen it to ten years. ANA filed a civil lawsuit against the hijacker and was awarded 53 million yen for damages. The bank he worked for formally fired him and printed an apology notice on every single newspapers in Japan and apologized once again at its shareholders meetings a couple days later.

This operation is revolutionary in many aspects in the Japan police history. It is the first and only time the police stormed a hijacked aircraft and the existence of a police special forces unit was also publicized for the first time since its formation in 1977. The next year, the NPA announced that Tokyo and Osaka police would reform their special forces unit into the Special Assault Team, (Japanese equivalent to the FBI HRT). In addition, police forces of Hokkaido, Chiba, Kanagawa, Aichi, Fukuoka and Okinawa prefectures were authorized to form their SATs as well, bringing it to 8 teams covering the entire country.
