Japan Air Lines Flight 351 was a scheduled passenger flight from Tokyo Haneda Airport to Fukuoka that was hijacked by members of the Red Army Faction of the Japan Communist League on March 31, 1970, in an incident usually referred to in Japanese as the .
Background
In 1966, the New Left student organization the Communist League, defunct since 1960, reformed, becoming known as the . At this time, the "Kansai faction" of the Second Bund, based out of Doshisha University in Kyoto and led by Kyoto University philosophy major dropout , comprised the far left wing of the already far-left Second Bund. Around June 1968, the Kansai faction began calling itself the "Red Army Faction," and began making plans for a violent uprising in Japan, originally intended to coincide with the 1970 Anpo protests.
The main theory of the Red Army Faction was that by first carrying out a successful armed proletarian revolution in Japan, Japan would become the headquarters of a worldwide revolution against the United States of America and its allies, and the Red Army Faction would become the leaders of that revolution.
Finding the rest of the Second Bund unamenable to the cause of immediate armed revolution, the Red Army Faction signaled its open split from its parent organization in 1969. On September 5, Takaya and other Red Army Faction members publicly appeared at Hibiya Public Hall in Tokyo to declare the independence of the Red Army Faction from the Communist League and announce the start of an immediate armed revolution.
In early 1970, Shiomi began making plans to hijack a Japanese airliner, codenamed "Operation Phoenix," that would allow group members to fly to Cuba and continue their training. However, just before the hijacking could take place, Shiomi was arrested by chance on the street in Komagome, Tokyo on March 15, 1970, having been mistaken for a common thief. Nevertheless, the remaining hijackers pressed on with their plans; on March 31, 1970, nine members the Red Army Faction, armed with katana swords and a homemade bomb, hijacked Japan Airlines Flight 351, a domestic Japan Airlines Boeing 727 out of Tokyo International Airport carrying 129 other people aboard.
Hijacking
Approximately 20 minutes after takeoff, a young man named Takamaro Tamiya got up from his seat, drew a katana and shouted, "We are Ashita no Joe!" He stated his intent to hijack the plane and instructed the other hijackers to draw their weapons. The hijackers then took 129 people (122 passengers and seven crew members) hostage and commanded the pilots to fly the plane to Havana, Cuba, where they intended to receive training by communist military groups. The hijackers were then informed that the aircraft, a Boeing 727, was not capable of making such a journey, due to the plane's inability to hold the necessary amount of fuel. Upon learning of this, the hijackers insisted that the plane be diverted to Pyongyang, North Korea, after stopping to refuel in Fukuoka. Upon arrival at Fukuoka, the police convinced the hijackers to release 23 of their hostages, and the pilots were given a map of the Korean Peninsula. Attached to the map was a note which instructed the pilots to tune their radios to a specific frequency. The air traffic controllers, who were aware of the situation, intentionally gave the pilots incorrect directions in an effort to have them land at Gimpo Airport in Seoul, South Korea, where they had disguised the airport as being North Korean. Despite this, the hijackers quickly realised that they had been tricked, and Japan's Vice Minister for Transport, Shinjiro Yamamura, had volunteered to take the place of the remaining hostages, to which the hijackers accepted. They then proceeded to Pyongyang's Mirim Airport, with Yamamura now as hostage, where they surrendered to North Korean authorities, who offered the whole group asylum.
Using North Korea as a base, they sought to incite rebellion in South Korea and elsewhere across East Asia. The plane carrying Vice Minister Yamamura and the remainder of the crew was released two days later and returned to its gate at Haneda Airport at 9:39AM on April 5.
