ANA Flight 61 is hijacked in Tokyo, Japan by Yuji Nishizawa.

On July 23, 1999, an All Nippon Airways Boeing 747-481D with 503 passengers on Flight 61, including 14 children and 14 crew members on board, took off from Tokyo Haneda Airport in Ōta, Tokyo, Japan and was en route to New Chitose Airport in Chitose, Japan, near Sapporo when it was hijacked by Yūji Nishizawa.

Aircraft hijacking is the unlawful seizure of an aircraft by an individual or a group. Dating from the earliest of hijackings, most cases involve the pilot being forced to fly according to the hijacker's demands. There have also been incidents where the hijackers have overpowered the flight crew, made unauthorized entry into the cockpit and flown them into buildings—most notably in the September 11 attacks—and in some cases, planes have been hijacked by the official pilot or co-pilot, such as with Ethiopian Airlines Flight 702.

Tokyo, officially the Tokyo Metropolis, is the capital and most populous city in Japan.

The Greater Tokyo Area, which includes Tokyo and parts of six neighboring prefectures, is the most populous metropolitan area in the world, with 41 million residents as of 2024.
