China Airlines Flight 120 catches fire and explodes after landing at Naha Airport in Okinawa, Japan.

China Airlines Flight 120 was a regularly scheduled international flight from Taiwan Taoyuan International Airport in Taoyuan County, Taiwan to Naha Airport in Okinawa, Japan. On 20 August 2007, the Boeing 737-809 (WL) aircraft operating the flight caught fire and exploded after landing and taxiing to the gate area at Naha Airport. Four people—three from the aircraft and one ground crew—sustained injuries in the accident. The fire was caused by a loose bolt puncturing a fuel tank. The aircraft was written off.

Naha Airport is an international airport located 4 km (2.5 mi) west of the city hall in Naha, Okinawa Prefecture, Japan. It is Japan's sixth busiest airport and the primary air terminal for passengers and cargo traveling to and from Okinawa Prefecture, Japan. It handles scheduled international traffic to Taiwan, Hong Kong, South Korea, Thailand, Malaysia, Singapore and mainland China. The airport is also home to Naha Air Base of the Japan Air Self-Defense Force.

Okinawa Prefecture is the southernmost and westernmost prefecture of Japan. It consists of three main island groups—the Okinawa Islands, the Sakishima Islands, and the Daitō Islands—spread across a maritime zone approximately 1,000 kilometers east to west and 400 kilometers north to south. Despite a modest land area of 2,281 km², Okinawa's territorial extent over surrounding seas makes its total area nearly half the combined size of Honshu, Shikoku, and Kyushu. Of its 160 islands, 49 are inhabited. The largest and most populous island is Okinawa Island, which hosts the capital city, Naha, as well as major urban centers such as Okinawa, Uruma, and Urasoe. The prefecture has a subtropical climate, characterized by warm temperatures and high rainfall throughout the year. People from the Nansei Islands, including Okinawa, the Sakishima Islands, and parts of Kagoshima Prefecture, are often collectively referred to as Ryukyuans. However, in reality, there are significant cultural and customary differences between individual islands and even between local communities.
