Tokyo

The airplane departed Tokyo on a local test flight on behalf of the Japan Civil Aviation Authority. While flying off Chiba, it went out of control and crashed into the Bay of Tokyo. All 13 occupants were killed, among them Shikasaburo Yamakawa, Chief of Inspectors of the Bureau of Civil Aviation.

The crew was returning to Germany following a promotional tour in Far East. While approaching Manila, all four engines stopped. The Captain ditched the aircraft off Manille. All eight occupants were rescued and the aircraft named 'Brandenburg' was damaged beyond repair.

The single engine airplane departed Tokyo-Haneda Airport at 0850LT on a local training flight, carrying three crew members. Weather conditions were marginal with a limited visibility caused by fog. Five minutes after takeoff, while completing an approach to Haneda Airport, the airplane collided with a Mitsubishi Ki-1 (Hanriot HD-14) that was also completing a local training flight out from Tokyo-Haneda Airport. Registered J-BIDH and operated by the Japan Flying School, the aircraft was carrying two pilots, one student and one instructor. Following the collision, the Mitsubishi dove into the ground and crashed onto a house located in the district of Morigasaki. Out of control, the Fokker crashed on the factory of the Yamamoto Rush Manufacturing Company also located in the district of Morigasaki, less than 3 km northwest of Haneda Airport. Both pilots on board the Mitsubishi were killed. All three crew on board the Fokker were killed as well as 80 people on the ground, most of them employees of the YRMC and/or locals who wanted to take part to rescue operations.
Fokker crew:
Haruo Tanaka, instructor,
Tadashi Sakai, student pilot,
Ryosaku Aoki, student pilot.
Mitsubishi crew:
Toshio Fujita, instructor,
Bunzo Ito, student pilot.

The pilot André Japy was trying to establish a new record on a flight from France to Japan. On the leg from Hong Kong to Tokyo, while approaching Fukuoka, he encountered poor weather conditions with thunderstorm and turbulences. The airplane went out of control and crashed on the slope of Mt Sefuri (1,054 metres high). The aircraft was destroyed and the pilot was seriously injured.

Named 'Le Trait d'Union II', the aircraft departed Paris-Le Bourget Airport on 11SEP1931 for a nonstop flight to Tokyo, the second attempt for this crew. A first attempt was made last 14 of July but the aircraft crashed in Sherbati, Russia. While cruising east of Ufa, over the Ural Mountains, the crew encountered problems while flying in poor weather conditions. Marcel Doret asked his colleagues to take their parachute and bail out. He bailed out few seconds later and landed safely when the aircraft crashed and was destroyed. At this time, he realized his both friends remained in the cabin and did not bail out for unknown reasons. Both aviators Joseph Le Brix et René Mesmin were killed.

The crew was attempting the first non stop flight from Paris to Tokyo and departed Paris-Le Bourget on 12 July 1931 at 0443LT. While cruising over the region of Nizhneudinsk, the engine failed due to icing conditions. Le Brix and Mesmin bailed out while the pilot Doret attempted to make an emergency landing near Sherbati. The aircraft eventually crashed in a wooded area and was damaged beyond repair as the engine and the right wing were torn off. The aircraft was christened 'Le Trait d'Union'.
Crew:

The pilot Seiji Yoshihara was attempting a second non stop flight from Tokyo to Los Angeles on this single engine aircraft owned by Hochi Shimbun. While flying off Nemuro, the airplane crashed in unknown circumstances into the Nemuro Bay. While the pilot was rescued seven hours later, the aircraft sank and was lost. A first attempt to cross the north Atlantic ocean from Tokyo to Los Angeles failed last 14 of May when the aircraft crashed into the sea some 40 miles off the Kurile Islands.

The single engine departed Tokyo on its second test flight, carrying eight crew members, engineers and pilots. The airplane crashed in unknown circumstances, killing all eight occupants. The first test flight has been completed the day prior to the accident.
