1. ACCIDENTS in JAPAN
I. NUCLEAR ACCIDENTS
II. AIRLINES ACCIDENTS
III. FUJIN RAIJIN ACCIDENT
2. They classify accidents into two types:
Bussonjiko: an accident involving damage to property.
Jinshinjiko: an accident resulting in injury or death.
3. Nuclear Accident
Tokaimura nuclear accident
There have been two Tokaimura nuclear accidents.
On 11 March 1997, in a Dōnen plant.
On 30 September 1999, in a JCO plant.
The first Tokaimura nuclear accident was the nuclear disaster which
occurred on 11 March 1997, in a nuclear reprocessing plant of the Dōnen (Power
Reactor and Nuclear Fuel Development Corporation).
Another name is the Dōnen accident
On the night of 11 March 1997, a small explosion occurred in a nuclear reprocessing
plant of the Dōnen. In this accident, approximately 40 workers were exposed to radiation.
The second and more serious Tokaimura nuclear accident (Japanese: Tōkai-mura JCO-
rinkai-jiko) indicates the nuclear disaster which occurred on 30 September 1999, resulted
in two deaths.
It was the worst civilian nuclear radiation accident in Japan prior to the Fukushima Daiich
nuclear disaster of 2011. International Nuclear Event Scale (INES). This scale runs from
0, indicating an abnormal situation with no safety consequences, to 7, indicating an
accident causing widespread contamination with serious health and environmental
effects.
4. The Fukushima Daiichi nuclear disaster was a series of equipment
failures, nuclear meltdowns, and releases of radioactive materials at the
Fukushima I Nuclear Power Plant, following the Tōhoku earthquake and
tsunami on 11 March 2011.
It is the largest nuclear disaster since the Chernobyl disaster of 1986, and
only the second disaster (along with Chernobyl) to measure Level 7 on the
International Nuclear Event Scale.
When the Tohoku earthquake occurred, the reactors on Units 1, 2, and 3
were operating, but those on Units 4, 5, and 6 had already been shut down
for periodic inspection. Units 1, 2 and 3 underwent an automatic shutdown
(called SCRAM) when the earthquake struck
5.
6. Airline Accidents
Japan Airlines Flight 123 was a Japan Airlines domestic flight from Tokyo International
Airport (Haneda) to Osaka International Airport (Itami). On Monday, August 12, 1985,
suffered mechanical failures 12 minutes into the flight and 32 minutes later crashed into
two ridges of Mount Takamagahara in Ueno, Gunma Prefecture, 100 km from Tokyo.
The crash site was on Osutaka Ridge near Mount Osutaka. All 15 crew members and
505 out of 509 passengers died, resulting in a total of 520 deaths and four survivors.
It is the deadliest single-aircraft accident in history, and the second-deadliest accidental
plane crash in history
*All Nippon Airways Flight 60 crashed into Tokyo Bay while on approach to land at
Tokyo International Airport on 4 February 1966 killing 133 people in the deadliest single-
plane incident until 1971. The cause of the crash is undetermined.
*All Nippon Airways Flight 61—Hijacked and taken back over Tokyo, Japan.
BOAC Flight 911—In flight structural failure due to clear-air turbulence near Mount Fuji,
Japan.
*Canadian Pacific Airlines Flight 402— Crashed on landing at Tokyo International
Airport in fog.
*Japan Airlines Flight 123—Crashed into Mount Osutaka, Japan.
*Japan Airlines Flight 907 and Japan Airlines Flight 958—Nearly collided near Yaizu,
Japan.
*China Airlines Flight 120—Caught fire and exploded on Naha Airport,Okinawa,Japan.
7. Japan Sasago tunnel collapse December 2012
Nine people are now confirmed to have
died after a major tunnel collapsed in Japan
The bodies were found in three vehicles that were crushed by fallen concrete panels
in the Sasago tunnel about 80km (50 miles) west of the capital Tokyo
A fire broke out after the tunnel caved in on Sunday
and a number of survivors fled to safety on foot
The usually busy tunnel remains closed, as police are investigating potential
negligence.
There will be serious questions about how a major tunnel on one of Japan's most
important traffic arteries could have failed so catastrophically,
The private company that runs the highway has said the tunnel was given a major
inspection just two months ago and was given a clean bill of health, our
correspondent adds.

9. Fujin Raijin Accident – 2007
Japan’s worst amusement-park disaster happened in
2007 at Expoland, outside of Osaka.
The Fujin Raijin II roller coaster derailed, sending cars
flying off the tracks, which killed a college student and
injured 19 others.
The accident revealed that the coaster’s axles had not
been replaced in 15 years. Even worse, they reopened
after the accident and safety inspectors discovered
another train with an axle about to snap that the park
was still letting run. Expoland closed soon after,
blaming “a lack of customers.”
