CHAPTER 7: JAPAN’S DEFEAT IN WORLD WAR II
Brief Summary of Pacific War
Japan Sweeps into SEA
0 Attack on Pearl Harbour coordinated with advance
into SEA.
0 1941 – Hong Kong, Malaya, Philippines & Burma fell
0 1942 – Singapore & Dutch East Indies fell
0 Thailand signed alliance with Jp to avoid being
conquered
0 French Indo-China became Jp ally as well.
0 SEA came under Jp control by 1942
Japanese strategy
0 Jp believed that its quick and early successes would
convince Allies to negotiate for peace
0 Thought that US would be unwilling to pay price of
long and total war
0 Underestimated US determination to fight back;
Pearl Harbour attack united US in bitter hatred of Jp
The Tide Turns…
0 America rebuilt Pacific
Fleet & was out for revenge.
0 Naval battle at Midway saw
America cripple Jp Navy.
0 U.S. marines began the
“island-hopping” strategy
hatched by Admiral Chester
Nimitz
American navy wins a decisive
battle against the Jp at the
Pacific island of Midway
By early 1945…
0 Allied forces had retaken
Philippines, fighting to
retake Burma, &
preparing to retake
Malaya.
0 Island hopping brought
U.S. marines within
striking range of Japan.
General Douglas Macarthur – “I have
returned!”
Approaching Japan
0 Costly battles at Iwo Jima &
Okinawa convinced Americans
that invasion of Japan would
result in high casualties.
0 Jp kamikaze tactics showed
desperation
0 The solution?

casualty rate in any battle in
history.

CHAPTER 7: JAPAN’S DEFEAT IN WORLD WAR II
Economic strength
0 US – largest industrial producer in the world with
abundant raw materials
0 Jp had only one-tenth the productive capacity of US
0 US able to produce more ships, planes, tanks, guns
and bombs than Jp
Military production by Jp and US during WW2
(Source 7.2 on p.194)

Guns

Economic strength
0 US submarines sank more than 75% of Jp
merchant ships, crippling Jp supplies of raw
materials
0 US bombing destroyed Japanese homes and
factories
0 1945 – Jp ppl starving & facing collapse of
industrial production
Contribution of women to war effort
0 US women made significant
contribution to war effort
0 Worked in factories to produce
weapons and military supplies
0 Jp women stayed at home to fulfill
role of mother and child-bearer
Military strength
0 US was still militarily strong enough to fight back
despite Pearl Harbour attack
0 Three US aircraft carriers survived as they were
not at harbor during attack
0 Jp also failed to destroy fuel storage &
maintenance facilities – this enabled US to rebuild
Pacific Fleet and retaliate later
Military strength
0 Three key events illustrated US military strength:
0 Doolittle Raid (Apr 1942)
0 Battle of Coral Sea (May 1942)
0 Battle of Midway (June 1942) – decisive battle that
severely weakened Jp air and sea capabilities;
turning point in Pacific War
0 Read pp.196-197 for details
Battle of Midway
0 Jp wanted to destroy what was
left of US fleet in final battle
0 Once US fleet destroyed, Jp
could use Midway to threaten
Hawaii and US Pacific coast
0 Yamamoto assembled a huge
fleet and confident of victory
American navy won a decisive
battle against the Jp at the
Pacific island of Midway
Battle of Midway
0 US broke Jp naval codes
0 After withstanding the first Jp
strike, US bombers attacked Jp
fleet while Jp planes were
refueling
0 Jp lost 4 aircraft carriers, over
300 planes and their best
trained pilots
American navy won a decisive
battle against the Jp at the
Pacific island of Midway
Over-extension of Japanese Empire
0 Jp Empire had overstretched itself
0 Rapid conquests gave Jp too large an area to control
0 Jp struggled to defend its massive empire due to its
limited resources and manpower
0 Jp also had to fight on many fronts – China, SEA,
Pacific – due to vastness of its empire
How do you defend an empire as large as this?
Island-hopping
0 US forces began ‘island-hopping’ campaign
0 Aim was to leapfrog across the Pacific by capturing
strategically important islands one by one until they
reached Jp
0 Guadalcanal  Marianas Islands  Philippines 
Iwo Jima  Okinawa  bloody fighting and severe
casualties on both sides (Read p.199 for details)
Kamikaze attacks
0 From 1944, Jp resorted to kamikaze attacks in their
desperate attempts to defend their territories
0 Suicide missions by Jp pilots against Allied ships
0 Sank 21 US ships; more than 5000 Americans killed
– too little too late to reverse situation
0 Strengthened US resolve to bring about quick end to
the war to minimize losses
Resistance to Japanese rule
0 Jp brutality and mistreatment of local Asian
populations led to increasing hostility to Jp rule
0 Kempeitei carried out Sook Ching which killed
about 50,000 Chinese in Singapore
0 Construction of Thai-Burma Death Railway led to
deaths of large numbers of Asian labourers and
Allied prisoners of war (see p.200)
Resistance to Japanese rule
0 Opposition movements were formed to resist Jp
rule
0 E.g. Force 136, Malayan People’s Anti-Japanese
Army (MPAJA)
0 Deployment of soldiers to keep locals under control
further drained Jp resources available for war
Allied victory in Europe
0 Allied victory in Europe in May 1945 meant that Jp
could no longer rely on Germany to distract Allies
0 Allied forces could be concentrated against Jp –
Soviets promised to bring their troops to the East to
help with final assault
0 Jp leaders knew that it was a matter of time before
Allies would win war
Allied victory in Europe
0 But they refused to accept Allied demands for
unconditional surrender – humiliating stigma to Jp
0 Feared that Allies might remove Jp emperor and try
him as war criminal
0 Continued fighting while attempting to negotiate
peace terms with Allies through the Soviet govt.
Dropping of atomic bomb
0 US President Truman decided to use atomic bombs
to force Jp surrender without having to invade Jp
0 Bloody battles at Iwo Jima & Okinawa convinced US
that invasion of Jp would result in heavy casualties
0 Another motive was to impress and intimidate
Soviet Union with US power at the onset of Cold
War (read pp.203-204)
Dropping of atomic bomb
0 US dropped atomic bombs on Hiroshima (Aug 6) and
Nagasaki (Aug 9).
0 More than 100,000 killed instantly
0 Destruction shocked the Jp military & Emperor; no
way Jp could compete with such weaponry.
0 Aug 15: Emperor Hirohito announced unconditional
surrender
Was dropping of A-bomb
necessary?
0 Yes: Hasten defeat of Jp
0 Shorten agony of war and save lives
0 Costly battles during island campaign
0 Jp atrocities, mistreatment of POWs
Was dropping of A-bomb
necessary?
0 No: Jp was on verge of defeat
0 Jp was severely weakened and ready to
surrender
0 US ‘island-hopping’ campaign inflicted
heavy damage to Jp military strength
0 US bombing of Jp factories crippled Jp
industrial production
