Worked example: explain two ways different

Explain two ways in which Japan’s relations with the West in 1858 were different from its relations with the West in 1902. (6 marks)

1. Equality: in 1858 Japan was forced to accept unequal treaties; in 1902 Britain signed an alliance with Japan as an equal partner.
2. Power: in 1858 Japan could not resist Western warships; by 1902 it had a modern army and navy and had defeated China, making it a regional power.

Essay plan in outline

“Contact with the West was the main reason for Japan’s transformation in the years 1853–1912.” How far do you agree?

• For: Perry and the unequal treaties triggered the Tokugawa’s fall; Western models for the army, constitution, industry and education; the Iwakura Mission.
• Against: Japanese leadership (Satsuma and Choshu oligarchs); the drive for national strength; existing literacy and commerce; war with China and Russia as engines of change.
• Judgement: the West provided the shock and the models; Japanese leaders chose how to use them.

Turning points to argue about

• 1853–54: the end of seclusion — the start of every later change.
• 1868: the Restoration — new leaders with a programme of modernisation.
• 1905: victory over Russia — Japan recognised as a great power.
• 1931: Manchuria — the army acts independently and the road to war begins.

Common mistakes and exam traps

• Treating the Restoration as a revolution from below. It was led by samurai of a few domains.
• Assuming the Meiji Constitution created democracy. The emperor was sovereign; the army answered to him.
• Ignoring continuity. Village life changed slowly even as cities modernised.
• Confusing the Boxer Rebellion (1900) with the Sino-Japanese War (1894–95).
• Covering one topic only in (c). Use at least two key topics.

Frequently asked questions

Why did Japan modernise so quickly? Fear of colonisation, determined leaders and a literate population.

Why did the military gain power in the 1930s? Depression, distrust of party politicians, success in Manchuria and the army’s independence under the constitution.

Why did Japan surrender in 1945? The atomic bombs and the Soviet declaration of war.
