History

Historical Context

The 1973 Oil Crisis marked a pivotal moment for Japan, which relied on the Middle East for 90% of its oil. Following OPEC's embargo, Japan implemented drastic energy conservation measures, cutting industrial oil use by 20%. This crisis reshaped Japan's energy policies, leading to diversification and a shift towards nuclear power, which remains significant in today's energy strategy amid ongoing geopolitical tensions.
