Japan Revives Coal Power as Iran Conflict Threatens Energy Security
Tokyo is temporarily easing restrictions on coal-fired power plants in response to escalating tensions in the Middle East and the potential disruption of oil and gas supplies through the Strait of Hormuz. This move underscores Japan’s vulnerability to geopolitical instability in a region critical to its energy needs.
The Strait of Hormuz: A Chokepoint for Global Energy
The ongoing conflict has effectively blocked the Strait of Hormuz, a vital waterway for global energy supplies. This disruption is causing a surge in oil prices and keeping the yen weaker against the US dollar, which is seen as a safe-haven currency. Japan, which sources nearly all of its crude oil from overseas, is particularly exposed. Over 90% of its crude oil imports come from the Middle East, making a stable supply through the Strait of Hormuz paramount.
Japan’s Energy Dependence and the Rise in Anxiety
Japan relies on thermal power plants for approximately 70% of its electricity generation. The current situation has sparked significant public anxiety, with a recent Asahi Shimbun poll (March 14-15) revealing that 90% of respondents are concerned about the conflict’s impact on the Japanese economy.
Strategic Oil Reserve Release and Regional Cooperation
To mitigate the impact of potential supply shortages, the Japanese government began releasing 30 days’ worth of state-held oil reserves on Thursday, March 26, 2026. This follows a prior release of 15 days’ worth of oil stockpiles by the private sector. Middle Eastern countries, including the United Arab Emirates, are discharging five days’ worth of oil reserves in Japan to support Japanese oil wholesalers.
Broader Implications for Indo-Pacific Security
The conflict’s ramifications extend beyond energy security. The situation is prompting a reassessment of security dynamics in the Indo-Pacific region. Japan’s growing military and technological support is too seen as a boost to the security of Taiwan.
Impact on the Japanese Economy
The disruption to oil supplies and the resulting price increases pose a direct economic risk to Japan. The government has pledged to make “all necessary diplomatic efforts” to minimize the impact on economic activities.
