<\/div>\n

Tensions surrounding the Strait of Hormuz<\/strong> have been growing as the conflict between Israel and Iran has progressed. This spiked in June 2025 after Iranian missiles struck a U.S. base in Qatar, prompting fears that Tehran might seal the channel that funnels roughly<\/a> 20 million barrels a day of crude oil and one-fifth of the world\u2019s LNG.<\/strong><\/p>\n\n\n\n

Markets quickly remembered that Japan, which still gets<\/a> 85% of its primary energy from fossil fuels, sits at the very front of the collateral damage queue. Understanding why this is the case illuminates both the scale of the risk and the potential escape route.<\/p>\n\n\n\n

The Strait of Hormuz: A Global Energy Choke Point<\/strong><\/h2>\n\n\n\n

In 2024, 84% of the crude oil and 83% of the LNG that left the Persian Gulf sailed through the Strait of Hormuz to Asia. Just four customers<\/a> \u2014 China, India, Japan and South Korea \u2014 accounted for 75% of the oil and 59% of the LNG.<\/p>\n\n\n\n

The choke point risk is amplified by geography: Hormuz\u2019s shipping lanes are only 2 miles (3.2 km) wide<\/a> in each direction and surrounded by Iranian territory on three sides. This makes Asia uniquely exposed as even a brief blockade can create a point of failure for Asian energy security.<\/p>\n\n\n\n

Iran Threatened to Close the Strait of Hormuz<\/strong><\/h2>\n\n\n\n

Iran has repeatedly threatened to \u201cclose the Strait of Hormuz,\u201d and U.S. intelligence reported<\/a> that the Iranian military loaded naval mines onto ships in late June 2025. Although the mines have not been placed, the act represented a serious escalation towards closing the Strait.<\/p>\n\n\n\n

New modelling by Zero Carbon Analytics warns that a complete shutdown could drive Brent crude<\/a> to about USD 130 per barrel, up from the low USD 60 per barrel in early June 2025 and matching the 2008 oil shock. On the more extreme side, Iraq\u2019s deputy prime minister floated an extreme USD 300 per barrel price. While JPMorgan analysts place the severe-outcome band at up to USD 130<\/a>, the repercussions would extend well beyond just energy costs, likely impacting global economic growth and inflation.<\/p>\n\n\n\n

LNG prices in Asia move roughly in tandem<\/a> with oil, so the Japan Korea Marker would likely double or triple in the same scenario.<\/p>\n\n\n\n

Japan\u2019s Heavy Reliance on Hormuz-linked Fuels<\/strong><\/h2>\n\n\n\n

Japan imports<\/a> approximately 87% of its total primary energy supply, and fossil fuels still generate over 60% of its electricity, one of the highest dependency ratios<\/a> among OECD countries. Such heavy reliance means that any disruption to Gulf shipping would reverberate directly through Japan\u2019s economy, a vulnerability that is the most acute among major Asian importers.<\/p>\n\n\n\n

Crude Oil Exposure<\/strong><\/h3>\n\n\n\n

Japan buys virtually all of its oil from the Middle East. The IEA calculated that approximately 80%<\/a> of Japan’s crude imports transited the Strait in 2018. The share is likely little changed today because Saudi Arabia, the UAE and Kuwait remain Tokyo\u2019s top suppliers<\/a>.<\/p>\n\n\n\n

This is a unique level of exposure among Asian countries<\/a>. South Korea\u2019s exposure is lower, at 68%, while India\u2019s is lower still, at 53%, and China’s is the lowest, at 15%. One of the primary reasons for this is that Japan has no overland pipelines and limited domestic production to soften the blow.<\/p>\n\n\n\n

LNG Dependency<\/strong><\/h3>\n\n\n\n

While Japan has diversified its LNG imports since the Fukushima disaster, the Middle East still supplied<\/a> roughly 10% of Japan’s cargoes in 2022, most of which must sail through the Strait of Hormuz. Utilities such as JERA and Kyushu Electric held long-term Qatari contracts that expired in 2021 and are now negotiating<\/a> replacements even as tensions flare. Unlike crude, LNG cannot be easily rerouted because Q-Max tankers require specialised ports, so even modest Gulf exposure matters during a crisis.<\/p>\n\n\n\n

Economic Shock Channels for Japan<\/strong><\/h2>\n\n\n\n

A sustained USD 120 to 130 oil price would increase Japan\u2019s import bill and widen its trade deficit, putting fresh downward pressure on the yen and complicating the Bank of Japan\u2019s efforts to combat inflation. Predictions indicate that this would push the Japanese economy<\/a> into stagflation, resulting in a 0.6% lower GDP than expected for 2026.<\/p>\n\n\n\n

Power markets are vulnerable too: as spot LNG prices increase, so do domestic electricity prices. This adds more strain to the economy and increases annual generation costs by tens of billions of yen. With the recent 2022 Russia-Ukraine conflict-related LNG price spike<\/a> still at the forefront of the minds of many, there are several signs that fossil fuel price volatility will continue to increase.<\/p>\n\n\n\n

Strategic Response Options<\/strong><\/h2>\n\n\n\n

Short-term Shock Absorbers<\/strong><\/h3>\n\n\n\n

Japan maintains government and industry stockpiles<\/a> equal to about 180 days of crude demand.  This can help fill demand, particularly if it is efficiently distributed and allows Japan to look for alternative importers. However, if a blockade extends beyond 180 days, it would be nearly impossible for Japan to fill the supply gap with other importers completely.<\/p>\n\n\n\n

Long-term Resilience: Renewables First, Lessons From Europe<\/strong><\/h3>\n\n\n\n

Japan is not short of domestic clean-energy resources. The country has a technical potential<\/a> for more than 2,000 GW of solar PV and around 1,000 GW of wind, which are enough to cover current electricity demand more than 10 times over. Tapping even a fraction of that capacity would drastically improve the country\u2019s energy security.<\/p>\n\n\n\n

Domestic renewables also hedge commodity-price shocks. Once built, solar and wind provide zero-fuel-cost electricity, shielding households and industry from the volatility that a Strait of Hormuz crisis would create.<\/p>\n\n\n\n

Europe offers a recent playbook. After Russia\u2019s 2022 invasion of Ukraine, EU governments fast-tracked<\/a> wind, solar and efficiency measures that helped drive an 18% drop<\/a> in natural gas consumption by 2023. This helped keep storage full and wholesale prices in check despite collapsing pipeline inflows from Russia.<\/p>\n\n\n\n

Beyond the Strait: Securing Japan\u2019s Energy Future<\/strong><\/h2>\n\n\n\n

The Strait of Hormuz risk triangle \u2014 geographic choke point, geopolitical conflict and near-total fossil dependence \u2014 puts Japan at risk during any Gulf crisis. The country\u2019s post-Fukushima stall<\/a> on renewables has deepened that exposure, but on the flip side, there is opportunity.<\/p>\n\n\n\n

Decisive investment in wind, solar and electrification could slash fossil fuel imports before 2030, transforming today\u2019s liability into a competitive, low-carbon edge for the world\u2019s third-largest economy.<\/p>\n","protected":false},"excerpt":{"rendered":"
