Japan's political landscape is shifting as Prime Minister Sanae Takaichi's cabinet faces its most challenging period yet. Recent opinion polls reveal a sharp decline in public support, with approval ratings plummeting to levels not seen since she assumed office in late 2025. A Mainichi Shimbun survey indicated support dipping to 58 percent in late March, while other polls from NHK and Kyodo News place it between 61 and 63.8 percent in early April, marking record lows amid mounting concerns over the ongoing Iran crisis and its ripple effects on the economy.
This plunge comes after an initial 'honeymoon' phase where Takaichi enjoyed approval ratings soaring above 70 percent following her landslide victory in the February 2026 snap general election. The Liberal Democratic Party (LDP), under her leadership, secured a supermajority in the House of Representatives, cementing her position as Japan's first female prime minister. However, escalating global tensions and domestic economic pressures have eroded that goodwill, testing her administration's resilience.
The Rise of Sanae Takaichi: From LDP Stalwart to Prime Minister
Sanae Takaichi's ascent to power was nothing short of historic. A long-time LDP member known for her conservative views on national security, constitutional revision, and economic reform, Takaichi entered the political spotlight as a key figure in former Prime Minister Shinzo Abe's faction. Her tenure as Minister of Economic Security and other roles honed her reputation as a pragmatic yet firm leader.
In October 2025, amid party scandals and leadership vacuum, Takaichi won the LDP presidency, propelling her to the premiership. She dissolved the lower house shortly after, calling a snap election on February 8, 2026. Campaigning on tax cuts, subsidies for households, and a bold fiscal expansion to combat deflation, her party triumphed, winning over 300 seats. Post-election polls showed approval nearing 80 percent, fueled by optimism for her 'Sanae-mania' appeal and promises of revitalizing Japan's stagnant economy.
Yet, this euphoria was short-lived. By March, cracks appeared as international events overtook domestic agendas.
Unpacking the Iran Crisis: Timeline and Global Ramifications
The catalyst for the approval slide is the intensifying US-Iran conflict, which erupted in early March 2026. Tensions boiled over when the United States and Israel launched joint strikes on Iranian nuclear facilities to prevent weapon development. Iran retaliated by imposing a de facto blockade on the Strait of Hormuz, a chokepoint through which 20 percent of global oil flows, including nearly 90 percent of Japan's crude imports.
Oil prices skyrocketed above $100 per barrel, triggering supply shortages, inflation spikes, and fears of stagflation in energy-import-dependent Japan. Brent crude surges disrupted everything from gasoline prices to manufacturing inputs, with Japanese firms reporting production halts and rising costs. The International Energy Agency noted this as the fastest oil price escalation in decades.
Takaichi's response emphasized diplomacy. She held summits with US President Donald Trump on March 19, urging restraint and Hormuz security. Subsequent calls with Iranian President Masoud Pezeshkian and support for Pakistan's mediation efforts highlighted Japan's neutral stance, constrained by its pacifist constitution and public aversion to military entanglement.
Economic Fallout: Oil Shock Hits Japanese Households and Businesses
Japan's vulnerability to Middle East instability is acute. Prior to the crisis, the nation stockpiled 240 days of oil reserves, but the blockade strained supplies. Gasoline prices jumped 30 percent, food and utility costs followed suit, eroding real wages already squeezed by yen weakness.
Household surveys reveal widespread anxiety: 78 percent express concern over daily life impacts, per NHK polling. Businesses face a double whammy—higher energy costs and disrupted supply chains for petrochemicals and fertilizers. Automakers like Toyota idled plants, while airlines hiked fares amid fuel surcharges. The Bank of Japan delayed rate hikes, complicating its inflation-targeting mandate.
- Oil import costs up 40 percent year-on-year.
- Core CPI inflation projected at 3.5 percent for FY2026.
- SMEs reporting 25 percent cost increases, threatening layoffs.
Government countermeasures include releasing 45 days of strategic reserves, procuring alternative routes via Russia and Australia, and a $10 billion aid package for Asian partners to stabilize regional energy markets.
Public Sentiment: Discontent Brews Over Crisis Management
Polls underscore frustration with the cabinet's handling. A Kyodo News survey found 49.3 percent dissatisfied with oil supply measures, while Mainichi reported 49 percent opposing Self-Defense Forces (SDF) dispatch to the Middle East, even post-ceasefire. Over 70 percent reject US-led attacks on Iran, prioritizing diplomacy.
Reasons for disapproval include perceived policy ineffectiveness (33 percent, NHK) and lack of trust in Takaichi (28 percent). Younger voters and independents, key to her election win, show sharper drops, citing economic pain over foreign policy boldness.
Government's Multifaceted Response: Diplomacy, Reserves, and Fiscal Stimulus
Takaichi's administration has rolled out a comprehensive toolkit. Beyond oil releases, it convened all ministers for supply chain reviews, targeting medical equipment and daily goods. Fiscal measures include subsidies for fuel and electricity, expanded child allowances, and ¥20 trillion supplementary budget for crisis mitigation.
Diplomatically, Japan backs UN resolutions for de-escalation, coordinates with G7 on sanctions, and leverages historical ties with Iran—Japan's third-largest oil supplier pre-crisis. A recent two-week US-Iran ceasefire offers breathing room, with Takaichi pushing for extension.
Opposition Critique and Expert Perspectives
Opposition parties like the Constitutional Democratic Party accuse the cabinet of complacency, demanding energy rationing and faster diversification. CDP leader questions fiscal expansion's sustainability amid ballooning debt.
Experts are divided. Economist Koichi Hamada praises diplomatic agility, avoiding military pitfalls, but warns prolonged crisis could shave 2 percent off GDP. Security analyst Narushige Michishita notes public pacifism limits options, urging long-term LNG pivots.
Polling trends show volatility: from 79 percent peak in January to mid-50s now, per aggregated data. Gift catalog scandals and Diet gridlock compound issues.
Domestic Policies Under Strain: Inflation, Budget, and Reforms
Beyond Iran, inflation at 2.8 percent challenges Takaichi's growth agenda. Her 'fiscal activism'—tax cuts, infrastructure—boosted initial support but draws deficit hawks' ire. The FY2026 budget passed amid protests, prioritizing defense (up 19 percent GDP share) and welfare.
Constitutional revision pushes, core to her platform, stall as crisis dominates headlines. Gender equality initiatives, leveraging her milestone, gain traction but face backlash over work-life policies amid rising costs.
Stakeholder Views: Businesses, Labor, and Citizens
Keidanren (business federation) lauds supply efforts but seeks tax relief extensions. Labor unions demand wage hikes outpacing inflation. Citizens' forums highlight rural vulnerabilities, where fuel costs hit harder.
- Urban salarymen: "Prices up, wages stagnant—need real relief."
- Farmers: "Fertilizer shortages threaten harvests."
- SMEs: "Survival mode; govt aid too slow."
Future Outlook: Can Takaichi Turn the Tide?
With a ceasefire holding tenuously, oil stabilization could rebound approval. Upcoming summits and budget execution offer pivots. Yet, if Hormuz remains choked or recession bites, pressure mounts for cabinet reshuffle or early election.
Takaichi's resilience—navigating scandals and wins—suggests adaptability. Success hinges on balancing security hawks, economic doves, and public pragmatism. Japan's democracy watches closely as its trailblazing leader confronts unprecedented headwinds.
