Sanae Takaichi's 370 Trillion Yen Plan to Boost Japan's Economy

Sanae Takaichi, Japan's first female Prime Minister, is pursuing an ambitious and radically different plan to elevate Japan's economic standing. Her vision aims for Japan to stand "shoulder to shoulder with other major economies," proposing a 370 trillion yen investment by 2040 across various sectors, including chips, AI, defense, food tech, and content creation like manga. This plan unfolds against a challenging backdrop of high national debt, demographic decline, strained relations with China, and persistent cost-of-living concerns.

The Woman Behind the Plan

Born in Nara, Japan's ancient capital, Takaichi is described as an "ordinary person" from a normal mid-income family, distinguishing her from many Japanese politicians who come from established political dynasties. In her youth, she exhibited a rebellious side, notably enjoying heavy metal drumming.

Her ascent to the leadership of the long-ruling Liberal Democratic Party (LDP) came at a time when the party was struggling after recent electoral defeats. Takaichi successfully tapped into right-wing sentiment, particularly on immigration issues, drawing support away from emerging right-wing parties. Her initial popularity was immense, leading to an election landslide and a wide array of merchandise, from keyrings to cookies. While her approval ratings have seen a slow but steady decline, she remains significantly more popular than her male predecessors.

A Historic but Socially Conservative Leader

Takaichi's premiership marks a historic milestone as Japan's first female Prime Minister, a significant achievement in a country where female representation in politics is only 14%, compared to a global average of 30%. However, her politics are socially conservative. She opposes legalizing same-sex marriage and allowing married couples to retain separate legal surnames, positions that appeal to conservative voters within the LDP.

Economic Challenges and the Cost of Living Crisis

Despite her popularity, Takaichi faces an electorate deeply concerned about the cost of living. The Japanese yen has significantly weakened, with one dollar buying over 160 yen in July 2026, near its weakest level in four decades. This makes imports, particularly food and energy, expensive, fueling inflation for households and businesses. Japan's heavy reliance on Middle Eastern oil makes it vulnerable to rising oil prices, exacerbated by global conflicts like the US-Israel war with Iran, which has driven up costs across the board.

Japan is unaccustomed to inflation, having experienced three decades of flat prices, weak wage growth, and ultra-low borrowing costs. The recent return of persistent inflation has created significant struggles for the population. The weak yen has also led to an influx of foreign tourists, causing social problems related to overcrowding and occasional poor behavior.

Demographic Decline and Immigration Stance

A deeper demographic issue for Japan is its shrinking and aging population, with deaths outnumbering births and a centenarian population exceeding six figures. While longevity is positive, funding it with a shrinking workforce is challenging. Despite the need for more foreign workers, Takaichi has tightened immigration rules and promised tougher enforcement, a stance that contrasts with the country's demographic realities.

Takaichi's Governance Style and Policies

Takaichi's governance style differs from her predecessors. She has met with ministry officials less frequently and conducts fewer media interviews, primarily using social media to communicate.

Her key policy actions include: - Subsidizing gasoline and energy prices over the summer. - Diversifying Japan's oil supply. - Pledging to cut consumption tax on food and soft drinks from 8% to 1% for two years, starting April 2027. This plan, however, raises concerns about mounting government debt. - A 370 trillion yen investment plan (public and private) over 14 years to grow Japan's economy. This targets 17 crucial sectors, including AI, defense, energy, semiconductors, food tech, and content creation (manga/anime). The goal is to create a stronger Japan with sturdier supply chains and a more capable economic and security partner in Asia.

Defense and Foreign Relations

Takaichi is also looking to overhaul defense guidelines amidst growing challenges from China, North Korea, and Russia. Her assertion that a war over Taiwan would be an "existential threat" for Japan drew a strong reaction from China, Japan's biggest trading partner. Despite a diplomatic campaign by China to isolate her, Takaichi has refused to retract her statements, a more assertive stance than previous prime ministers.

Japan's defense spending, historically around 1% of GDP, increased to about 2% under former Prime Minister Kishida in 2022. Takaichi aims to push this even further, a move that has pleased figures like former US President Trump, who has long advocated for allies to increase their defense spending. Takaichi has actively cultivated a good relationship with Trump, though this has drawn some domestic criticism for being overly eager to impress him.

Concerns about the yen's undervaluation led to a coordinated intervention in the currency market by Japan and the US Treasury, the first in about 15 years, to boost the yen. US Treasury Secretary Scott Bessent indicated a willingness to intervene again if necessary. Given Japan's substantial holdings of US government debt and its role as a major pool of global capital, yen movements have far-reaching international implications.

The Debt Challenge

The 370 trillion yen investment plan is a target for both public and private investment, raising questions about the source of public funds. The government will likely need to issue extra bonds, which could create further pressure given Japan's government debt is more than twice the size of its economy—the highest among G10 nations. While the debt-to-GDP ratio has recently lowered due to a "normalization phase" after pandemic spending, servicing this debt still consumes about a fifth of Japan's annual budget. The success of Takaichi's project is crucial, as failure could impose a huge burden on Japan's public finances.

Outlook

Takaichi's main challenges include ensuring the success of her economic program, gaining market confidence, reviving the economy amidst a declining population, and managing the increasingly difficult relationship with China. Despite lacking a solid base of support within the ruling party, her power is bolstered by public popularity. People have reacted positively to her economic policies, expressing more hope than in previous years. With this mandate, Takaichi is committed to making her vision work, with the ultimate test being whether her "stronger Japan" will also prove to be a richer and safer one in the years to come.
