🧮 A government just promised to pour ¥370 trillion (about $2.3 trillion, more than half the country's yearly GDP) into "growth." The headline number is gigantic. The genuinely funny part is everything the announcement left blank.

On June 24, the Japanese government rolled out a roadmap for the flagship economic policy of Prime Minister Sanae Takaichi: 17 "strategic sectors," a combined public-and-private investment target of over ¥370 trillion by fiscal 2040, with semiconductors getting the single largest slice. Read past the big number, though, and the document reads less like a plan and more like a wish list with a calculator attached.

A number larger than half the economy

The government set the total at more than ¥370 trillion (around $2.3 trillion) to be invested across the 17 fields by 2040, framing it as the engine of Takaichi's "responsible expansionary fiscal policy." Chips are the headline item, slated for ¥68 trillion (about $420 billion) as a matter of economic security.

To put ¥370 trillion in perspective: economist Takahide Kiuchi of Nomura Research Institute pegs it at roughly 56% of Japan's 2025 nominal GDP, redirected toward whatever the government has decided is the future.

The 6.5x return economists would love to believe

The roadmap doesn't just list spending. It lists the "economic ripple effects" that spending is supposed to generate. This is where the calculator starts to smoke.

Sector Investment Claimed ripple effect Multiplier
Semiconductors ¥68T (~$420B) ¥443.3T (~$2.7T) ~6.5x
Data centers (by FY2035) ¥32.7T (~$200B) ¥107.1T (~$660B) ~3.3x

A 6.5x return on chips is the kind of number that, if it were real and bankable, would mean you shouldn't be buying government bonds; you should be buying the Ministry of Economy. Official "ripple effect" figures are produced by running input-output tables at full throttle. They are theoretical ceilings, not what lands in anyone's bank account. Presenting them next to the spending, with no error bars, is a bit like advertising a casino by its best night.

The blank where the answer should be

Tucked into the same announcement is the detail that undoes a lot of the confidence: the government has not said how much of the ¥370 trillion it will actually pay, or how the total splits between public money and private money.

So the structure is: a $2.3 trillion plan, payer to be determined. When an individual decides to "just throw money at it," they at least know the size of their own wallet. Here, the wallet is a national mystery, and that matters: the entire mechanism depends on it. If the public share is small and private money does the heavy lifting, great, efficient. If the private money never shows up, the plan is what Kiuchi bluntly calls a picture of a rice cake: nice to look at, impossible to eat. And if the government ends up footing a large bill instead, the country gets more debt rather than more growth.

When everything is strategic, nothing is

The 17 fields are subdivided into 62 priority products and technologies. The list is genuinely sprawling: AI and semiconductors, quantum, fusion, synthetic biology, aerospace, drug discovery. And then also shipbuilding, ports and logistics, and video games, which alone get ¥24.5 trillion (about $150 billion).

Kiuchi's word for the lineup is sōkateki: scattershot, a little of everything. His complaint isn't that any single item is wrong, but that the package has no grand design: stitch 17 separate industrial policies together and you still can't see what Japanese economy is supposed to exist at the end of it. A strategy in which everything is a top priority is a strategy in which nothing is.

The double-counting problem

Here is Kiuchi's sharpest point, and the one that should make a reader squint. Some of this ¥370 trillion may already be spoken for. A separate public-private green-transformation (GX) program already commits roughly ¥150 trillion over ten years to solar, hydrogen, EVs, batteries, and chips, all of which sit comfortably inside these 17 fields. On top of that, a good chunk of the "private investment" being counted is likely spending companies had already planned to make regardless.

Add it up and the ¥370 trillion may be, in part, the same yen counted twice and dressed for a bigger occasion. A headline total assembled this way will always look impressive, because it is partly a sum of things that were going to happen anyway.

The deadline, conveniently 14 years out

And now the most elegant design choice of all: the target date is fiscal 2040. Far enough away that essentially no one announcing the figure today will still be in the job when the results come due. Your money turns up on next month's statement. This one gets its answer key graded in 2040.

To be fair, the underlying instinct isn't crazy. Takaichi told the meeting she wants to break what she called a cycle of excessive austerity and underinvestment in the future, and economic-security industrial policy is now standard issue worldwide: the US CHIPS Act, the EU Chips Act, and the equivalents in Korea, Taiwan, and China all run on the same logic. When export controls can throttle your supply of critical goods, building capacity at home has a real rationale. And ¥370 trillion was never billed as government cash alone; it is an all-in public-plus-private headline.

The trouble is the distance between "we will catalyze ¥370 trillion of investment" and "here is who pays, here is the genuinely new money, and here is how we will know it worked." That gap is exactly where plans like this tend to lie down for a long nap.

So, what's the round number in your country?

Every government keeps a favorite enormous round number in a drawer: a trillion here for green energy, a few hundred billion there for chips, always with a deadline set safely beyond the next election. Japan's just happens to be a particularly tidy ¥370 trillion. When your own government last announced one of these, did anyone ever check the receipt, and did the money turn out to be new, or simply the old money wearing a bigger hat?
