More Positive Surprise in Japan’s Q1 GDP

How quickly sentiment can change! Six months ago, investors were high on Japan, salivating over its soaring stock market and the prospect of new Prime Minister Sanae Takaichi unleashing fiscal stimulus and fast GDP growth. Now, they seem down in the dumps, preoccupied by debt fear, the flagging yen and the prospect of more rate hikes, all of which folks fear will negate or forestall stimulus, rendering sad GDP. Never mind that Japan is one of the MSCI World’s top-performing countries this year and inches away from pre-war highs—the party, headlines warn, won’t last. We see a big gap between sentiment and reality here, one today’s Q1 GDP report illustrates.

Overall, it was a good report. GDP accelerated from 0.8% annualized in Q4 2025 to 2.1%, driven by consumer spending’s 1.0% growth after a flat Q4 and exports’ 7.1% surge.^[i] Imports, meanwhile, also grew despite the weak yen’s headwinds, showing currency factors aren’t a huge domestic demand headwind. Last November, we wrote that gloom over Japan’s Q3 2025 GDP contraction was overdone—the skewed, illusory decline masked underlying plusses. Q1 is more evidence that thesis was correct.

But most coverage didn’t portray it that way. Echoing attitudes toward Q1 results elsewhere, headlines warned growth will soon be disrupted by the energy crunch and other consequences of the Strait of Hormuz’s closure. Lately, a potential naphtha shortage has dominated Japanese headlines, with warnings of trouble for everything from snack food companies (which need the oil and gas byproduct for colored packaging) to the auto industry (which relies on naphtha for paint and tires, among other inputs). Throw in energy supply concerns, and the consensus view holds that shortages will whack Japan’s heavy industry, leaving the country in desperate need of fiscal stimulus that may not come.

We find that all a bit overwrought. Japan’s energy landscape actually looks ok. While the government’s decision to tap strategic oil reserves sparked fear, this looks like a temporary solution to buy time for the country to find new oil suppliers. That is now happening, with tankers arriving from Azerbaijan. Meanwhile, local power supplier TEPCO has restarted some nuclear plants offline since the Fukushima disaster, and the government relaxed rules on coal power to ease the pressure while natural gas supply routes adjust. And as for the naphtha shortage, producers say it is more about panic buying and hoarding than actual supply chain problems. It should all simmer down soon.

Which leaves a simple question: Does Japan need fiscal stimulus? Q1’s GDP report suggests not. Business investment continued growing, following Q4’s 5.6% annualized growth with 1.1%.^[ii] Residential investment continued its recovery from the sharp Q3 decline caused by a new building code’s taking effect. Construction firms are moving forward. And while government spending and investment also grew, the contribution to headline GDP wasn’t huge. The public sector contributed just 0.3 percentage point of GDP’s 2.1% annualized growth.^[iii] Private domestic demand’s contribution doubled that. Net trade did a lot of heavy lifting, too. And this is all without a big supplementary budget of household and business subsidies. Seems to us Japan’s private sector is growing fine without the extra help.

A summer stimulus package might help at the margins, but we doubt it would be a major boost. Japan has a long history of such stimulus tweaks. They tend to pull some demand forward but don’t deliver lasting acceleration, and the results can disappoint when stimulus hopes are baked in. Today, we see the opposite of that. People see stimulus as both necessary and the straw that might break the Japan debt camel’s back.^[iv] We don’t think it is either (more on Japan’s debt here), which seems like a nice brick in Japan’s wall of worry.
