Japan’s Economy Recovered In Second Half But Barely Grew in 2024

For decades in Japan, it was accepted as gospel: A weak currency makes companies more competitive and bolsters the economy.

Part of that promise came true last year: As the yen tumbled to a 37-year low against the dollar, big brands like Toyota Motor reported the highest profits in Japanese history. Stocks soared to record highs.

Yet for the majority of Japanese households, the weakened yen has done little more than drive up the costs of basic living expenses, such as food and electricity. Figures released Monday showed that while Japan’s economy picked up pace in the second half of 2024, its inflation-adjusted growth rate for the full year slowed to 0.1 percent. That was down from 1.5 percent the prior year.

Attempting to stimulate exports by weakening a currency has long been a policy tool for countries seeking economic growth: President Trump has said he wants a weaker dollar to help American manufacturing. Japan provides an example of what can happen when a depreciated currency, even if it helps exports, crushes consumer purchasing power by worsening inflation.

“In economics, they teach us that everything has a benefit and a cost, and it’s about asking which is greater,” said Richard Katz, an economist who focuses on Japan. Of the yen trading at around 153 to the dollar, “this is clearly not the way to run a railroad,” Mr. Katz said. “It would be good to take a lesson from this.”

The figures released on Monday show that household spending shrank slightly in 2024, after expanding in the previous three years. Unlike in the United States, where strong consumption helped the economy surge back after the Covid-19 pandemic, prolonged weak spending in Japan has left its real gross domestic product barely above prepandemic levels.
