Does Japan Have a Labour Shortage?
The notion that Japan has a labour shortage is widely accepted. The country's ageing and shrinking population leaves fewer working-age people for firms to hire. Businesses often cite difficulties finding workers as a reason for raising pay, and labour shortages are seen as a driver of inflation. However, Mizuho executive economist Momma Kazuo, in a commentary published on 21 January 2025, challenges this view. He argues that labour market conditions are more nuanced than commonly perceived and that declining real wages contradict the narrative of a general labour shortage. This post summarises key points from the report.

Nominal wages are increasing
- The 2024 shunto spring wage negotiations produced a 5.1% nominal pay gain, the highest in 33 years. Labour unions are aiming for a 5%+ increase in 2025.
- Inflation and labour shortages are widely cited as drivers of wage increases. While inflation is a clear driver of wage gains, the impact of labour shortages is less certain.
- Businesses cite pay increases as necessary to retain workers. But if labour shortages were driving inflation, nominal pay gains would outpace inflation and real wages would rise.
- Real wages briefly increased in summer 2024 but remain 2.4% lower than in 2019.
- To recover this loss by 2026, real wages need to rise 1.2% annually, which requires nominal pay gains of 3.2% assuming 2% inflation. This aligns with shunto outcomes of 5%.
- The modest union wage demands suggest limited negotiating power. True labour shortages would lead to stronger wage demands.
2017 again?
- In 2017, wage stagnation was partly attributed to increased employment of women and seniors, who often take lower-wage jobs, reducing average wage levels.
- Workforce growth from these groups has since slowed, leading some to argue that current wage increases reflect genuine labour shortages.
- But the continued stagnation of real wages casts doubt on this argument. It also suggests that wage stagnation in 2017 has yet to be fully explained.
Not really a labour shortage?
- Some researchers argue that labour shortages are overstated, including Professor Saito Makoto of Nagoya University and Professor Shioji Etsuro of Chuo University.
- Indicators like the job-to-applicant ratio, the unemployment rate, and the Bank of Japan's labour supply-demand gap estimate show that the labour market is not as tight as before the pandemic.
- Labour shortages may be sector-specific, with industries like IT, construction, and essential services facing shortages, while others, such as office roles, experience surplus supply.
Financial constraints impeding wage growth
- Businesses may lack the financial resources to support significant wage increases.
- Japan's real GDP growth has been so weak as to suggest that Japan is heading towards four lost decades.
- Weak real GDP growth and worsening terms of trade have eroded Japan's real Gross Domestic Income (GDI), with ¥5.8 trillion (approximately 1% of GDP) in income flowing out of the economy since 2019.
- This weak macroeconomic environment limits the ability to achieve sustained real wage growth.
Domestic growth expectations are key
- Many businesses increasingly rely on price increases to fund wage hikes, but this does not improve real wages as higher costs offset nominal gains.
- Policies to sustainably increase real wages are difficult to identify, but obstacles that need to be resolved include institutional constraints, time and cost barriers to reskilling, a lack of investment in workers, and weak domestic growth expectations.
