Japan's Labor Law Reform: Dismissal Rules, Labor Mobility, and the Fight Over Productivity
Japan's labor law reform debate, dismissal rules, regular vs. non-regular employment, labor mobility, and what it means for public affairs and corporate strategy in Japan.
Japan’s labor market is simultaneously tight, rigid, and bifurcated, and policymakers have been trying to reform it for more than a decade. The late-2024 LDP and CDP leadership races put labor law reform squarely back on the national agenda, and the issue has continued to move through the Diet and the ministries as of 2026. For foreign and domestic firms operating in Japan, the outcome will reshape hiring, severance, wages, and the cost of restructuring.
Understanding the debate is essential for corporate affairs teams navigating public policy in Japan because labor rules touch every operating company: not just HR, but procurement, M&A, and strategic planning.
Why labor reform is back on the agenda
Labor-market reform has long been cited as one of the few remaining structural levers to lift Japanese productivity. The original wave under former Prime Minister Shinzo Abe, the “work-style reform” pillar of Abenomics, delivered statutory overtime caps, mandated paid leave, and the “equal pay for equal work” principle between regular and non-regular employees. Those rules were consolidated through legislation passed between 2018 and 2020.
The current debate has shifted focus. Rather than limiting excess work, the argument is now about whether to ease the legal hurdles to dismissing permanent employees, to increase labor mobility, and to close the structural wage gap between regular and non-regular workers. Proponents see this as the next frontier in raising wages; opponents see it as eroding worker protection.
‘Regular’ vs. ‘non-regular’ workers: the core structural issue
Japan’s labor market is defined by a deep split between seishain (regular employees) on indefinite contracts and hiseiki (non-regular) workers on fixed-term or part-time contracts.
- Regular employees enjoy strong de facto protection against dismissal under Article 16 of the Labor Contract Act and decades of case law, along with seniority-based pay, retirement benefits, and career-long training.
- Non-regular employees, who make up roughly 37% of the workforce, earn less per hour, receive fewer benefits, and carry most of the adjustment burden during downturns.
The entrenched difficulty of dismissing regular employees shapes hiring behaviour profoundly. Firms are cautious about adding permanent headcount, rely on new-graduate hiring to fill core roles, and use non-regular employment as a shock absorber. The result is low job mobility, wage stagnation, and a labor market that struggles to reallocate talent toward growth sectors.
The case for easing dismissal rules
Reform proponents argue that loosening dismissal restrictions would raise labor mobility and productivity. If firms can more readily restructure, they will also hire more confidently, particularly mid-career workers who currently struggle to move between companies. Workers would be incentivised to move to higher-paying jobs, which would in turn pressure employers to compete harder to retain talent and push wages upward.
This argument is ultimately about wage inflation, which the Bank of Japan has been trying to engineer for more than a decade. Without meaningful job-switching, it is hard to generate sustained wage pressure outside of organised annual shunto wage negotiations.
The case against
Opponents (including most of organised labor, the CDP, and several LDP members) argue that weakening dismissal rules risks shifting adjustment costs onto workers without delivering the promised productivity gains. In a country with weak unemployment insurance relative to many OECD peers, dismissal liberalisation could translate into income insecurity more than into mobility.
Organised labor, represented most prominently by Rengo (the Japanese Trade Union Confederation), has consistently opposed compensated-dismissal schemes and pushed instead for stronger non-regular worker protections and higher minimum wages.
Political positions going into 2024–2025
The 2024 LDP leadership race surfaced a clear split within the party. Shinjiro Koizumi, briefly the frontrunner, explicitly endorsed easing dismissal restrictions and said he would “decisively implement regulatory reforms, including labor market reforms, with no regard to issues considered off-limits.” Katsunobu Kato and Taro Kono voiced varying degrees of support for raising labor mobility.
Other contenders (Shigeru Ishiba, Toshimitsu Motegi, and Yoshimasa Hayashi) either deferred or prioritised other reforms. Sanae Takaichi, who eventually secured the premiership in 2025, was vocally opposed to easing dismissal restrictions.
The CDP went into its own leadership race broadly opposing dismissal liberalisation. Its 2022 platform called for employment to be “permanent, direct, and full-time,” and all of its leadership candidates voiced support for stable employment.
What has moved, and what hasn’t, under coalition politics
Under minority-government conditions from late 2024 onward, sweeping labor reform proved politically difficult. Any legislation touching dismissal rules requires coalition-building across parties with conflicting positions, and organised labor’s influence runs across both the LDP and the opposition.
More incremental measures have moved forward. Reforms to re-skilling and mid-career transition support, expanded portability of retirement benefits, and tweaks to fixed-term contract rules have progressed through MHLW working groups. The “1.03 million yen wall” negotiated during the 2024 extraordinary Diet session addressed a tax-and-labor distortion that suppressed part-time hours. But the core legal protections around dismissing regular employees remain largely intact as of 2026.
The political economy of reform
Any prime minister willing to meaningfully change dismissal rules will need significant political capital and a clear electoral mandate. Japan’s vested interests (organised labor, business federations with competing priorities, and internal LDP constituencies) all have levers to slow or redirect reform.
Keidanren, Japan’s largest business federation, has repeatedly emphasised that energy policy and economic security take priority over labor reform in its engagement with the government. That posture limits the political oxygen available for dismissal liberalisation, even among business-aligned LDP factions.
The arithmetic also matters. Under coalition conditions, any labor reform bill would need to survive CDP and DPP scrutiny in the Diet, and committee chairmanships now held by the opposition give them meaningful procedural leverage.
What this means for companies operating in Japan
For multinationals and domestic firms alike, the implication is that labor law reform will remain incremental rather than transformational. Practical planning should reflect that reality.
- Restructuring timelines in Japan remain long. Business reorganisations, M&A integration, and headcount adjustments should assume the existing legal and case-law framework around dismissals.
- Labor mobility is increasing from the worker side, slowly. Mid-career hiring is growing as a share of total recruitment, particularly in technology and professional services. Employer value proposition, retention practices, and internal mobility are all increasingly important.
- Non-regular employment rules are being reshaped around the edges. Changes to “equal pay for equal work” enforcement, dispatch-worker rules, and short-hour thresholds all have operational consequences.
- Engagement matters. The scope and pace of future reform will be shaped in MHLW advisory councils, Diet committees, and tripartite labor-management-government forums. Firms with significant Japan exposure benefit from visibility into those discussions.
Why this matters for public affairs in Japan
Labor law reform is one of the slowest-moving and most politically sensitive areas of public policy in Japan, and precisely because of that, it is often where durable commercial risk sits for foreign firms. Dismissal rules, dispatch regulations, and non-regular employment standards shape the economics of Japan operations in ways that HR policy alone cannot absorb.
