Nationwide Port Worker Strikes Disrupt Operations Across Japan for the First Time in Six Years

by Mii Tamai | Apr 22, 2025

Port operations across Japan came to a halt as unionized dockworkers launched a nationwide strike, marking the country’s first such industrial action in six years. The workers are demanding higher wages amid rising living costs.

The strikes are being led jointly by the National Council of Dockworkers’ Unions of Japan (Zenkoku-Kowan) and the All Japan Dockworkers’ Union (Zen-Nikkoren), which together represent over 17,000 members employed at ports nationwide.

Japan Port Strike: Negotiations Faltering

According to union representatives, this year’s Shunto (spring labor offensive) negotiations with the Japan Harbor Transportation Association (JHTA) broke down without resolution, and a central bargaining session has not been scheduled following the failure of talks aimed at meeting union demands. The unions had demanded a monthly base pay increase of either ¥30,000 or 10%, as well as a minimum starting salary of ¥220,000. The dissatisfaction of the port workers' unions regarding the content of the employers' revised response to their demands led to the announcement of a strike. The ongoing labor dispute has raised concerns about job security and the potential impact on employment, particularly among casual and permanent workers in the stevedoring industry.

Most recently, a 24-hour strike was held on April 20, halting cargo handling operations at major ports including Tokyo and Yokohama. Previous strike actions also took place on March 30 and April 13, though these primarily fell on Sundays—typically low-volume days for port activity—minimizing disruption. According to Japan’s Ministry of Land, Infrastructure, Transport and Tourism (MLIT), while some delays were reported, there was no widespread impact.

Introduction to the Dispute

The ongoing labor dispute between the dockworkers’ unions and the Japan Harbor Transportation Association (JHTA) that led to the port strike has its roots in the annual Shunto (spring labor offensive) negotiations. These negotiations are a critical time for unions across Japan to push for better wages and working conditions. This year, the dockworkers’ unions have been particularly vocal, demanding a monthly base pay increase of either ¥30,000 or 10%, along with a minimum starting salary of ¥220,000. The JHTA, representing the management side, has been resistant to these demands, leading to a series of strikes and a breakdown in negotiations. The dispute has garnered significant attention due to its potential impact on Japan’s ports, which are vital hubs for international trade.

Causes of the Port Strike

The primary cause of the disruption lies in the stark differences between the union demands and the JHTA’s willingness to meet them. The unions are pushing for substantial wage hikes and improved working conditions, arguing that these changes are necessary to make port labor more attractive and sustainable. On the other hand, the JHTA has expressed concerns about the financial feasibility of meeting these demands, especially in the current economic climate. This deadlock has been exacerbated by a lack of progress in the central bargaining sessions, leading to frustration among the dockworkers. The unions have also criticized the JHTA for not taking their concerns seriously, further straining the relationship between the two parties.

Impact on Global Trade

The labor dispute and strike at Japan’s ports has far-reaching implications for global trade. Japan’s ports, including major ones like Tokyo, Yokohama, and Osaka, are critical nodes in the international shipping network. The strikes have already caused delays in cargo handling, and if the dispute continues, the impact could be even more severe. Shippers and vessels relying on these ports may face significant delays, leading to disruptions in supply chains worldwide. The timing of the strikes, coinciding with Japan’s Golden Week holidays, adds to the risk of congestion and further delays. As the situation unfolds, stakeholders in the global trade community are closely monitoring developments, aware that prolonged disruptions could have a ripple effect on international commerce.

Upcoming Strike Action Schedule:

Although future strike actions are currently planned for weekends when port activity is lower, they overlap with Japan’s Golden Week holidays, increasing the risk of cargo congestion and supply chain disruption. Each strike spans an entire day, significantly impacting port operations. The strikes are set to start at the beginning of the workday, emphasizing the organized approach of the unions.

  • March 30 (Sunday): Completed
  • April 13 (Sun): Completed
  • April 20 (Sun): Completed
  • April 26 (Sat): Scheduled → Cancelled
  • April 27 (Sun): Scheduled
  • May 11 (Sun): Scheduled

Lack of Progress on Union Demands Frustrating Workers

During a recent press conference, Kazuhito Takeuchi, Executive Committee Chairman of Zenkoku-Kowan, stated:

“We have been negotiating to make port labor more attractive, but there has been no progress. Unless meaningful agreements are reached, we will consider further strike actions.” This marks the first strike in six years, highlighting the significance and impact of the action on port operations.

A spokesperson for JHTA commented:

“We’ve been notified that additional strikes may take place. We are committed to labor-management negotiations to minimize any disruption.”

The next round of talks is scheduled for Monday, April 28. While JHTA expressed a desire to avoid further port strikes in Japan, union representatives signaled a shift in negotiation tactics, suggesting they may now approach cargo owner groups directly—not just shipping associations—as part of a broader strategy to achieve fair wage adjustments. This includes submitting formal requests to these groups, jointly with MLIT, and potentially seeking introductions through Japan’s Ministry of Economy, Trade and Industry (METI) and the Ministry of Agriculture, Forestry and Fisheries (MAFF).

The unions appear to acknowledge this new approach, though tensions remain. If negotiations fail to yield concrete results, strikes may not only continue on May 11, but could also be expanded to weekdays, causing greater disruption to Japan’s domestic and international logistics networks. The upcoming talk on April 28 prior to fifth round of negotiations will be crucial in determining the next steps.

Industry stakeholders are advised to closely monitor the situation as developments unfold. The national federation's involvement in organizing strike actions and responding to negotiations underscores the broader conflict with management.
