A European technology company had established a Tokyo subsidiary and hired a senior manager under a local employment contract. When the business unit was restructured, the company issued a dismissal notice without following the procedural steps required under Japanese employment legislation. The dismissed employee – a Japanese national with significant tenure – filed a claim challenging the termination's validity. The client, unfamiliar with Japan's stringent dismissal rules, faced the prospect of reinstatement orders and back-pay liability if the matter proceeded to rodo shinpan (labour tribunal) or full civil litigation.
Employment disputes in Japan are governed by labour legislation that imposes strict conditions on dismissal, requiring objective and socially reasonable grounds. A termination procedure that fails those conditions may be declared void by a labour tribunal or civil court. The process from claim filing to resolution typically spans three to twelve months, depending on whether the matter settles at the labour tribunal stage or advances to civil proceedings.
This case study traces the strategy adopted, the milestones reached, the complications encountered, and the transferable lessons that apply to any international employer managing workforce matters in Japan.
Client profile and the challenge
The client was a mid-sized European technology group operating across several Asian markets. Its Tokyo subsidiary employed approximately forty people. The restructuring eliminated the senior manager's role entirely. The company believed a redundancy-based dismissal was straightforward. In practice, Japanese employment legislation sets a high bar. Courts apply a four-factor test to assess whether a redundancy dismissal is valid. That test examines the genuine necessity of workforce reduction, whether alternatives to dismissal were explored, whether the selection of employees was reasonable, and whether adequate consultation was conducted.
The client had satisfied none of the four factors in a documented way. No written records of alternatives-exploration existed. The collective agreement with the company's employee representative had not been consulted. The dismissal notice period given was also shorter than the statutory minimum. The employee's legal representative filed a claim with the local rodo iinkai (labour relations commission) within weeks of the dismissal, demanding reinstatement and full back-pay.
Legal strategy and rationale
The immediate priority was to assess whether the termination procedure could withstand scrutiny under Japan's labour legislation. The answer was that it could not – at least not without supplementary evidence. The strategy had two tracks running in parallel.
The first track focused on documentation. The team reconstructed the business rationale for the restructuring. Internal communications, financial projections, and organisational charts were collated to establish the genuine necessity of the reduction in force. This evidence would be essential if the matter proceeded to formal hearings.
The second track opened settlement negotiations. Japanese labour dispute resolution strongly favours consensual resolution. The labour tribunal system is specifically designed to produce a settlement within three hearings, typically over two to three months. Proceeding to full civil litigation would extend the timeline by a year or more and increase back-pay exposure substantially.
The decision to pursue settlement early was driven by a clear risk assessment. A rodo shinpan (labour tribunal) finding against the employer carries significant reputational and financial consequences. Social security contribution arrears can also arise where termination is later declared void, since the employment relationship is treated as uninterrupted. For international employers, that consequence is frequently overlooked. Our employment law practice in Japan addresses precisely these layered risks.
Key milestones and complications
The first milestone was the initial labour commission conciliation session, held approximately six weeks after the claim was filed. The employee's representative sought reinstatement and twelve months of back-pay. The client's opening position offered a severance package structured around the statutory notice period and an additional ex gratia sum.
The primary complication arose from the collective agreement. The employee's representative argued that the collective agreement in place with the employee representative body required advance notice of any redundancy programme affecting more than a defined threshold of the workforce. The client had not provided that notice. This procedural gap strengthened the employee's position significantly.
A second complication involved the employment contract itself. The contract had been drafted in English with a Japanese translation appended. The translation diverged from the original on the clause governing notice periods. Under Japanese employment legislation, ambiguities in employment contracts are generally resolved in the employee's favour. The longer notice period in the Japanese-language version therefore applied.
These two issues – the collective agreement gap and the contract translation discrepancy – shifted the settlement calculus. The client accepted that a higher severance figure was necessary to resolve the matter at the tribunal stage rather than risk a civil court ruling. The matter settled at the second labour tribunal hearing. The employee received a negotiated severance payment covering arrears and a forward-looking sum. No reinstatement was ordered. The social security position was regularised. For context on how Japanese corporate compliance intersects with employment obligations, the firm's corporate law practice in Japan provides related guidance on subsidiary governance structures.

Transferable lessons for cross-border employment matters
Lesson one: Dismissal procedure is non-negotiable. Japan's labour legislation treats dismissal validity as a substantive question, not a procedural formality. A termination that lacks documented justification under the four-factor test is vulnerable regardless of the business rationale behind it. International employers must build the documentation before issuing a dismissal notice, not after a claim is filed.
Lesson two: Collective agreements and employee representative bodies carry real legal weight. Many foreign employers treat the collective agreement as a low-priority formality. In Japan, it is a binding instrument. Failure to comply with consultation requirements in a collective agreement can invalidate a termination or significantly increase the compensation owed. Reviewing the collective agreement before any restructuring is a prerequisite, not an afterthought.
Lesson three: Bilingual employment contracts require rigorous consistency. Where an employment contract exists in two languages, inconsistencies between the versions create legal risk. Japanese courts apply an employee-protective interpretation. The lesson is straightforward: bilingual contracts must be reviewed by a lawyer in Japan with expertise in both languages before execution, and again before any termination decision is made. A similar pattern of risk arises in other high-growth markets, as documented in the firm's case study on employment disputes in the UAE.
