Legal Framework for Dismissal under the Labour Contract Act — Japan

Japan’s Labour Contract Act (労働契約法, LCA) provides the central statutory framework governing dismissal. The key provision is Article 16, which codifies the Japanese courts’ long-standing doctrine against abusive dismissal. In addition, Articles 17 and 19 impose special protections for fixed-term employees.

1. Article 16 — General rule against abusive dismissal

Article 16 provides that a dismissal is invalid where it:

1. lacks objectively reasonable grounds, and
2. is not considered appropriate under generally accepted social norms.

Thus, an employer does not have unrestricted discretion to terminate an employee merely because a contractual or workplace rule identifies a possible dismissal ground. The reason, the seriousness of the conduct, the employee's circumstances and the proportionality of dismissal are relevant.

The provision essentially transformed the judicially developed abuse-of-dismissal-rights doctrine into statutory law.

2. What constitutes an objectively reasonable ground?

Japanese employment law does not provide one exhaustive statutory list of grounds for ordinary dismissal. In practice, the courts have dealt with grounds such as:

• serious misconduct or disciplinary violations;
• persistent failure to perform duties;
• incapacity or inadequate performance;
• business/economic necessity;
• organisational restructuring;
• certain consequences arising from union-shop arrangements.

The employer must be able to demonstrate a factual basis for the dismissal and show that dismissal was appropriate in the circumstances.

3. Social appropriateness and proportionality

Even where a legitimate reason exists, the dismissal may still be invalid if dismissal is excessively harsh in the circumstances.

Courts may consider factors such as:

• seriousness of the employee's conduct;
• actual harm caused to the employer;
• whether the conduct was intentional;
• previous disciplinary record;
• length of service;
• circumstances surrounding the incident;
• whether lesser disciplinary measures were possible;
• treatment of comparable employees.

The Ministry of Health, Labour and Welfare specifically notes that even a workplace mistake does not automatically justify dismissal; the circumstances and degree of fault must be examined.

4. Disciplinary dismissal

A dismissal imposed as a disciplinary sanction is additionally subject to Article 15 of the Labour Contract Act.

Article 15 provides that disciplinary action is invalid where it lacks objectively reasonable grounds or is not socially appropriate considering the nature and circumstances of the employee's conduct.

Therefore, disciplinary dismissal generally requires examination of:

Misconduct → applicable work rule → factual proof → seriousness → proportionality → appropriate procedure.

The employer's Rules of Employment (Shugyo Kisoku) are particularly important because dismissal and disciplinary grounds are generally required to be addressed in workplace rules under the Labour Standards Act.

5. Fixed-term employees — Article 17

Article 17 gives fixed-term employees stronger protection during the contractual period.

An employer cannot dismiss a fixed-term employee before expiry of the agreed term unless there are unavoidable circumstances.

This threshold is stricter than the ordinary Article 16 test. In practical terms, an employer must have circumstances sufficiently serious to justify ending the employment before the agreed contractual end date.

Therefore:

Indefinite contract → Article 16 standard

Fixed-term contract during its term → Article 17's stricter “unavoidable circumstances” standard

6. Non-renewal of fixed-term contracts — Article 19

Expiry of a fixed-term contract and dismissal during its term are legally distinct.

Normally, a fixed-term contract ends when its contractual period expires. However, Article 19 protects employees where:

1. fixed-term contracts have been repeatedly renewed so that non-renewal is substantially equivalent to dismissal; or
2. the employee has reasonable grounds to expect renewal.

Where Article 19 applies, an employer's refusal to renew must have objectively reasonable grounds and be socially appropriate.

7. Notice requirements

The Labour Standards Act also operates alongside the Labour Contract Act. Generally, an employer dismissing an employee must provide 30 days' advance notice or payment in lieu of notice, subject to statutory exceptions.

Importantly, satisfying the notice requirement does not by itself make a dismissal substantively valid. The employer must still satisfy the relevant dismissal standard under the Labour Contract Act.

8. Special statutory restrictions

Dismissal may also be restricted by other legislation. For example, dismissal cannot lawfully be used to circumvent statutory protections concerning matters such as:

• discrimination;
• occupational injury and leave;
• maternity and childcare protections;
• trade-union activities;
• legally protected leave;
• other prohibited grounds under employment legislation.

Consequently, an employer should examine both Article 16/17/19 and the specific statutory circumstances surrounding the termination.

9. Major Japanese Case Laws

1. Japan Salt Manufacturing Co. Ltd. v. Employee — Supreme Court, 25 April 1975

日本食塩製造事件

This is one of the foundational Japanese dismissal cases.

The Supreme Court established the principle that even where a stated dismissal ground exists, an employer cannot automatically dismiss an employee. Dismissal becomes invalid where it lacks objectively reasonable justification and social appropriateness.

The case became a principal judicial foundation for the doctrine subsequently codified in Article 16.

Importance: It is the leading authority for the modern Article 16 dismissal standard.

2. Kochi Broadcasting Co. Case — Supreme Court, 31 January 1977

高知放送事件

An announcer had caused broadcasting accidents after oversleeping and subsequently submitted an inaccurate report concerning one incident.

Although the conduct fell within the employer's stated grounds for ordinary dismissal, the Supreme Court accepted the conclusion that dismissal was excessively harsh in the particular circumstances and therefore constituted an abuse of the dismissal right.

Importance: Demonstrates that the existence of misconduct does not automatically make dismissal valid; proportionality and surrounding circumstances matter.

3. Toshiba Yanagi-cho Factory Case — Supreme Court, 22 July 1974

東芝柳町工場事件

Workers had been employed under two-month fixed-term contracts that were repeatedly renewed—between five and 23 times.

The Supreme Court recognised that, where repeated renewals and the circumstances of employment make the relationship substantially similar to an indefinite employment relationship, the principles governing dismissal may apply to non-renewal.

Importance: This case became a foundation for the rule now reflected in Article 19(1).

4. Hitachi Medico Case — Supreme Court, 4 December 1986

日立メディコ事件

The employee had a series of two-month contracts renewed five times. The Court recognised that there was an expectation of continued employment sufficient for dismissal principles to be considered in relation to non-renewal.

However, the Court also recognised that temporary employees hired through relatively simple procedures under short-term contracts may legitimately have a different degree of employment protection from permanent employees.

Importance: It became the foundation for Article 19(2) concerning reasonable expectations of renewal.

5. Mitsubishi Plastics / Mitsubishi Jushi Case — Supreme Court, 12 December 1973

三菱樹脂事件

The case concerned termination during a probationary/trial arrangement.

Japanese case law recognises that an employer may have a broader scope for exercising a reserved cancellation right during a genuine probationary period. However, the exercise of that right must still have objectively reasonable grounds and be socially appropriate in light of the purpose of the probationary arrangement.

Importance: Establishes the special treatment of probationary employees, while retaining judicial control over arbitrary termination.

6. Japan Salt Manufacturing / Union-Shop dismissal principle

The Japan Salt Manufacturing decision also addressed dismissal pursuant to a union-shop agreement. The Supreme Court held that dismissal based on such an arrangement requires the underlying circumstances to justify the employer's obligation to dismiss; where the union's expulsion decision itself is invalid, the dismissal may lack the necessary objective justification.

Importance: Demonstrates that even contractual or collective-agreement mechanisms cannot automatically override the statutory/common-law restrictions on dismissal.

7. Panasonic Plasma Display Case — Supreme Court, 18 December 2009

パナソニックプラズマディスプレイ事件

This case is relevant to fixed-term employment and the legal consequences surrounding the use of fixed-term arrangements. It is among the cases identified by the Ministry of Health, Labour and Welfare in connection with Japanese fixed-term employment jurisprudence.

Importance: Shows the continuing judicial scrutiny of fixed-term employment arrangements and their substantive reality.

10. Practical legal test for a dismissal

A Japanese court examining dismissal can broadly be understood as asking:

11. Legal consequences of an invalid dismissal

Where dismissal violates Article 16, it is treated as invalid, rather than merely irregular. The employment relationship therefore continues legally. The employee may seek judicial remedies concerning the existence of the employment relationship and associated wage claims. The Ministry of Health, Labour and Welfare expressly describes an Article 16 dismissal as invalid where the statutory requirements are not met.

Conclusion

The Japanese Labour Contract Act creates a substantive control on employer dismissal power. Article 16 requires both objective reasonableness and social appropriateness. Article 15 adds protection against disproportionate disciplinary action, while Article 17 imposes a stricter standard for dismissal during a fixed-term contract and Article 19 regulates certain refusals to renew fixed-term contracts. The Supreme Court's decisions in Japan Salt Manufacturing, Kochi Broadcasting, Toshiba Yanagi-cho Factory, Hitachi Medico, Mitsubishi Jushi, and related cases form the principal judicial background to this statutory framework.
