LAW OFFICE OF HAJIME IWAKI
Practice area

Management-side employment counsel.

Japanese employment law is unusually protective of employees, and the gap between what a foreign HQ expects and what Japanese law actually permits is where most of our clients' risk lives. We advise exclusively on the employer's side — terminations, restructurings, investigations, and the regulatory visits that follow them.

Scope of practice

What we handle.

01

Terminations & mutual separations

Structuring a defensible separation under Japanese law, which rarely permits unilateral termination on performance grounds alone. We design the process, draft the settlement or mutual termination agreement, and negotiate directly with the employee or their counsel where needed.

02

Restructuring & redundancy programs

Japan's four-factor test for economic dismissals sets a high bar. We design redundancy programs — selection criteria, severance calculation, consultation process — built to withstand scrutiny, and coordinate the message back to headquarters.

03

Labor Standards Inspection response

An unannounced or scheduled visit from the Labor Standards Inspection Office requires a coordinated, document-ready response. We attend, respond to findings, and close out corrective recommendations.

04

Harassment & workplace investigations

Independent, documented investigations into harassment or misconduct complaints, structured to meet the employer's statutory prevention-measure obligations and to hold up if the matter later escalates.

05

Fixed-term & contract-conversion analysis

Advice on fixed-term, part-time, and dispatched (haken) staff, including the Article 18 conversion rule for employees approaching five years of continuous fixed-term employment — a frequent blind spot for foreign HR teams.

06

Work rules & policy design

Drafting and updating work rules (shūgyō kisoku) and HR policies so they are enforceable under Japanese law while preserving as much of your global HR framework as the law permits.

Representative work

The pattern of what we handle.

Client identities are withheld. These describe the shape of engagements we handle routinely, not any single matter.

SaaS / technology

Multi-year management-side employment defense for a multinational SaaS provider, including Labor Standards Inspection follow-up and Article 18 conversion analysis across a growing fixed-term workforce.

Media / advertising

Japan restructuring and severance design for a foreign-owned advertising and communications agency, coordinated closely with APAC headquarters and local HR.

Industrial / hardware

Redundancy program design and consultation-process management for a foreign industrial equipment manufacturer scaling down a Japan business unit.

Logistics / SaaS

Ongoing outside-GC retainer for a European logistics and software group, absorbing settlement negotiation and termination work as it arose within the standing engagement.

Consumer / lifestyle

Harassment investigation and remediation plan for a foreign consumer brand's Japan sales team, run independently of the reporting line under complaint.

Entertainment

Termination and settlement strategy for a foreign game publisher's Japan studio during a headquarters-directed portfolio review.

How we work

What headquarters can expect.

Foreign HQ legal and HR teams are usually the actual audience for our work, even when the matter plays out entirely in Japan. We write and speak in plain English, flag risk levels headquarters will recognize, and are direct about what Japanese law does and does not allow — including when the answer is less flexible than headquarters hoped.

Practical questions

FAQ.

Can we terminate an underperforming employee the way we would at home?

Almost never without a structured process. Japanese courts apply a strict standard to unilateral dismissal, and a termination that would be routine in an at-will jurisdiction can expose the company to a wrongful dismissal claim and reinstatement risk in Japan. In most cases we recommend a negotiated separation, and we can tell you early whether your specific facts support it.

We received notice of a Labor Standards Inspection visit — what now?

Contact us before the visit if you have notice, or immediately after if it was unannounced. We can attend, help assemble the requested documentation, and manage the response to any corrective recommendation that follows.

Do you represent employees or unions?

No. Our employment practice is exclusively management-side. This is a deliberate choice, not a limitation of scope — it means there is no conflict of loyalty in how we advise you.

How fast can you respond to an urgent situation?

For retainer clients and Employment Crisis Response subscribers, partner triage begins within 24 hours of contact, with same-day review available for active inspection visits or imminent termination decisions. See Employment Crisis Response for details.
