In most Western markets, hiring is reversible. You make an offer; the person accepts or declines; if it does not work out, you part ways. Each step is light. Japan flips every one of those assumptions.
A job offer in Japan — naitei — is not an offer in the casual sense. Under settled labour-law doctrine, the moment a candidate accepts, an employment contract has formed. Rescinding it without cause is functionally treated as wrongful dismissal. Founders who issue offers and then change their minds because a stronger candidate appeared have ended up in court more often than they expected to.
Dismissal of an existing employee is harder still. Article 16 of the Labor Contract Act requires "objectively reasonable grounds" and "social acceptability" before a termination is upheld. Underperformance, on its own, almost never clears that bar. This is why performance-improvement plans exist in Japan: not really to fix performance, but to build a contemporaneous paper trail that an employment tribunal will accept as evidence of process. Founders used to faster firing cycles consistently underestimate this — until the first time they need to act on it.
The foreign-worker picture in 2026 is bigger than people realise. [VERIFY: 2.3 million foreign workers in Japan, a record], spread across the Engineer/Specialist in Humanities/International Services visa, the Highly Skilled Professional categories, and the Specified Skilled Worker programme that expanded sharply over the last few years. Each carries different sponsorship obligations, and hiring even one foreign employee changes how Immigration looks at your own visa file at renewal.
Compensation expectations are their own world. Base salaries are paired with semi-annual bonuses that can run two to six months' pay. Employer-side social insurance adds roughly [VERIFY: 15%] on top of base. The 2025 shunto wage round closed at [VERIFY: 5.46%] — the largest spring settlement since 1990–91 — and that pressure is still working through the market. Equity, the default early-hire currency in Silicon Valley, motivates very few Japanese candidates the way founders expect it to.
What follows is the practical version: the naitei and dismissal rules every founder should know before extending the first offer, the visa categories that govern hiring foreigners, and how to put together a compensation package that actually competes.
