Nainaitei 内々定

An informal job offer made before the formal offer date. Also written informal offer, unofficial offer, provisional offer.

The government's schedule for graduate hiring asks employers to start selection on 1 June of the students' final year and to make formal offers, naitei, from 1 October. The months in between are covered by the nainaitei: an informal promise that the company intends to make a formal offer. In practice offers come earlier still. In a survey by the Recruit group's research unit, 81.6% of university students graduating in 2026 already held an offer on 1 June 2025, the official start of selection.

The legal status differs from a naitei. An accepted formal naitei creates an employment contract, so withdrawing it is treated almost like a dismissal. A nainaitei usually does not go that far, because pay, conditions and joining procedures have not yet been set. It still has some legal weight. In the Kose RE case in February 2011, the Fukuoka High Court found no employment contract had formed. But it held that a company that withdrew a nainaitei a few days before the formal offer date, citing worsening business, had breached good faith and violated the student's protected expectation, and awarded damages.

Students commonly collect several nainaitei and decline all but one, so employers expect some to fall through. The term is also used, more loosely, for a verbal offer to a mid-career candidate before the paperwork.
