The 入社案内書 is the cover document of the joining package: the practical first-day instructions
that sit on top of every other document a new hire receives before they start. It is not the
employment contract; it is the orientation guide that makes day one navigable.
1. Send the package one to two months before
For new graduates: late January or February for an April 1 start. For mid-career hires: four to six
weeks before the negotiated start date. Bundle this document with the cover letter (送付状), the
document checklist (入社前提出書類リスト), and the health-check notice (健康診断受診案内).
2. Be specific about reporting time and location
State the exact reporting time, the building, the floor, and which reception desk. If your building
has multiple entrances, name the one to use. Always provide a one-line access note from the nearest
train station so candidates can plan their commute.
3. Name the person they should ask for
A generic "HR Department" instruction is harder to act on than "ask for Tanaka from HR Recruiting"
at the reception desk. Naming an individual reduces day-one anxiety and ensures the reception staff
can route them efficiently.
4. Lay out the schedule by time block
A 6- to 8-line schedule with start times and item names is enough. Standard items: reception,
orientation, contract review, office tour, lunch, department welcome, end of day. Keep the first
day light; substantive training usually starts on day two or week two.
5. Specify dress code and items to bring
Business attire is the safe default for day one. Standard items: the joining instructions, a
personal seal, photo ID, a pen, and a notebook. Items already collected via the checklist (pledge,
consent, health check) should not be repeated here.
6. Toggle the optional clauses
Lunch provision, transportation reimbursement, dress-code transition note, and accessibility note
are independent toggles. The defaults reflect common practice for office-based roles; adjust them
for retail, manufacturing, or remote-first companies.
