The 給与改定通知書 (compensation revision notice) is the document the employer issues whenever
compensation changes beyond a clean pay raise. It records the prior structure, the new structure, the
delta at each line and on an annualized basis, the effective date, the reason, and the basis of the
change. When the change is unfavorable, it carries the employee acknowledgement block that records
consent under Article 9 of the Labor Contract Act (LCA).
1. Article 9 LCA: consent for unfavorable changes
Article 9 LCA prohibits the employer from making working-condition changes that are unfavorable to
the employee without the employee's agreement. The signed acknowledgement block in the notice is the
standard form of that consent. "Acknowledged receipt" is not consent: the wording must explicitly
state agreement. The template uses "I agree to and consent to" wording for this reason.
2. Article 10 LCA: reasonableness test for work-rules amendments
Where the employer relies on amended work rules to push through an unfavorable change without
individual consent, Article 10 LCA imposes a reasonableness test: business necessity, the
proportionality of the change, comparison with industry norms and compensatory measures, and the
procedural fairness of the labor / management dialogue. The reasonableness explanation field in the
template is for that record.
3. Live before / after, delta, and annual impact
The before and after structures sum live in the preview. The monthly delta, the percentage change,
and the annual impact (delta multiplied by 12) update as you type. Use this to sanity-check the size
of the change and the picture the employee will see when they read the notice.
4. Fixed-overtime allowance (固定残業代) treated as a separate line
Fixed-overtime structure is regulated separately: the breakdown between regular pay and fixed
overtime, the equivalent overtime hours, and the treatment of overtime above the fixed amount must
all be transparent. The template surfaces the allowance amount and the equivalent hours as their own
fields so the structure stays visible across the revision.
5. Standard monthly remuneration (標準報酬月額) note
A compensation change that shifts the standard monthly remuneration grade by 2 or more after 3
consecutive months triggers an occasional revision filing (月額変更届) under Japan Pension Service
rules. The template's optional item flags this for the employee and reminds payroll to verify.
6. Edit anything that doesn't match your case
Click Edit on the toolbar above the preview and the notice becomes editable in
place. Use this for case-specific wording (e.g., post-merger banding letters, performance-improvement
findings). When you turn editing off, your changes stay; the form fields keep driving the
highlighted variables.
