What this document is
A letter explaining WHY you cannot submit the income and tax-payment certificates, with a promise to file them once issued. Without it the application simply looks incomplete; with it Immigration sees an anticipated case.
What it must show
- Standard Japanese administrative-letter layout: date (right) → bureau name + 殿 → writer's name/nationality/date of birth/address (right) → the title 理由書 → opening → 記 with numbered points → 以上.
- What the app writes for you: your arrival and registration dates · the 1 January assessment rule that means no tax was levied · the substitute documents (three payslips + certificate of employment) · a promise to file the certificate once issued.
- Print it and SIGN by hand next to your name. Letters to Immigration should be in Japanese — the app handles that.
- Check before printing: take the arrival date from the entry stamp in your passport, and the registration date from the BACK of your residence card (住居地記載日).

Notes
If a law office files for you they usually write this letter themselves — hand them the app's version so you don't have to explain everything again.
