Salary is often in 万円
Many forms label 年収（万円） — annual income in 万円 (man-en). You type 500 meaning ¥5,000,000/year, not five hundred yen.
Employment type dropdowns
- 正社員 (seishain) — permanent / full-time employee
- 契約社員 (keiyaku-shain) — fixed-term contract employee
- 派遣社員 (haken-shain) — dispatched / temp-agency worker
- パート / アルバイト — part-time (パート often longer-term; アルバイト often student/casual — forms vary)
- 業務委託 / フリーランス — contractor (not always an “employee”)
- 自営業 (jieigyo) — self-employed
- 公務員 (komuin) — public servant
- 無職 / 学生 — not employed / student
年収 vs 月収
年収 (nenshū) = annual income. 月収 (gesshū) = monthly. Don’t put a monthly figure in an annual 万円 box.
Before tax is usual
額面 / 税込 (gross / before tax) is what most 年収 fields want unless they say 手取り (tedori) — take-home.
Visa / status is separate
A work-style dropdown is not the same as residence status (在留資格). Pick the employment type that matches how you’re paid or contracted; immigration status is usually a different field.
Other form norms
- Phone examples on JP sites often show
090-1234-5678, but many fields want digits only / half-width — see the Phone / 〒 tab. - 扶養 (fuyō) on tax/HR forms means dependents you claim — count people on the form’s rules, not “household vibes”.
- Company name often wants 株式会社 written out or as （株） per the form’s example — when unsure, copy from your contract or pay slip.

Crest generator
Simple original geometric motifs — not copies of any real family crest or registered mark.
Advice: hanko & kamon
- A hanko on a meishi is decorative. A printed or generated image is not a registered seal (実印) or bank seal (銀行印) — never use it for seal registration, banking or contracts.
- Foreign residents can register a seal at the city office (印鑑登録). You need a real carved seal; katakana or romaji is often accepted, but rules differ by municipality — check yours.
- Common choices: 認め印 (mitome-in) for everyday receipts and paperwork, 実印 (jitsu-in) for the registered seal, 銀行印 for your bank account. Many procedures now accept a signature instead.
- Kamon (家紋) are crests passed down in families. On a card, use only your own family’s crest or an original design — not another family’s crest, a company logo or a registered mark.
- General information only, not legal advice or a guarantee — confirm with the city office or bank.
Lines
Standard Japanese order: company → department → title → name (kana) → 〒, address, phone, URL.
