🇵🇹 Portugal vs 🇯🇵 Japan
Tax residency, treaties and PE risk compared.
| Dimension | 🇵🇹 Portugal | 🇯🇵 Japan |
|---|---|---|
| Residency rule | 183 days OR habitual residence on 31 Dec | Jusho (domicile) + 1-year presence |
| Day threshold | 183 days | 365 days |
| Warning band | from 150d | from 183d |

| Best for | IFICI / NHR 2.0 applicants in scientific and tech roles | Non-permanent residents (first 5 of 10 years) shielding foreign income |

Verdict
Portugal and Japan carry similar residency risk on day-count alone — the deciding factor is usually treaty coverage (80 vs 85) and your specific income mix.
