Comparison
Read two legal systems against each other
Because every portal follows the same fifteen-section outline, the comparison is genuinely like-for-like rather than a collage of whatever each government happens to publish.

| Legal family | Civil law | Civil law with common-law influence |
| System of government | Federal presidential republic | Unitary parliamentary constitutional monarchy |
| Constitution | Political Constitution of the United Mexican States | Constitution of Japan |

| Capital | Mexico City | Tokyo |
| Official languages | Spanish, Nahuatl, Yucatec Maya | Japanese |
| Currency | Mexican peso (MXN) | Japanese Yen (JPY) |
| Population | 130,000,000 | 123,500,000 |
| Division of powers | Federal. Powers not expressly granted to the union are reserved to the 32 states (Article 124). States run their own civil, family and criminal-enforcement codes, but criminal procedure, labour and commercial law were federalised to produce single national codes. | Parliamentary government with the Cabinet collectively responsible to the Diet, and a Supreme Court holding the final power of constitutional review. |
| How law is made | Bills may be introduced by the President, either chamber, state legislatures or by citizens with 0.13% of the electoral roll. Both chambers must pass an identical text; the President may veto, and Congress overrides with two-thirds of each chamber. Constitutional amendments need two-thirds of Congress plus a majority of state legislatures (Article 135). | Most bills are Cabinet-sponsored, drafted by ministries and reviewed by the Cabinet Legislation Bureau, then passed by both houses; the lower house can override the upper by a two-thirds majority. |
| Legal profession | A law degree plus a cédula profesional from the Education Ministry licenses practice; there is no compulsory bar examination or single mandatory bar, which distinguishes Mexico from most of the region. Notaries public are a separate, strictly limited state-appointed profession with exclusive competence over real estate and company deeds. | Candidates pass the national bar examination, then complete a year at the Legal Training and Research Institute before qualifying as bengoshi, judge or prosecutor. |
A comparison table flattens nuance by design. Where a difference matters to a decision you are making, open both portals and read the section in full — the constitutional detail behind a one-line summary is often the part that governs the outcome.
