Japan vs Portugal Grading System
Enter your grade to convert between Percentage (0–100) — 60 to pass and 0–20 Scale (10 to pass)

You'll get the classification it corresponds to, the range it falls in rather than a single false-precise number, and how firm that answer is.
How does the Japan grading system work?
Japanese universities use a 100-point percentage scale where 60 is the minimum pass. The descriptors (可/良/優/秀) are standard national designations.

How does the Portugal grading system work?
Portuguese universities use a 0–20 scale inherited from the French tradition. Pass mark is 10. Grades of 18–20 are rarely awarded.

Do Japan and Portugal mark to the same standard?
No — and it is the difference in marking culture, not the arithmetic, that makes a direct comparison mislead. Here is how each country actually uses its own scale.
What a good grade means in Japan
Japanese marking is conservative at the top. The 秀/S band above 90 is genuinely uncommon, and 優 (80–89) is the highest grade most strong students earn routinely — so an average in the 80s is a good degree rather than a modest one, and an aggregate above 90 is exceptional. The other thing worth knowing is that undergraduate grades carry less weight in Japanese graduate admission than they do almost anywhere else: entry usually turns on an entrance examination and on a prospective supervisor agreeing to take you.
What a good grade means in Portugal
As with other 20-point systems, the top of the Portuguese scale is barely used: marks above 17 are uncommon and 20 is effectively unattainable, so a 15 or 16 represents a strong degree rather than the mediocre 75–80% it resembles when converted arithmetically. The honours labels at 18 and above are worth stating on an application precisely because the number alone does not communicate how rare they are.
Will a grade from Japan get you into Portugal?
We do not yet hold published entry requirements for Portugal, so we do not compare your grade against a bar we cannot cite. The conversion above still tells you how your result reads in Portugal terms.
90%+ (Excellent) → approximately 4.0 GPA. 80–89% → approximately 3.3 GPA.
What goes wrong converting grades from Japan to Portugal?
Japan rarely awards near the top of its own scale, so a result that looks modest in Japan terms converts higher than a direct comparison suggests.
Mistakes specific to Japan grades
- Assuming your GPA drives graduate admission in Japan. Entrance examinations and supervisor agreement matter more, which is why we publish no grade threshold for Japan.
- Treating 60 as a low pass. It is the Japanese pass mark, so the scale's usable range is narrower than in countries passing at 50.
- Reading an 80 as unremarkable because it is 80%. 優 is the highest grade most students regularly achieve.
What should you do next, applying from Japan to Portugal?
- Check the course, not the country. Entry requirements are set per programme and revised every cycle. We hold no published national bar for this destination, so the course page is the only figure that binds.
- Check whether an evaluation is even required. Unlike the US and Canada, Portugal universities commonly assess foreign transcripts in-house. Confirm on the course page before paying for a report you may not need.
- Get your documents moving early. Universities normally require your transcript sent directly by your institution rather than as a copy from you, which takes longer than most applicants expect.

What do these grading terms mean?
- Percentage scale
- A 0–100 marking scale — but the numbers are not comparable across countries: 70% is an outstanding result in the UK and a modest one in India.
- GPA (Grade Point Average)
- The US way of expressing an overall grade, on a 0–4.0 scale where 4.0 is the top — so a 4.0 is roughly what a 90–100% or a First Class would be elsewhere.
- Transcript
- The official document from your university listing every subject you took and the grade you got — not the same as your degree certificate, and universities abroad want both.
- Credential evaluation
- A paid report from an approved company that restates your foreign qualification in local terms, which many US and Canadian universities require before they will assess you.
- Grade compression
- Where a marking culture rarely uses the top of its own scale, so the highest grades anyone actually earns sit well below the theoretical maximum.
- Credits / credit hours
- A measure of how much a subject counts toward your degree — bigger subjects carry more credits and pull your average further.
Frequently asked questions
What is a 90 from Japan on Portugal's scale?
Approximately 17.1–20.0 / 20 — Muito Bom (Excellent). That is a range rather than a single number because grade conversion is an estimate, and the range widens where either country's data is less certain. Enter your own grade in the converter above for your figure.
