US GPA to Japan conversion
Last updated: August 4, 2026
Enter a US 4.0-scale GPA to see the approximate Japan equivalent. Handy for applications, transfers and credential evaluation.
Japan conversion reference table
Japan uses a S/A/B/C / GP 4.0. These mappings follow common credential-evaluation practice, but every institution sets its own policy — always confirm with the receiving school.
| US GPA | Japanese grade (秀/優/良/可) |
|---|---|
| 4.0 | 秀 / S (90–100) |
| 3.7 | 優 / A (85–89) |
| 3.3 | 優 / A (80–84) |
| 3.0 | 良 / B (75–79) |
| 2.7 | 良 / B (70–74) |
| 2.3 | 可 / C (66–69) |
| 2.0 | 可 / C (60–65) |
| 1.0 | 可 (just pass) |
| 0.0 | 不可 / F (<60) |
How to read it
Find your US GPA in the left column; the right column gives the closest Japan equivalent (S/A/B/C / GP 4.0). Conversions are approximate.
Japan grading culture
GPA is a comparatively recent addition to Japanese higher education: many universities only began calculating and publishing an official GPA figure from around the 2010s, following a national push from the education ministry (MEXT), and plenty still lead with the traditional 秀/優/良/可/不可 (S/A/B/C/fail) categories rather than a numeric average.
Common conversion pitfall
GPA calculation is not yet fully standardised across Japanese universities, so two schools can compute a "GPA" from the same run of S/A/B/C grades differently — for example, whether a bare pass (可) counts toward the average at all. Treat a Japanese GPA as an approximation and check it against the underlying letter-grade transcript where possible.
Frequently asked questions
Is this an official Japan conversion?
No. Universities and evaluators (e.g. WES, ECE) apply their own formulas — treat this as a guide.
How do I get my US GPA first?
Use the GPA calculator for one term or the cumulative GPA calculator across your degree.
Why are conversions only approximate?
Grading scales differ in shape and meaning between countries, so any mapping is an estimate.
