Every grade Tohoku University awards, the points it carries, and whether it counts toward the GPA or earns credit. This is the table the calculator above runs on.
| Grade | Meaning | Mark range | Points | GPA counted | Credit earned |
|---|---|---|---|---|---|
| AA | AA | 90–100% | 4.0 | Yes | Yes |
| A | A | 80–89.999% | 3.0 | Yes | Yes |
| B | B | 70–79.999% | 2.0 | Yes | Yes |
| C | C | 60–69.999% | 1.0 | Yes | Yes |
| D | Fail | 0–59.999% | 0.0 | Yes | No |
Tohoku University converts every graded course into quality points by multiplying the grade's point value by the course's credit hours. Your semester GPA is the total quality points divided by the total credit hours that count toward the GPA, and the result is cut off (always rounded down) to 2 decimal places. Points run from 0.0 up to 4.0, so a higher average is a better result. The scale has no plus/minus steps, so every grade in a band is worth exactly the same number of points.
D works the other way: it earns no credit but is still counted in the average at 0.0 points, so a failed course pulls the average down while adding nothing to your progress.
Tohoku Semester and Cumulative GPA are credit-weighted averages of grade points; values beyond the second decimal point are truncated. In practice that means your existing CGPA is turned back into quality points by multiplying it by your completed credits, this semester's quality points are added on, and the total is divided by your new credit total. Both the semester and the cumulative figures are cut off (always rounded down) to 2 decimal places. Repeat handling is not published as a rule this calculator can apply automatically, so retaken courses need to be checked against the current catalog.
Tohoku University shares the 4.00 GPA scale with International Christian University, Keio University, Kyushu University and 2 others, while Kyoto University, Nagoya University, Osaka University and 1 other grade on a different scale. Rounding is not uniform either: Tohoku University has its cumulative average cut off (always rounded down) to 2 decimal places, whereas International Christian University, Keio University and 6 others do it differently. Repeated courses are handled differently again at Osaka University.
A GPA only means something alongside the scale it was calculated on, which is why comparing raw numbers between institutions — even neighbouring ones — is unreliable. See the Japan comparison table for every university covered there side by side.
Each example below is run through the same engine the calculator uses, so the numbers show Tohoku University's own rounding.
A student sitting at 2.88 after 60 completed credits takes 3 courses worth 3 credits each.
Semester GPA 2.00 · Updated CGPA 2.76
The semester total is 18 quality points over 9 counted credits. Because the cumulative average now spans 69 credits, one semester moves it only a little — this is why a CGPA gets harder to shift the further into a degree you are.
The same semester again, but the last course comes back as D (Fail) instead.
Semester GPA 2.00 · Updated CGPA 2.76
The semester GPA stays at 2.00, and the cumulative average stays at 2.76. D is worth 0.0 points and earns no credit, so it weighs the average down while adding nothing to your degree progress.
A student with a 2.88 CGPA after 60 credits takes 4 courses worth 3 credits each (12 credits in total). Here is where that CGPA lands if every course comes back at the same grade — calculated with the Tohoku University scale and rounding.
| If every course is | Semester GPA | New CGPA | Movement |
|---|---|---|---|
| AA (4.0) | 4.00 | 3.06 | +0.18 (better) |
| A (3.0) | 3.00 | 2.90 | +0.02 (better) |
| B (2.0) | 2.00 | 2.73 | −0.15 (worse) |
| C (1.0) | 1.00 | 2.56 | −0.32 (worse) |
| D (0.0) | 0.00 | 2.40 | −0.48 (worse) |

These are the places where the Tohoku University rules differ from what most students assume, and where a hand calculation usually goes wrong.
Assuming your GPA rounds up
Tohoku University cuts the cumulative average off at 2 decimal places rather than rounding to the nearest. A calculated 3.4989 is recorded as 3.49, not 3.50 — which matters when a scholarship or honours threshold sits on the boundary.
Dropping a failed course from the calculation
D earns no credit toward the degree, but it is still counted in the GPA at 0.0 points. Leaving a failure out flatters the result.
Borrowing plus/minus values from another university
The Tohoku University table has no plus or minus steps — every grade in a band is worth the same points. Intermediate values like 3.3 or 3.7 do not exist on this scale.
Averaging the grades instead of weighting them
A course worth twice the credits moves your GPA twice as much. Adding up your grade points and dividing by the number of courses ignores that weighting and is almost always wrong.
Expecting a 0-credit course to move the number
Tohoku University allows them, but with no credit hours they contribute nothing to either side of the division.
Handling a retake by guesswork
Repeat handling is not published as a rule this calculator can apply automatically, so retaken courses need to be checked against the current catalog. Check the current catalog before assuming an old grade has left your record.
C (1.0 points) is the weakest grade in the Tohoku University table that still earns credit. Anything below it — D — is counted in your GPA but earns no credit toward the degree. Individual programmes can set a higher minimum for courses in your major, so check your programme handbook as well.
4.0 on the 4.00 GPA scale, which you reach by earning AA (4.0 points) in every course that counts toward the GPA.
The cumulative average is cut off (always rounded down) to 2 decimal places, and the semester average is cut off (always rounded down) to 2 decimal places. Because the cumulative figure is truncated rather than rounded, a result just short of a threshold stays short of it — 3.4999 is recorded as 3.49.
No. This page is generated from the grading configuration for Tohoku University alone — its 5 point values, its floor rounding, and its own rules for pass/fail and repeated courses. Other universities in Japan routinely use different point values or a different scale entirely, so the same grades can produce a different GPA elsewhere.
Repeat handling is not published as a rule this calculator can apply automatically, so retaken courses need to be checked against the current catalog.
Your CGPA is weighted by every credit you have already completed, so a single semester moves it less the further along you are. Fifteen credits added to sixty already completed is a fifth of your record; the same fifteen added to a hundred and twenty is an eighth of it. Use the calculator at the top of this page with your real completed-credit total rather than estimating the movement.
AA covers 90–100% and is worth 4.0 grade points. The full percentage-to-grade table for all 5 graded bands is published on this page.
