What is the Japanese Grading System?
The Japanese grading system is a standardized academic evaluation method used across elementary schools, secondary schools, and universities in Japan to assess student performance. Unlike many Western countries that primarily use letter grades (A-F), the Japanese system employs a unique combination of letter grades, kanji characters, and percentage ranges to denote academic achievement levels.
The grading system is overseen by the Ministry of Education, Culture, Sports, Science and Technology (MEXT), which sets national educational standards. In Japanese universities, the most common grading scale uses five main categories: S/秀 (Exemplary), A/優 (Very Good), B/良 (Good), C/可 (Pass), and F/不可 (Fail). Each grade corresponds to specific percentage ranges, with 60% typically being the minimum passing threshold.
Japanese academic grading emphasizes not only test scores but also factors such as classroom participation, homework completion, and behavioral conduct. At the elementary and secondary levels, report cards often include evaluations of students' social behavior, teamwork, and respect for school rules, reflecting Japan's holistic approach to education that values character development alongside academic achievement.
Japanese Grade Scale Table
The following table shows the standard Japanese grading system used in most universities and high schools, including the kanji characters, letter grades, percentage ranges, English descriptions, and GPA equivalents:
| Kanji | Letter Grade | Percentage Range | English Description | GPA (4.0 Scale) | Status |
|---|---|---|---|---|---|
| 秀 (shū) | S | 90-100% | Exemplary, Excellent | 4.0 | Pass |
| 優 (yū) | A | 80-89% | Very Good | 3.0-3.9 | Pass |
| 良 (ryō) | B | 70-79% | Good | 2.0-2.9 | Pass |
| 可 (ka) | C | 60-69% | Average, Satisfactory | 1.0-1.9 | Pass |
| 不可 (fuka) | F | 0-59% | Fail, Unacceptable | 0.0 | Fail |
Important Note: Some institutions may use additional grades like 認 (nin) for "Approved/Acceptable" (50-59%) or D as a conditional pass, though these are less common. The S grade (秀/shū) is often reserved for exceptional performance and may not be awarded in all courses.
Formulas and Conversion Methods
Percentage to Letter Grade Conversion
The conversion from percentage scores to Japanese letter grades follows a straightforward conditional formula based on score ranges:
Grade Conversion Formula:
If \( P \geq 90 \) → Grade = S (秀)
If \( 80 \leq P < 90 \) → Grade = A (優)
If \( 70 \leq P < 80 \) → Grade = B (良)
If \( 60 \leq P < 70 \) → Grade = C (可)
If \( P < 60 \) → Grade = F (不可)
Where \( P \) = Percentage Score (0-100)
GPA Calculation Formula
To calculate your GPA on the 4.0 scale from Japanese grades, use the following conversion:
GPA Conversion Formula:
\( \text{GPA} = \frac{\sum (\text{Grade Point} \times \text{Credits})}{\sum \text{Credits}} \)
Grade Points:
S (90-100%) = 4.0
A (80-89%) = 3.0
B (70-79%) = 2.0
C (60-69%) = 1.0
F (0-59%) = 0.0
Pass/Fail Determination
Pass Status Formula:
If \( P \geq 60 \) → Status = PASS
If \( P < 60 \) → Status = FAIL
These formulas are standardized across most Japanese educational institutions, ensuring consistency in academic evaluation. The minimum passing percentage of 60% represents the threshold for demonstrating acceptable mastery of course content.
How This Calculator Works
Calculation Methodology
This Japanese Grade Calculator employs a rule-based conditional algorithm that processes percentage inputs and applies the official Japanese grading standards to generate accurate results. The calculator follows these systematic steps:
- Input Validation: The system first validates that the entered percentage is within the valid range of 0-100. Any input outside this range triggers an error message prompting the user to enter a valid score.
- Range Identification: Once validated, the calculator identifies which grade bracket the percentage falls into using conditional statements that compare the input against the five standard thresholds (90, 80, 70, 60, and below 60).
- Grade Assignment: Based on the identified range, the calculator assigns the corresponding letter grade (S, A, B, C, or F) along with its kanji character representation (秀, 優, 良, 可, or 不可).
- GPA Calculation: The system converts the letter grade to its equivalent GPA value on the 4.0 scale using the standardized conversion table (S=4.0, A=3.0, B=2.0, C=1.0, F=0.0).
- Status Determination: The calculator determines pass/fail status by checking if the percentage meets the minimum passing threshold of 60%.
- Results Display: All calculated values—letter grade, kanji, percentage, description, GPA, and pass status—are displayed in a formatted results panel for easy reading.
The calculator uses client-side JavaScript processing, ensuring instant results without requiring server communication. All calculations are performed using the official MEXT-recognized grading standards, guaranteeing accuracy and reliability for academic planning purposes.

Frequently Asked Questions
What percentage is considered passing in Japan?
In the Japanese education system, 60% is the minimum passing score. Any score of 60% or above receives a passing grade (C/可 or better), while scores below 60% result in a failing grade (F/不可). This 60% threshold applies to most universities and high schools, though some specialized programs may have higher requirements.
Is the S grade (秀/shū) commonly given?
The S grade, representing "Exemplary" or "Excellent" performance (90-100%), is relatively rare in Japanese universities. Many professors reserve this grade for truly outstanding work that significantly exceeds expectations. Some institutions only award S grades to the top 5-10% of students in a course, making it a prestigious achievement that distinguishes exceptional academic performance.
How does the Japanese GPA system work?
Japanese universities typically use a 4.0 GPA scale where S=4.0, A=3.0, B=2.0, C=1.0, and F=0.0. To calculate your cumulative GPA, multiply each grade's point value by its credit hours, sum all these products, then divide by your total credit hours. For example: \( \text{GPA} = \frac{(4.0 \times 3) + (3.0 \times 4) + (2.0 \times 3)}{3 + 4 + 3} = \frac{30}{10} = 3.0 \)
Can I convert Japanese grades to US grades?
Yes, Japanese grades can be converted to US equivalents, though the conversion isn't always direct. Generally: S → A (4.0), A → B (3.0), B → C (2.0), C → D (1.0), and F → F (0.0). However, many US institutions perform their own evaluations using services like World Education Services (WES) to ensure accurate and fair conversion that accounts for differences in grading rigor.
Do all Japanese schools use the same grading system?
While the S/A/B/C/F system with corresponding kanji is widely standardized across most universities, there can be variations. Some institutions use additional grades like 認 (nin) for conditional passing, or implement plus/minus modifiers (A+, A, A-). Elementary and secondary schools often use a simpler 5-point scale (5=Excellent, 4=Good, 3=Average, 2=Below Average, 1=Fail). Always check your specific institution's grading policy for precise details.
What happens if I fail a course in Japan?
If you receive an F grade (不可/fuka) with a score below 60%, you fail the course and do not receive credit. Most Japanese universities allow students to retake failed courses in subsequent semesters. However, both the original F grade and the retake grade typically appear on your transcript. Failing multiple courses can affect your academic standing, scholarship eligibility, and visa status for international students.
How important are grades for employment in Japan?
In Japan's employment culture, grades are moderately important but not the sole determining factor. Japanese companies (especially large corporations) often request transcripts and may ask for your GPA during recruitment. However, they place equal or greater emphasis on factors like university prestige, club activities, internship experience, interview performance, and cultural fit. Maintaining at least a B average (良/ryō) is generally recommended to remain competitive in the job market.
Can I use this calculator for MEXT scholarship applications?
Yes, this calculator can help you estimate your academic standing for MEXT (Japanese Government) scholarship applications. However, MEXT evaluations consider your entire academic record, not just individual test scores. For undergraduate scholarships, maintaining an average of A (優) or higher is typically competitive. For graduate scholarships, strong grades combined with research experience and recommendations are crucial. Always refer to the official MEXT guidelines for specific eligibility requirements.
