Education in Japan
MEXT2025 FINAL
9 years compulsory · 5.812m primary students · 3.105m lower secondary students
Japan's school system is built around nine years of compulsory education, beginning with six years of elementary school and continuing through three years of lower secondary school. Upper secondary education is not compulsory, but it is the standard next stage for most students. The latest final School Basic Survey shows 5.812 million elementary pupils, 3.105 million lower secondary students and 2.874 million upper secondary students in 2025. At the tertiary level, Japan combines high attainment among young adults with a large university sector and several recognized routes into higher education.

Japan Education System
| Stage | Typical duration | Typical age | Compulsory? | What it means |
|---|---|---|---|---|
| Elementary school | 6 years | 6 to 12 | Yes | Primary general education and the first six years of compulsory schooling. |
| Lower secondary school | 3 years | 12 to 15 | Yes | Completes Japan's nine-year compulsory education period. |
| Upper secondary school | 3 years full-time | Usually 15 to 18 | No | Full-time courses normally last three years. Part-time and correspondence routes also exist. |
| University | Usually 4 years | Post-secondary | No | One of several tertiary routes, alongside junior colleges, colleges of technology and professional training institutions. |
System structure follows MEXT's official education overview. Age ranges are the usual progression pattern and can vary for individual students.
Compulsory Schooling in Japan
Children who have reached age 6 are required to attend elementary school for six years. After elementary school, students continue to lower secondary school for three years, through the school year in which they reach age 15. Together, these stages form the nine years of compulsory education.
Japan also has compulsory education schools that combine grades 1 through 9 within a single institution. This changes the institutional format, but not the underlying nine-year compulsory span.
Student Numbers by Education Stage
| Education stage | Students | Change from previous year | Reference |
|---|---|---|---|
| Elementary school | 5.812 million | Down 129,000 | 2025 final |
| Lower secondary school | 3.105 million | Down 36,000 | 2025 final |
| Upper secondary school | 2.874 million | Down 33,000 | 2025 final |
| University, all students | 2,972,412 | Up about 23,000 | 2025 final |
| University undergraduates | 2,645,837 | Up about 18,000 | 2025 final |
| Graduate students | 277,132 | Up about 5,000 | 2025 final |
| Junior college students | 71,196 | Down about 7,100 | 2025 final |
| Professional training college students | 569,107 | Up about 11,000 | 2025 final |
MEXT's School Basic Survey uses institution-specific definitions. The university total includes undergraduate and graduate students plus other categories covered by the survey, so it should not be read as an undergraduate count.
Upper Secondary Education and Progression
Students who complete nine years of compulsory education may continue to upper secondary school. MEXT states that full-time upper secondary courses normally last three years, while part-time and correspondence courses last three years or more.
The standard route into university is graduation from an upper secondary school or secondary education school. MEXT also recognizes other entrance qualifications. These include certain equivalent domestic or overseas qualifications and the Upper Secondary School Equivalency Examination. Passing that examination can establish academic equivalency for university, junior college and professional training college entrance, subject to the applicable age rules.

Definition matters
This is not a generic national literacy rate
The OECD measure identifies adults at or below Level 1 on its proficiency scale. It should not be converted into a claim that Japan has an 89% or 99% basic literacy rate. Different surveys use different age groups, questions and proficiency thresholds.
What the Numbers Show
- Japan's school-age population continues to shrink. MEXT's final 2025 survey recorded new lows in elementary and lower secondary student numbers.
- The university sector remains large, with nearly 3 million students under MEXT's university-wide survey definition.
- Among 25 to 34 year-olds, tertiary attainment reached 66% in 2024, placing Japan well above the OECD average of 48%.
- Japan also performs strongly in the OECD adult literacy-skills comparison: 11% of adults age 25 to 64 were at or below Level 1, versus 27% across the OECD.
- These measures describe different things. Enrollment counts, educational attainment and adult skill proficiency should not be combined into one generic education score.
Scope and Data Boundary
This Education page covers the school system, current student counts, qualifications and progression, tertiary attainment and adult skills. Mean years of schooling and expected years of schooling are intentionally excluded because they belong to DigifyWorld's Human Development and Quality of Life vertical.
For current national counts, final MEXT School Basic Survey data is preferred. OECD data is used where an internationally comparable attainment or skills measure adds context. Figures retain their own reference year rather than being forced into a single artificial year.
Frequently Asked Questions
