How the Japanese School System Works: Grade Structure Explained

Moving to Japan with children? One of the first things you need to understand is how the Japanese school system is structured. Japan's education system is highly organized, internationally respected, and follows a clear grade structure that differs from many Western countries. This guide breaks down everything foreign parents need to know — from preschool through university — so you can make informed decisions about your children's education in Japan.

Overview: Japan's 6-3-3-4 School System

Japan follows what is known as the 6-3-3-4 system, named for the number of years spent at each level:

• Elementary School (小学校, Shōgakkō): 6 years
• Junior High School (中学校, Chūgakkō): 3 years
• Senior High School (高校, Kōkō): 3 years
• University/College (大学, Daigaku): 4 years (2-3 years for junior college)

Compulsory education covers the first 9 years: all of elementary school and junior high school. While high school is not legally mandatory, an impressive 98.8% of junior high graduates go on to enroll in high school, making it effectively a universal step in Japanese education.

For foreign families, this structure is both reassuring and important to navigate correctly. The Japan National Tourism Organization (JNTO) also provides an official summary of the Japanese educational system for reference. Public elementary and junior high schools accept foreign children free of charge, putting them on equal footing with Japanese students in terms of access to education. To learn more about the overall education landscape, see our Complete Guide to the Japanese Education System for Foreign Families.

Grade-by-Grade Breakdown: Ages and Levels

Understanding which grade your child belongs to in Japan can be tricky due to Japan's April-to-March school year. Here is a complete grade-by-grade reference:

Note: Japan's grade placement is based on birth year. Children born between April 2nd of one year and April 1st of the following year are placed in the same grade. This means your child's grade level may shift by one year compared to their home country.

For a detailed look at what happens at the elementary level, see our guide to Elementary School in Japan for Foreign Parents. For an official overview of grade and age structures, PLAZA HOMES has a helpful reference chart that foreign families living in Tokyo will find particularly useful.

Before School: Early Childhood Education in Japan

Before formal schooling begins, Japanese children typically attend either:

• Hoikuen (保育園) – Daycare centers for children aged 0–5, operated under the Ministry of Health, Labour and Welfare
• Yōchien (幼稚園) – Kindergartens for children aged 3–5, operated under the Ministry of Education

Since October 2019, the Japanese government provides free early childhood education for children aged 3 to 5 at approved facilities, covering public kindergartens, certified daycare centers, and combined facilities (認定こども園). Families with children aged 0 to 2 may qualify for subsidies based on household income.

Foreign families are generally eligible for these programs as long as the child is a resident of Japan. Enrollment can be competitive in urban areas, especially for hoikuen spots for infants. See our full guide to Daycare and Hoikuen in Japan for enrollment tips.

Elementary School (小学校): Grades 1–6

Elementary school is the starting point of Japan's compulsory education and runs from age 6 to 12. Children typically enter first grade the April after they turn 6.

What students study:

• Japanese language (国語)
• Mathematics (算数)
• Science (理科)
• Social studies (社会)
• Music (音楽)
• Art and crafts (図工)
• Physical education (体育)
• Homemaking/life skills (家庭科, starts in Grade 5)
• English (英語, compulsory from Grade 3; formal English instruction became mandatory from 2020)

English was added as a compulsory subject in elementary school from April 2011 (as an activity) and became a formal graded subject from Grade 5 onward starting in 2020. This is great news for foreign families, as it shows Japan's growing openness to international communication.

Foreign children attending public elementary schools are not required to take entrance exams. However, they must live within the school's catchment area (学区). The school will typically be assigned by your local municipal office (市区町村役場) based on your registered address.

Junior High School (中学校): Grades 7–9

Junior high school (ages 12–15) is the second and final stage of compulsory education in Japan. After elementary school graduation in March, students automatically advance to the junior high school within their district.

Curriculum at junior high includes:

• Japanese, Mathematics, Science, Social Studies
• Foreign language (almost universally English)
• Music, Art, Technology & Home Economics
• Physical Education
• Moral Education (特別の教科 道徳)

The academic workload increases significantly in junior high. Students also participate in school clubs (部活, bukatsu) — either sports or cultural clubs — which are a central part of Japanese school culture and social life.

Approximately 70,000 foreign students in Japan currently require dedicated Japanese language instruction. Public schools are obligated to provide support, including special Japanese classes, bilingual staff, and in some areas, mother-tongue support.

If your child struggles with the language or academic content, parents can request placement in a lower grade — a common accommodation for newly arrived foreign students. For more on what to expect, see our Guide to Junior High School in Japan for Foreign Families.

Senior High School (高校): Grades 10–12

High school in Japan is not legally mandatory, but it is culturally expected. The remarkable 98.8% enrollment rate among junior high graduates reflects how central high school is to Japanese social and professional life.

Types of high schools:

• General academic high schools (普通科) — the most common type, focused on university preparation
• Vocational high schools (専門学科) — focused on agriculture, industry, commerce, nursing, and other trades
• Comprehensive high schools (総合学科) — a mix of academic and vocational courses

Unlike the automatic progression from elementary to junior high, high school requires an entrance examination. Students take exams (either public or private school exams) in their third year of junior high (around age 15).

For foreign families, this is a critical transition point. If your child has been attending Japanese school, they will need to prepare for these exams. Alternatively, international schools offer a different path. See our Guide to High School in Japan for Foreign Families for a full breakdown of options, including international baccalaureate programs.

Private high school enrollment stands at 31.1%, reflecting the strong demand for private education at this level.

The School Year Calendar: April Starts and Long Vacations

One of the biggest adjustments for foreign families is Japan's school year schedule. Japan's school year starts in April and ends in March, which is the opposite of many Western countries.

Key dates in the Japanese school calendar:

• April: New school year begins; entrance ceremonies (入学式)
• Late July – Late August: Summer vacation (夏休み) — typically 6 weeks
• Late December – Early January: Winter vacation (冬休み) — approximately 2 weeks
• Late February – Late March: Spring vacation (春休み) — approximately 2 weeks, between school years
• March: Graduation ceremonies (卒業式)

This April start means that if you arrive in Japan mid-year, your child may be joining school partway through a Japanese school year. Schools are generally accommodating to mid-year enrollees, particularly at the compulsory education level.

Public vs. International Schools: Making the Right Choice

Foreign families in Japan typically weigh two main options:

Public schools offer full Japanese immersion and free education — a genuine advantage for families planning a long-term stay in Japan. International schools provide continuity with home-country curricula and are popular with families on short-term assignments.

For families considering international options, see our Definitive Guide to International Schools in Japan.

Additionally, Living in Nihon provides a comprehensive overview of the broader picture of raising children and education in Japan for foreigners, which is particularly useful for newly arrived families trying to understand all their options at once.

Language Support and Bilingual Education

One of the most common concerns for foreign parents is how their child will cope in an all-Japanese environment. Here is what to know:

• Public schools are legally required to provide Japanese language support to foreign students
• Many municipalities offer dedicated Japanese as a Second Language (JSL) classes
• Some schools have bilingual staff or translators for common languages
• Around 70,000 foreign children in Japan currently receive such support nationally

Beyond school support, many foreign families invest in supplementary language programs. Our guide to Teaching Japanese to Foreign Children covers effective strategies, from immersion methods to structured tutoring.

If maintaining your child's home language matters to you, read Heritage Language Maintenance for Children in Japan for practical approaches to raising truly bilingual children.
