If you have ever tried to follow a Japanese conversation about school life, you may have noticed that people rarely say “seventh grade” the way textbooks do. Instead they say 中1 or 高3 — compact, casual shortforms that every native speaker uses but no phrasebook bothers to teach. This guide walks you through the entire Japanese school system, from kindergarten to university, with the vocabulary you actually need.
Yukaお子さんは今何年生ですか？ (What grade is your child in now?)
Rei小3です。あっという間に大きくなりました。 (She's in third grade. She grew up so fast.)
At a Glance: Japanese School Levels
| Level | Japanese | Reading | Years Covered |
|---|---|---|---|
| Kindergarten | 幼稚園 | youchien | Ages 3–6 |

幼稚園 (Kindergarten) — Ages 3 to 6
幼稚園 in Japan has three years: 年少 (age 3–4), 年中 (age 4–5), and 年長 (age 5–6). Most children in Japan begin school at age three, which surprises many English speakers. Note that some families use 保育園 (hoikuen, daycare/nursery school) instead, which accepts children from a younger age. The two systems are similar but formally distinct.
Yukaお姉ちゃんの子供が幼稚園児なの。 (My elder sister's child is a kindergartner.)
Reiたまに、姉ちゃんの子供を幼稚園へ送り迎えしてるよ。 (I sometimes drop off and pick up my sister's child from kindergarten.)
Yuka日本では3歳から幼稚園に通うよ。 (In Japan, children usually start kindergarten from age 3.)
小学校 (Elementary School) — Grades 1 to 6
Elementary school covers six years. The formal names are 小学1年 through 小学6年, but in casual speech everyone uses the short forms: 小1, 小2, 小3, 小4, 小5, and 小6. These short forms are completely normal among friends and family but should be avoided in business settings.
Rei兄貴の娘が来年の4月から小学校に入学するよ。 (My elder brother's daughter will start elementary school next April.)
Yukaお子さんは今小学生ですか？ (Is your child in elementary school now?)
Rei今小6だよ。 (I'm in 6th grade now.)
中学校 (Junior High School) — Grades 7 to 9
Junior high school is three years: 中学1年 (7th grade), 中学2年 (8th grade), and 中学3年 (9th grade). The casual shorthand is 中1, 中2, 中3. This is compulsory education in Japan, and it is where most school anime and manga are set, so you will encounter this vocabulary constantly in Japanese media.
Yukaこの春から中学生だよ。 (I'm starting junior high school this spring.)
Rei今中学2年だよ。 (I'm in 8th grade now.)
Yuka中学校ではバスケ部だったよ。 (I was in the basketball club in junior high.)
高校 (Senior High School) and 大学 (University)
Senior high school is three years: 高校1年 (10th grade), 高校2年 (11th grade), 高校3年 (12th grade), with the shortcuts 高1, 高2, 高3. University has four years: 大学1年 (freshman) through 大学4年 (senior), also abbreviated as 大1 through 大4. The third year of high school (高3) is notoriously stressful in Japan because of university entrance exams.
Rei高２だよ。 (I'm in 11th grade.)
Yuka高校生に戻りたいなー。 (I miss my high school days.)
Rei4月から大学生なんだー。 (I'm going to be a college student from April.)
Yuka大学時代に起業したかったよ！ (I wanted to start a business during my university days!)
