EJU Science study guide
EJU Science · Work through your exam, one topic at a time.
The Examination for Japanese University Admission for International Students (EJU) is administered by JASSO, the Japan Student Services Organization, and is used by Japanese universities and other schools when they admit international students. Science is one of the subjects listed alongside Japanese as a Foreign Language, Japan and the World, and Mathematics. Inside Science, JASSO publishes three separate syllabuses - Physics, Chemistry and Biology - each defining the scope of what may be examined. Revised Science, Japan and the World, and Mathematics syllabuses apply to the questions of the 2026 EJU 1st Session, so study material built on the older Science content is out of date and should be replaced before you begin. Topics on this exam: Physics, Chemistry, and Biology. The EJU Science study guide has 3 sections and about 795 words.
01Physics: Model Selection and Quantitative Setup
Physics on the EJU tests mechanics, thermodynamics, waves, electricity and magnetism, and atomic physics. Most items ask you to choose a model, set up equations, and interpret a graph or numerical result. Mechanics: resolve forces on a free-body diagram; use ΣF=ma componentwise. Energy and momentum conservation are often faster than kinematics when time is unknown.
290 words, about 1 min02Chemistry: Moles, Equilibrium, and Functional Groups
EJU Chemistry tests atomic structure and bonding, the mole and solutions, chemical equilibrium, acids and bases, redox and electrochemistry, and organic and inorganic chemistry. Quantitative items usually reduce to a mole relationship or an equilibrium expression. Amount of substance: n=m/M; for a gas at 0°C and 1 atm, n=V/22.4; concentration c=n/V. Bonding: ionic, covalent, and metallic bonds; electronegativity differences predict bond polarity; intermolecular forces affect boiling point.

EJU Biology covers cell structure and function, metabolism, genetics and reproduction, homeostasis, immunity, ecology, and evolution. Questions often combine a pathway diagram with a ratio or a feedback prediction. Cells: prokaryotes lack a nucleus and membrane-bound organelles; transport may be passive or active. Metabolism: photosynthesis has light reactions and the Calvin cycle; respiration runs glycolysis, the Krebs cycle, and oxidative phosphorylation.
