The Jukugo Structure Quiz is a free 4-choice web app for practicing how Japanese kanji compounds are built.
The original questions focus on general language patterns: similar meanings, opposite meanings, modifiers, verb-object relationships, subject-predicate relationships, negative prefixes, and affixes.
The app is designed for learners from around Grade 4 to junior high school. It starts with easy patterns and moves toward mixed questions that require comparing kanji relationships.
Each question has dynamic hints and simple self-made diagrams that split a compound into parts and show the relationship between the kanji.
The problems, choices, explanations, and diagrams are created independently for this app. They are not copied from textbooks, workbooks, exam papers, worksheets, or teaching materials.
My Page stores challenge history, best records, and often missed questions so learners can review weak patterns repeatedly.
Start by splitting each compound into two parts. Then ask, “Are the meanings close?”, “Are they opposite?”, “Does the first kanji describe the second?”, or “Can I read it as an action and its object?”
The hints are designed to guide that thinking step by step, so learners can review the reason behind the answer instead of only memorizing the label.
Because each quiz is short and automatically scored, it works well for warm-up practice, home study, classroom review, or checking weak patterns before a test.
