Knowledge and Understanding of Japanese Language and Culture
What you must understand
This domain tests explicit knowledge: script, grammar terminology, and cultural conventions embedded in language use.
Script. Know the three scripts and their roles: hiragana for inflections and native words, katakana for loanwords, onomatopoeia, and emphasis, kanji for content. Know basic kanji components and readings - on'yomi (Sino-Japanese) and kun'yomi (native). Long vowels, small っ (sokuon), and ん behave differently across scripts; katakana extends vowels with ー.
Grammar metalanguage. Be able to name and identify particles (は topic, が subject, を object, に direction/time, で location/means), transitive/intransitive pairs (開ける/開く), giving and receiving (あげる/もらう/くれる), and conditional forms (と、ば、たら、なら).
Culture. Understand honorifics, the distinction between 本音 and たてまえ, seasonal greetings, gift-giving conventions (お中元、お歳暮), bowing, and the role of 敬語 in workplace hierarchy. Know that 内/外 and 上/下 shape language choice.
Traps to watch
- Particle confusion: に marks existence location (教室にいる); で marks action location (教室で勉強する).
- Giving/receiving direction: あげる = I give out; くれる = someone gives to me; もらう = I receive.
- Conditional nuance: と is automatic consequence, たら is temporal/conditional, なら is topical.
- Culture questions rewarding stereotypes: choose the answer describing a convention, not a claim about personality.
Rule of thumb
For particles, ask what role the noun plays: location of existence (に), location of action (で), or direction (へ/に).
Worked example: 「公園{に/で}子供が遊んでいる。」 The action 遊ぶ happens at the park, so で is correct: 公園で子供が遊んでいる。But 「公園に子供がいる」 uses に because いる expresses existence. The verb type decides the particle.
