Japanese Transitive and Intransitive Verbs

Japanese transitivity concerns a verb’s valency: the participants it selects and the case particles those participants take. A prototypical intransitive clause presents one participant undergoing an event, while a transitive clause adds an agent acting on a target. In the usual dictionary terminology, 自動詞 (jidōshi) are intransitive and 他動詞 (tadōshi) are transitive. ¹

The core case pattern

The intransitive target is commonly marked with が. In the corresponding transitive clause, an agent is marked with が (or the topic particle は) and the target with を. English translations often hide the difference because the same verb can translate both members of the Japanese pair. ²

• バスがとまります。 basu ga tomarimasu. — The bus stops.
• （だれかが）バスをとめます。 (dareka ga) basu o tomemasu. — Someone stops the bus.

Thus とまる describes the bus stopping, while とめる describes someone causing it to stop. The particle choice follows the clause’s argument structure; it does not mean that が itself is an intransitive marker or that を is a transitive marker. The University of Texas reference table places 止める and 止まる in the same verb pair. ³

Paired verbs

Many Japanese verbs belong to morphologically related transitive–intransitive pairs. Examples include ふえる (increase) / ふやす (increase something), かたむく (tilt) / かたむける (tilt something), and きえる (disappear or go out) / けす (extinguish or turn off). Kadir reports Satou’s inventory of 1,256 such pairs, 22.6% of the verbs in that study, and uses Kageyama’s lexical conceptual structure to analyze the causative relationship: the transitive member represents an action causing a change that the intransitive member presents as occurring. ⁴

The endings are useful cues, not a derivation rule that licenses inventing new verbs. Learn each pair as two dictionary items with its own meanings and restrictions. Reference tables help with review, but they do not replace those entries. ⁵

Limits of the heuristic

が and を have wider grammar beyond this contrast. Topic は can replace either in a main clause, stative and potential constructions use different case patterns, and を can mark a departure point or a path rather than a direct object, as in 家を出る (leave home) and 橋を渡る (cross a bridge). Location phrases introduce another set of roles, covered in japanese-location-particles. ⁶

For study, a useful card contrasts complete minimal clauses rather than asking for an English gloss that collapses both members. That keeps the case frame attached to each lexeme and gives production cards a specific structural cue. Confusing the two members during live composition is also a concrete place to observe lexical competition.
