Meaning & Definition

Watasu is the everyday verb you reach for the moment something physical changes hands: a letter slid across a desk, a wrapped gift held out with both arms, coins counted back into your palm. It sounds small, but it is one of the most-used verbs in daily Japanese life.

Watasu (渡す) is a transitive godan verb meaning to hand over, pass, or give something directly to a person. It follows the pattern hito ni mono o watasu (person に thing を渡す) — hand the thing to the person. So tegami o watasu means to hand over a letter, purezento o watasu means to hand over a present, and otsuri o watasu means to hand back change. Watasu has an intransitive partner, wataru (渡る), which means to cross over rather than to hand over — compare hashi o wataru (to cross a bridge) with baton o watasu (to pass a baton). The two verbs share the same root idea of something moving across a distance, but watasu always needs someone actively doing the handing, while wataru describes something or someone simply crossing. Watasu also appears in compounds: tewatashi (手渡し) means handing something directly in person rather than mailing or leaving it, and hikiwatasu (引き渡す) means to hand over or deliver up something more formally, such as property, documents, or even a person in custody. As a godan verb, it conjugates as watashita (past), watasanai (negative), and watasareru (passive, to be handed something).

How to Use It

The trap almost every learner falls into is mixing up watasu (to hand over, transitive) with wataru (to cross, intransitive) — they look and sound like a matched pair because they are one, but only watasu takes a direct object marked with を and a person marked with に. Remember the structure hito ni mono o watasu: the person receiving comes first with に, the thing being handed over comes second with を. Another word learners often confuse with watasu is ageru (to give): ageru emphasizes the act of giving as a gift or favor and the social relationship behind it, while watasu is more neutral and physical — it simply describes the motion of something passing from one hand to another, gift or not. Finally, tewatashi (手渡し) is worth knowing separately: it specifically flags that something was handed over in person, as opposed to being mailed, dropped in a mailbox, or sent electronically.

Example Sentences

Cultural Context

Watasu and wataru form one of the clearest examples of Japanese transitive-intransitive verb pairs, a grammar pattern that trips up nearly every learner at some point. In these pairs, the transitive verb (watasu) requires someone to actively cause the action and takes an を object, while the intransitive verb (wataru) describes the thing or person simply undergoing the movement on its own, without naming who caused it. Once you notice the su/ru pattern here, you start spotting it across dozens of other pairs in Japanese, making watasu a useful anchor word for understanding the whole system.

How something is physically watasu-ed also carries etiquette in Japan. Business cards, gifts, and money are traditionally handed over with both hands (ryoute de watasu) rather than tossed or passed with one hand, as a sign of respect and care toward the item and the person receiving it. Handing something across with just one hand, especially in a formal setting, can come across as careless. This is part of why tewatashi (手渡し, in-person handover) is often specifically requested for important documents in Japan even in an age of email and courier delivery — the physical act of watasu-ing something still signals attentiveness and trust.
