tooru-vs-wataru

When you walk across a bridge or pass through a hallway, which Japanese verb do you reach for — 通る (tooru) or 渡る (wataru)? For English speakers these two verbs can feel interchangeable because English often uses “cross” or “pass” for both. But Japanese draws a precise distinction: one verb focuses on moving through a space, and the other focuses on crossing from one side to another. Getting this right immediately makes your Japanese sound natural.

Yuka

Hey Rei! I keep mixing up 通る and 渡る. Can you break it down for me?

Rei

Sure! They’re both useful words but used in different situations. Let me walk you through it with some examples!

At a Glance: 通る vs. 渡る

通る (tooru) — Passing Through or Along

通る means to pass through, pass along, or go through a space. The key idea is movement along a route or through an area — not necessarily reaching the other side, but traveling via that route. It is also used figuratively when something “gets through” (a proposal passes, sound travels through a wall).

The particle を is used with 通る to mark the space being passed through.

Example 1 — passing through a street:

毎朝この道を通ります。
Maiasa kono michi wo toorimasu.
I pass through this road every morning.

Example 2 — passing through a gate:

改札を通るときにカードをかざしてください。
Kaisatsu wo tooru toki ni kaado wo kazashite kudasai.
Please hold your card over the reader when passing through the ticket gate.

Example 3 — figurative use (a proposal passes):

彼の提案が会議を通った。
Kare no teian ga kaigi wo tootta.
His proposal passed in the meeting.

Yuka

Oh, so 通る is used that way! I never thought about it like that.

Rei

Exactly! Once you see it in context a few times, it starts to feel natural. The key is paying attention to 通る when you read or listen.

渡る (wataru) — Crossing from One Side to Another

渡る means to cross over something — a bridge, a river, a street, an ocean, or even a border. The defining feature is that there are two sides and you are moving from one to the other. The journey itself matters less than the fact that you have crossed the boundary.

Example 1 — crossing a bridge:

橋を渡ると駅があります。
Hashi wo wataru to eki ga arimasu.
When you cross the bridge, there is a station.

Example 2 — crossing a street:

横断歩道を渡ってください。
Oudanhodou wo watatte kudasai.
Please cross at the crosswalk.

Example 3 — crossing an ocean (going abroad):

彼女はアメリカに渡って医師になった。
Kanojo wa Amerika ni watatte ishi ni natta.
She crossed over to America and became a doctor.

Yuka

And what about 渡る? I always thought it was the same as 通る…

Rei

Easy mistake! 渡る has its own distinct meaning. The difference becomes really clear once you compare them side by side — which is exactly what we’re doing here!

The Bridge Question: 通る or 渡る?

This is the classic confusion point. A bridge connects two sides, so 渡る (cross) is the natural choice. 通る can technically be used if you think of the bridge as a route you travel along — but native speakers almost always say 橋を渡る, not 橋を通る. Here is the reasoning:

The rule of thumb: if there is a clear other side you are aiming for, use 渡る. If you are traveling along a route or through an enclosed space, use 通る.
