〜はず

Let's tackle 〜はず (hazu). This is a really useful phrase in Japanese, and you'll hear it all the time. Essentially, 〜はず expresses that something is expected or that something should be the case, based on some information or reasoning. It's like saying, "I'm pretty sure this is how it is," or "Logically, this is what should happen." It implies a reasonable expectation, not just a guess.

Think of it as a way to show a moderate level of certainty. You're not 100% guaranteeing something, but you have good reasons to believe it. It's stronger than just saying you *think* something, but not as absolute as stating a fact without any room for doubt.

§ Basic Meaning: "Supposed to be" or "It should be"

Definition

Supposed to be; it should be (expresses expectation or certainty).

When you use 〜はず, you're indicating that you have a reason for your belief. This reason could be something you heard, something you observed, or a logical deduction. For example, if you know a store closes at 9 PM, and it's 8 PM, you'd say it *should be* open.

• Hint: The store should still be open.

Here, the speaker expects the store to be open based on its usual operating hours. There's a logical reason behind the expectation.

• Hint: He should have arrived already.

In this case, the speaker might know the person left early or that the journey doesn't take long. Based on that information, they expect the person to have arrived.

§ When to use it: Expressing your reasonable expectation

You use 〜はず when you have a good reason to believe something is true, even if you haven't directly confirmed it. It's often used when:

• You have reliable information: Someone told you something, or you read it.
• You've made a logical deduction: Based on what you know, it makes sense that something is true.
• You're expressing a strong likelihood: It's very probable.

Let's look at a few more examples to solidify this understanding.

• Hint: This bus should go to the station.

Perhaps you checked the bus route or someone told you, so you have a good reason to believe it.

• Hint: The test was easy, so I should be able to pass.

Here, the speaker's reasoning is that the test's difficulty suggests a positive outcome. It's a logical expectation.

It's important to remember that while 〜はず expresses strong expectation, it's not absolute certainty. There's always a slight possibility that your expectation might be wrong. If something unexpected happens, you might use it with a sense of surprise or disappointment, like "It *should have* happened, but it didn't!" We'll get into that nuance a bit more later, but for now, focus on its core meaning of reasonable expectation or logical likelihood.
