N5 Context

In many languages, asking a question requires changing the entire word order. In Japanese, it is much simpler! To ask a question, you simply keep the sentence exactly as it is and add the particle to the end. In this chapter, we will learn how to use this particle and master the essential words for seeking information.

1. The Question Particle: か (ka)

The particle か (ka) acts like a spoken question mark. When you add it to the end of a sentence, it signals that you are asking for information.

2. The Big Five Question Words

To ask for specific information, you drop a question word into the slot where the answer would normally go.

4. Cultural Note: The Concept of ‘Enryo’ (遠慮)

Enryo is a vital Japanese cultural concept meaning “reserve,” “restraint,” or “modesty.” It involves holding back one’s own desires or questions for the sake of others or to maintain social harmony (Wa).

  • When asked “Would you like some tea?”, a person might initially refuse due to enryo, even if they are thirsty.
  • When asking questions, Japanese people often use “softening” phrases like Sumimasen (Excuse me) to show they are aware they might be bothering the other person.
  • Understanding enryo helps you realize that “No” might sometimes mean “I’m being polite,” and “Yes” might sometimes be a bit hesitant!
