Convert to note

Introduction to Japanese Language and Culture

This lesson focuses on a practical passage (kaiwa) to teach useful Japanese expressions, greetings, and grammar. It caters to both JLPT exam candidates who want to practice Japanese scripts (hiragana, katakana, kanji) and learners focused on conversational skills using romanized text.

Key Expressions and Greetings

  • Use of polite expressions like sumimasen (excuse me) when asking questions.
  • Common Japanese meal expressions: itadakimasu (said before eating) and gochisousama (said after eating) with cultural context.
  • Honorific prefix o- in words like otaku (someone else's house) to show respect.

Understanding 'Koto' in Japanese Grammar

  • Koto is a noun meaning "thing," "matter," or "incident," used to nominalize verbs and adjectives.
  • Usage with verbs: Verb (plain form) + koto turns the verb phrase into a noun phrase.
  • Usage with nouns: Noun + no koto means "about/regarding [noun]."
  • Usage with adjectives: Adjective + koto to express abstract concepts.
  • Examples:
    • 忘れたことがありますか? (Have you forgotten about it?)
    • 日本文化のことを知っていますか? (Do you know about Japanese culture?)

Joining Adjectives and Verbs

  • Joining i-adjectives with -kute (e.g., 赤くて - akakute).
  • Joining verbs with -kute to connect actions.

Using 'Amari' for Negation

  • Amari means "not very" or "not much" and is used with negative verbs and adjectives.
  • Example: あまり行きたくない (I don't really want to go).
  • Phonological variant anmari is used in conversation for emphasis.

Particles and Time Expressions

  • No mae ni (before [action]) to indicate an action before another.
  • No ato de (after [action]) to indicate an action following another.
  • Difference between -te kara and -ato de:
    • -te kara implies the second action happens immediately after the first and is often under the subject's control.
    • -ato de indicates the second action happens after the first but not necessarily immediately and may be out of the subject's control.

Practical Examples

  • 食べる前に手を洗ってください (Please wash your hands before eating).
  • 授業の後で映画を見ました (I watched a movie after class).
  • 毎日シャワーを浴びてから寝ます (I sleep after taking a shower every day).

Cultural Insights

  • Japanese often join hands and say itadakimasu before meals as a form of gratitude.
  • Use of honorifics and polite forms reflects respect in communication.

Summary and Practice Tips

  • Practice forming sentences using koto with verbs, nouns, and adjectives.
  • Use amari in negative sentences to express limited degree.
  • Differentiate between -te kara and -ato de for sequencing actions.
  • Engage in conversations using the expressions and grammar points learned.
