일본어 공부, 진작 이렇게 할걸… 10년 차 통역사가 직접 보여주는 일본어 독학법

Main Ideas

The video presents a beginner-friendly, sentence-based approach to studying Japanese called the “piece” or “sculpture” study method. Instead of focusing first on mastering grammar or memorizing complete sentences, learners start with short sentences they want to say, break them into parts, and reuse those parts to create new sentences.

The instructor says she initially struggled to learn Japanese before developing this method. She describes herself as a Japanese interpreter with ten years of experience and a Japanese broadcast reporter.

The Study Method

1. Write five short sentences about your day. Keep them simple and practical. Examples from the video include taking a walk in the park, feeling cold because it rained, buying an apple, having lunch with a grandchild, and watching a drama. The instructor recommends building a foundation with simple sentences before attempting more complicated ones.

2. Break each sentence into basic “pieces.” The instructor groups sentence elements into four categories:

   • Name pieces: Nouns, such as park, apple, or grandchild.
   • Action pieces: Verbs, such as went, bought, or watched.
   • Feeling pieces: Adjectives or states, such as cold.
   • Decorative pieces: Adverbs or other details, such as this morning, at night, or how much.

Japanese particles are treated as connecting pieces that show how words relate to one another.

1. Use a translation tool for support. Copy each Korean sentence into an AI tool and request a Japanese translation. Ask for the sentence without kanji, with Korean pronunciation, and with slashes marking the same phrase divisions as in the Korean. The tool can also help check whether a sentence sounds natural or combine two sentences. The video presents AI as a study aid, not a replacement for understanding the sentence.

2. Copy the Japanese sentences by hand. Write the Japanese above or below the original Korean sentence. Beginners who cannot yet read Japanese characters can use the Korean pronunciation as a guide. The instructor recommends copying the characters carefully, even if it initially feels like drawing their shapes. She says repeated writing helped her learn kana more naturally than relying only on a chart.

3. Mark and label the pieces. Add slashes where the sentence naturally divides. Underline each part and label it as a name, action, feeling, decorative, or connecting piece. Note the meanings of unfamiliar particles and expressions as they appear.

4. Build a reusable list of pieces. Collect words and expressions from the sentences in lists by category, including their Korean meanings. The instructor notes that even a few sentences can produce a useful collection of vocabulary and sentence elements.

5. Reuse the pieces to make new sentences. Swap one piece for another—for example, change “at night” to “this morning.” You can also gradually add pieces to expand a short sentence, such as changing “I watched a drama” to “I watched a drama with my grandchild at night.”

Combine pieces from earlier sentences to express new ideas. If a sentence becomes too complex, start with two simple sentences and connect them later as you learn the relevant forms.

1. Check, repeat, and speak aloud. Ask the AI tool to review sentences you have assembled, especially when you are unsure whether they sound natural. Practice saying the sentences aloud, and, if possible, get feedback from a Japanese speaker. The instructor also mentions that her classes offer one-on-one conversations with native Japanese teachers.

Key Lesson

The method is based on creating, analyzing, and recombining sentences, rather than memorizing complete sentences in isolation. The suggested routine is to write five sentences about each day, break them into parts, build a personal list, and use those parts to create and say new sentences. The instructor argues that consistent practice can make Japanese study more practical and help learners express their own thoughts.
