You have to 1 learn Japanese slowly, the most basic level 4 takes two months, and the first level takes at least one year. 2. Just buy standard Japanese as a teaching material. It is divided into primary and intermediate levels. After finishing primary school, it is the most basic level 4, so we must learn it well. After you have a solid basic skill, self-study is not a problem in the future. Might as well suggest a class. 3. Two books at the primary level are the third level and two books at the intermediate level are the second level. 4. After learning Level 1, buy some exercises to do, such as vocabulary, grammar, reading and listening. The pentatonic chart is the foundation. 5. Recite more words. Thinking about that behind your back will deepen your impression.
