There are too many general things mentioned on the Internet. Let me tell you the actual facts.
First of all, you have to listen more. There are many spoken Japanese words that are not found in written language, and many Japanese people speak wrong Japanese, which is actually very everyday Japanese.
For example, most people who have just gone to Japan will often hear Japanese people say suffixes such as けど and かしら. However, if you don't fully understand how to use them, you will often make a fool of yourself if you try to speak them like the Japanese.
There are also buzzwords: for example, sentences such as "Bendang bendang bendang" were very popular for a while, but in actual Japanese spoken language, if you use it like this, Japanese people will think you are KY. So sometimes you have to learn to judge. There are some dead words that Japanese people don't use, especially when foreigners use them, they are often shocked.
When LZ speaks Japanese, have you ever felt that even if you read along, there is always something wrong? I want to tell Liz, if you encounter such a situation, it is often because you are not used to this Japanese sentence, or you take it for granted that it is written language. It is very important to listen and read along at this time. Listen carefully and hear the difference until your pronunciation is natural. Even if you are listening to a very simple sentence, it will be a big improvement for you. It's like what Armstrong said when he landed on the moon, "That's one small step for me, one giant leap for mankind." If you understand the usage of a sentence, it actually doesn't mean much to your spoken language. , the most important thing is to be familiar with their accent. For example, Europeans and Americans will say "ready?" to you.
Then the method:
You must establish a Japanese system around you. Only then can you truly learn Japanese. For example, if something is confirmed in your brain, you will automatically blurt out OK. People who often speak Japanese are often immersed in the Japanese environment. This does not mean being abroad, but it means that you must have a complete environment for you to immerse yourself in. When I speak English to British people, I sometimes say hi unconsciously. This means that your brain has been affected by the Japanese environment. Once you develop this reaction, it will be easier for you.
