At the beginning, the characters have not yet been finalized. You can trace them on the printed matter first, then take off the characters on the paper and write very slowly on the white paper by yourself, imitating writing. There is no need to be fast at this stage. Just seek images and good looks, and then slowly increase your writing speed after your handwriting is basically formed. After all, writing for work and study in the future is not the same as writing calligraphy, and you still need to have some speed. However, it must be based on the fact that your calligraphy has been finalized. In fact, many people who write Japanese are also writing Chinese, so it doesn’t matter if they are sketchy. As long as it is not a crazy calligraphy, people can basically understand it. The purpose of practicing calligraphy is to change it before you have finalized it. , and persistence is the most important thing.
For most people, it is a bit difficult to change the font if it has been fixed. After all, it can be said that the strokes of writing are already a habitual pattern, so it will take more time and energy, but don’t go past it. Don't worry, you have just started learning Japanese, there is still room for improvement. I wish your handwriting will become more and more beautiful in the future. You don’t need to be too refined, just make it comfortable for people to read.
