1, the first recommendation is a website in https://hinoki-project.org/natsume/, where common words can be found.

"Japanese Composition Support" システムなつめ

This website mainly provides some fixed collocations of Japanese words. In our daily writing, it often happens that we write a noun but don't know what verbs it is usually used with or what conjunctions are. This website can solve our troubles. It is no exaggeration to say that this website is simply a lifeline for the author to write a project report in college! Next, I'll tell you how to use this website.

For example, if we want to search for the usage of the word "interest", we can enter it in the keyword field and click search, and the commonly used collocation verbs and auxiliary words of "interest" will appear, such as "interest", "interest" and "interest".

It should be noted that the dark pink in the picture represents the use frequency of this collocation, which means that the greater the proportion of dark pink, the more common this collocation is in daily use. Click on each collocation, and we can also see examples from Yahoo, various books and newspapers. The advantage of these examples is that you can learn the most authentic Japanese collocation in practical use ~

Secondly, I recommend (https://so-zou.jp/web-app/text/proofreading/) that the usage of this website is also very simple. Just put the written Japanese article into this blue search box and click Check, and it will quickly check your expression, Chinese characters and auxiliary words.

Personally, I think the accuracy is still very high. For example, if you enter an erroneous paragraph of Japanese, it will quickly find out the user's mistakes in words and Chinese characters, and will also give suggestions for revision. In addition, this website also has some functions that I think are very humanized-you can enter up to 10,000 words, and even very long papers can be copied and pasted without repeating chapters, which is simply the gospel of the authors!
