Are there any scribbles in Japanese characters similar to China's running script and cursive script? What's it called?

Basically, there is no. In daily life, when writing Japanese characters, it is basically not allowed to write some cursive characters such as running script. Dear, I think it will be neat and beautiful to write in printed form ... besides, when they are writing calligraphy, they still have this way of writing. The reason why they are not allowed to write like this in peacetime is a national problem and a regulation. ..
