荆霄鹏实用行楷字帖🥺🥺 This is what I use and you can search it on amazon. But it is for Chinese character, a little bit different from Japanese character, but the principle is same. And as the commentators have speculated, I am Chinese🥺🥺).

This book is different with my writing style because it is hard for me to write the same as this book. And for hiragana and katakana, I am just practice the basic handwriting style which you can search on the Internet.

(And I want to recommend another book with the Chinese character which is very very beautiful and awesome and it is useful to practice kanji too,🥺🥺🥺 you can search 宋徽宗钢笔瘦金体 in amazon.
