Used Japanese painting brush set, art supplies, brushes, brooms, sizing

Thank you for looking.
This is a set of used brushes and a duster that a family member purchased and used about 15 years ago.
They were used in an art class, but as I am not an expert, I cannot tell if they are specifically for Japanese painting. Please check the images.
If you have any questions, please feel free to ask in the comments.
I will answer to the best of my ability.
I can also upload one more image if needed, so please let me know if there's a specific part you'd like to see. (Maximum of 20 images can be posted.)
