Japanese workbook suggestions?

Hello Everyone!

My cousin is learning Japanese and for her birthday, her mom and I want to give her some good workbooks and any helpful learning material for her journey. (Her mom asked me but I’m learning Korean and have no idea for Japanese lol)

She’s a senior in high school and a beginner in Japanese.

Anyone have any recommendations of workbooks or anything that might be helpful?

Physical and online recommendations would be very helpful!

Thank you!!
