How to learn 日本語 again as someone who grew up in japan and is now rusty

Hello! i appreciate anyone who reads my story so I will do my best to keep it brief, Essentially I grew up in Tokyo from age 4 all the way until 13 and moved to america in 2013-2014. My japanese has gotten so rusty as I’ve not been practicing due to life changes; going to college, not having any japanese people to practice with in my area. Now i’m extremely rusty and want to gain my comfort and knowledge back with having casual conversations.

Some of my family still lives in japan and i plan to visit soon after being away for 10 years, Ive tried college classes here but haven’t found them to be very useful in my long term usage or memory. But i know when im immersed in it again it will come right back.

What resources and ways would you all suggest could help get me back to studying and being fluent again? I can only study two times a week for the time being. I’d love to hear people’s own stories of studying back to being proficient as well.

Thank you so much!
