I am just developing an online language tool to help to learn Japanese (among other Asian languages). I have currently 40 lessons online, it is free to use and runs in your browser.
Learn Japanese language for free with 40 online Japanese lessons
I am now actively looking for people to give me feedback so that I can decide which features I will implement next. So I would really appreciate to hear from you. Also, if there is anything not working properly, please let me know. Thank You!
