From the site:
"Since 1996, Japanese-Online.com has been providing free learning services to people who wish to study the Japanese language. We also now provide a means for Japanese learners to find and talk to one another, as well as seek language exchange relationships with Japanese speakers. Japanese speakers seeking language exchange partners are also invited so you will soon find people to study with!
Beginning September 2004, we have started a membership registration system to provide more advanced services to our members. Membership has always been, and is still now, completely free. Due to our popularity, we have been recently forced to begin a waiting list, but new members are still being accepted as space allows.
Please take a look about - several lessons are available to you without registration. Registered users get access to many more lessons, our popular forums, our profile search function, and all other features available here at Japanese-Online."
Nice site. Good content. Required login for access to all lessons.
This site has been around for a while and the lessons are good.
