Rocket Japanese — PA
Probably the best language tool I've come across. Actually love it more than Rosetta Stone and Duolingo. I will definitely be paying for the full product.
The 6 day free preview is a blast to field languages to see if they will work for you. I strongly recommend everyone consider the ASL which is not what I typically expect to find in language courses. Full immersion with video only. Great for hearing and hard of hearing who are lip readers.
Tempted to overload with multiple languages (looked at Korean. After one look I have a far better understanding of written Korean)
Absolutely worth it!
