Recently, I've become interested in Japanese anime again and as is the case with any interest, the internet is the perfect place to immerse oneself in that interest. I now know what otaku means, about the concept of mecha and many of the tropes associated with anime, manga and other aspects of Japanese culture.
One of the coolest and most enjoyable sites that I have subscribed is Culture Japan, created by Danny Choo. His personal story is a great example of lifelong learning that isn't a buzzphrase - I highly recommend reading his How Discovering Japan Changed My Life blog post even if you have no interest in the rest of his varied content.
If you have a passing interest, or a burning passion, connecting to the web (and consequently other people) is the best way to take control of your own learning.
