Here is a clip that we usually watch when we have visitors from outside Japan, if you have studied Japanese at least a little you will probably get a lot of enjoyment out of it:
A Group of Cats Learning Japanese (you will need flash installed to view this clip)
SHIMBASHI - The Yamanote Line
CHIBA - Japanese Prefectures (Thanks to Stephen Shores for the tip)
[Scot's note: these are both done by the comedy duo "The Ramens", who also did the video series I posted a little while ago]
If you have found a fun way to learn Japanese that works for you, please leave a comment.
