I didn't see anywhere else where I could talk about live action Japanese drama, so I'm posting this one here, since it's supposedly based on a manga of the same name. I was lucky enough to find a DVD of this, and am enjoying it greatly. It's about foreigners in Japan learning the language, culture, social situations, and pitfalls along with their reluctant sensei.
I highly reccomend it if you can find it online. It reminded me of the japanesePod101's own iLove J-Drama, which I enjoyed too.
