thanks! I haven't seen Osen in any of the poh kims here.
TWO long rows of shelves in that shop here just for Japanese
movies and series alone.
I think there are at least 50 Japanese series on sale at any one
time!
Sadly, they had to stop importing the Korean series because the
Koreans are pushing for some kind of licensing fees. However,
since I'm such a regular, they have allowed me access to the
motherload. 
I'll keep a lookout for Osen or food-related shows.
