Info req. for 1993's HIGH SCHOOL TEACHER

[Matango]

Can anyone provide brief cast and credits for the Toho/TBS "psychodrama"
(for want for want for a better description), original Japanese title I
believe being KOKO KYOSHI, and the director being Shinji Nojima.

I'd appreciate knowing who sang the songs, and what else the two leads
and the director have done. Am I correct in assuming the film is set in
Kamakura?

Thanks.

Miles
