This is a late night variety program, and they had a short special on "bijin seiyuu" (pretty voice actresses), on 1998.03.09. The total time was around 10 minutes.
I was really lucky to catch this, and I just happened to come home at that time, and looked at the TV listing in the newspaper. I put a blank Hi8 in the VCR and turned on the TV.. (^_^;)
The first part was an introduction and interview with Iwao Junko. They showed some clips of her concert (December 1997), and showed some of her CDs and videos that she had released.
Then they interviewed two young seiyuu (actually not seiyuu yet), who were going to seiyuu school.
There was a CM, and then they went to Sakurai Tomo.
Then there was a couple minutes each on Nagashima Yuko and Kasahara Rumi. They showed clips of Yuko "working" (doing voices for narration).
