The Super Sunday: Yukiko Okada Special
The Super Sunday was a series of one-shot documentaries that aired on TV Asahi and affiliate stations from 1995 to 1997. This episode, which appears to have aired in Feburary 1997, focuses on Yukiko, her life, and her career.
There won't be much new information here to those already familiar with Yukiko's life, but this mini-documentary is still a great watch. The interviews with Aizawa and Fukuda truly make this worth watching, as well as a look into the Yukiko Okada fanclub that was active in the 1990s.
That's not to say this documentary is perfect (There is a somewhat sloppy moment where the date of her Heart Jack concert in Nagoya is given as 1985 instead of 1986), but overall this is a very well put-together programme that puts its 20 minute runtime to good use.
