The list has got quite a lot of my musical memories in my final year of the JET Programme, and not surprisingly, I've got 7 of the albums listed. Yumi Matsutoya was at her commercial peak during the late 80s and early 90s. With "Tengoku no Door", this was her 3rd consecutive album to top the annual album charts. Duos were also having a good year in the form of B'z and Chage & Aska. Certainly, Chage & Aska's mega hit of "Say Yes" was a major contributing factor.
Of course, Kazamasa Oda's BEST album of his solo hits since 1985, "Oh! Yeah!", also included the No. 1 single of 1991, "Love Story wa Totsuzen ni", but there are some other great songs in there, too, such as the title track and "Little Tokyo". I wish I could highlight the album but it's rather difficult to find the original songs on YouTube or anywhere else.
And Anri and Misato Watanabe were having some heady days themselves during the time with their own great albums.
