I first heard about Kei Marimura（真梨邑ケイ）since she had a splendid song on one of the "Good Times Diva" series CDs that I'd been collecting for a few years in Japan. Unfortunately, I have yet to find that song but she's still got plenty of tunes represented on YouTube.
Marimura is a jazz singer, TV/movie actress, novelist and porn actress. Yep, you read that last one correctly. I figured that I might as well get that particular occupation out of the way.
From what I've seen of her discography on her J-Wiki profile, the Tokyo-born actress has released many albums but only 4 singles up to 2016. From her 1985 album "Tiempo de Amor", here is "Watashi dake no Le Mans" (Le Mans Just For Me). Outside of the famous motor race, I know next to nothing about this French city, but from how Marimura's song sounds (shimmery light Latin Resort Pop with some jazzy highlights), it seems like there is a very pleasant high life there, although she is mentioning aspects of that race. Maybe it's like Monte Carlo?
Well, we'll just have to take a look, won't we? In any case, "Watashi dake no Le Mans" was written by Masako Arikawa（有川正沙子）and composed by Akira Okamoto（岡本朗）. Okamoto had a stage name earlier in his singing career, Issei Okamoto（岡本一生）, and he's got an entry on "Kayo Kyoku Plus", "Moonlight Singing".
