The song was released in March 1993. At that time, I was in the middle of my 3 years back in Toronto...between my Gunma and Tokyo stints. The Japanese-Canadian Students Association at the University of Toronto had a weekly Wednesday program of showing Japanese dramas at the International Student Centre, and one of the popular shows for the folks who came out (undergrads, Japanese working-holiday visa students) was a medical drama, "Furikaereba Yatsu ga Iru"(振り返れば奴がいる....If You Turn Around, You'll See Jackals). Starring Yuji Oda and Ken Ishiguro, the pair played rival doctors at a hospital; Oda played the embittered surgeon with a past. "Yah Yah Yah"was the theme song for the program, and Ryo Aska（飛鳥涼）even helped out with the score for the episodes. The song was an often-heard tune on those Wednesday nights.
As you can see on the video above, "Yah Yah Yah" is a real crowd-pleaser. And Chage & Aska get everybody jumping when the refrain gets screamed out and the winds blow through their trench coats. You can even bring your own "Yah Yah Yah" kit to karaoke. Just make sure you and your mate wear those coats, and bring along a small electric fan to plug in.
The song became the No. 1 song for 1993, and sold at least 2 million copies. And in the history of Oricon, it is currently the 11th-ranking hit. It is also on the duo's 16th album, "Red Hill", released in October 1993, which also enjoyed its time at the top of the album charts and was ranked 8th overall for the year.
Above is the opening credits sequence for the drama with Ishiguro and Oda running on the beach. For such a dark drama, "Yah Yah Yah"just seems so atypically up-with-people. And if you look at the complete sequence, Chage and Aska themselves show up for a few seconds. In retrospect, it's strange seeing Oda as a villain of sorts considering that a few years later, he would take on the character of his career, the fecklessly idealistic Detective Sergeant Shunsaku Aoshima in "Odoru Dai Sosasen"（踊る大捜査線...Bayside Shakedown).
