As I mentioned in the article for Anzen Chitai's（安全地帯）"VIII ~ Taiyo" album from 1991, I think Koji Tamaki's（玉置浩二）band started losing their appeal for me with "VII ~ Yume no Miyako" in 1990, although I liked a number of their tracks on that later album. Since then, it hasn't been quite the same so for me...Anzen Chitai was more the band of the 1980s.
Having said that, listening to the band's 22nd single from December 1992 "Ano Koro e" (To That Time) is a wonderfully moving experience, thanks to Tamaki's incredible voice. It's a well-titled ballad since the music and vocals easily brings me back to the time when Anzen Chitai was one of the top bands in Japan.
As usual, it was Goro Matsui（松井五郎）on the lyrics and Tamaki on the music. "Ano Koro e" sounds as if it were a love letter by the band to their home in Hokkaido. A big sloppy heart is on everyone's sleeve as Tamaki starts off with words like these:
The snow falls in my faraway hometown
They become tears of nostalgia
I wait for the spring. My memories
Can probably make someone happy
That sky, those winds
They still unfailingly stay in my heart
If I can take you
To that heartwarming time someday
If I'm not mistaken, I think the song was actually used as a campaign song for tourism somewhere, probably Hokkaido itself. "Ano Koro e" could sell it. Tamaki makes the whole scene epic and intimate at the same time right down to the keyboard putting forth those sounds of snowflakes falling softly.
I don't think the ballad ever made it onto an original album but it did get onto at least one BEST compilation since that is where I first heard the full version. Anzen Chitai's best days may have been behind them by the early 90s but the band could still come out with the one big amazing tune. And Tamaki will go down as one of the best singers that Japanese popular music has ever seen.
