I'm liberating this one from the evil empire. The original poster recently saw this one at Nagoya, evidently one of the few-ish remaining ones in service. Their post title was:
Orange backlit LCD, check! Phone card slot, check! Japan in 1982 was the future! (An endangered species spotted at Nagoya station)

They're still around. The color will tell you if it can do international or only domestic. They are particularly useful in disasters when cell towers are jammed (or just down after battery back-ups start failing after 24-96 hours depending).
Are some of them pink?

You can click on the various year ranges, but there have been a variety of types over the years. I don't recall having seen an actual working phone that wasn't green (or is it more yellow? I'm mildly colorblind) and grey.
