There was also a drink with same name hiropon that was generally available for some time.
I tried googling for more info but I haven't been able to find much in English and my Japanese isn't good enough to read at that level. I've only heard about it from my wife and a few other people in Japan. I've seen a few old posters for it at old bars.
