I borrowed this magazine from a friend long enough to scan it. I had no idea there was a Commodore Japan until I was in my 40s. By the time I heard about it, it was all from the lens of an unfortunate part of computer history. But at the time this magazine was published, things were very different so now I know a bit about it from the lens of a bright future. I sure wish I could have experienced this time period, even for just one day.

Update: commentor AndreaP has alerted me to the existence of Volume 5 of this magazine on archive.org. Thanks!
