When I was a kid I watched “Astro Boy” on cable television back in 1978. I was in elementary school and I grew up on a college campus because my father was a history teacher. In the dorm there was a common space for watching TV and when all the students were out I could watch channel 44 and they had Japanese shows. I watched Gozilla, Ultraman, and Astro Boy. I had no idea that I was looking into the future that brought me to Japan many years later.
