In the early 1980s, I lived in Sendai. Back then I used to send photocopies of my corrected manuscripts to my publisher by postal mail. One photocopy cost me 40 yen (about 40 cents) per page. After the publisher received it I'd have to talk to them on the phone and discuss it. After a while this became a pain, so I moved to Tokyo by myself. Now faxes and color copiers are much better than they were back then. If they had been available back in the day, I doubt I would have moved to Tokyo. Lately I'm really seeing how times have changed.
