In season 2 of Tokyo Vice, they show character Jake, a reporter for newspaper Meicho Shimbun, using a native Japanese “word” processor to type in his stories. Really fascinating and seems to be authentic.
I remember being absolutely fascinated by the ability of 1980s/early 1990s Japanese laptops to manage input with a standard keyboard. Especially given the computing resources of the time, it seemed like serious dark magic.
The first time I watched battle royal I thought the hacking scene was film magic, because no way could the computer just change letters into Japanese characters like that.
Unlike Jake (Adelstein) himself, who whenever I've read any of his stories has obviously made it up. Especially the ones where he claims to know everyone in the yakuza.
