Why didn't software work for Japanese business purposes? Keep in mind the 80s and 90s were the peak of the Japan economy, and if they actually wanted a software system that could handle Japanese requirements, they had the resources to build it.
Where's the Japanese counter-part of Lotus 1-2-3 and Visicalc? Why didn't any Japanese firm make this software, or if they did, why didn't it become popular?
Certainly Kanji makes things a bit more complicated, but IIRC I've seen systems that mainly dealt with Hiragana and Katakana. It's a limited character set. Nobody says you need to use ASCII.
