See The Verge article Japan's digital content struggles: the country of the future remains stuck in the past[0] for more on Japan's love-hate relationship with new technology.

Anecdotes like "A decade ago, Tamagoya tried to shift to online sales of its bento lunches, but business suffered" suggest to me that a digital interface to faxes using tablets (for writing) might be quite popular in Japan among those who do want to move away from faxes. Just because the person you're communicating with needs faxes so they get warm, fuzzy feelings while ordering their lunch doesn't mean your own business efficiency has to suffer as well.
