Why isn't paperless going on in Japan?

Only earlier this year, the direction of paperless offices for the official bulletin, plenary session, and committee minutes was shown. This year is, of course, 2022.
Why isn't paperless going on in Japan? There are some considerations. The cultural aspect of traditionally valuing paper records, the aspect of industrial protection for the paper industry and copier makers, but that is not the biggest factor.
It does not ban or eliminate paper culture, art, or traditions, and the disadvantaged industries are diversifying and transforming. The biggest reason is the resistance of annoying people (mainly the elderly) and organizations (government offices) who refuse to change or innovate and sneak up on vested interests.
Just seven years ago, I was invited to consult with the Tokyo Bar Association, and I advocated paperless office as one of the themes of the year, and conducted a survey and report. From my business experience of more than 20 years, I was convinced from that time that there was no big problem in terms of both hardware and software, but the actual introduction was limited. It was about digitization of public relations media and distribution of materials in electronic files. Moreover, the latter was with the consent of the members. The reason for the paperless operation is that the court did not approve the electronic application, although there were resistances from the big lawyers who could not use the personal computer and did not want to use it. Five years later, in 2020, it was started by a part of the Tokyo District Court, and seven years later, it was followed by the Diet. One last surprise episode. The "FAX number" was mandatory and the "email address" was optional as a requirement for registration with the Tokyo Bar Association. What's going on now? There is no doubt that young citizens are the most advanced and older parliamentarians are the youngest.
