The article seems to be missing what I think is the major reason why Japanese websites are how they are.<p>I think one of the major factor is how the IT industry works in Japan, and the process to build a website, an application or anything which involves software engineering.
A good majority of Japanese websites are not built or controlled by the company, but rather by what they call "System integrators", which they refer to as SIer, and these are quite different from the software/design agency we see in the US or in Europe.
The usual flow is something like<p>- Company A wants to build a website
- Company A talks to the SI company B
- Company A and B spend hundreds of hours doing meetings
- Company B's "System Engineers" write tons of specifications on Excel
- Company B asks company C to actually code the specification written on Excel
- Company C may then again delegate part of the system to company D, and this can a few more levels down depending on the size of the project<p>As nobody actually does the "building the service" part in company A or B, they usually do not have any designers, and therefore cannot give enough design related information to the company actually implementing the software.
However, the only incentive for company C being to get paid by company B, the quality of the work or the UI/UX does not really matter that much as long as it fulfills all the specifications written on Excel.<p>Now, some companies are starting to see that this model is quite flawed, and either recruiting engineers and designers of their own (e.g Recruit, a huge company in Japan owning many different webservices [1], has put a lot of efforts recruiting engineers and designers these past years). Some other companies start choosing companies which are closer to the software/design agency model - companies who actually do the engineering and designing part - but the SI model is still prevalent [2].<p>[1]: <a href="http://www.recruit.jp/service/" rel="nofollow">http://www.recruit.jp/service/</a><p>[2]: <a href="https://www.jisa.or.jp/Portals/0/report/basic2015.pdf?20160205" rel="nofollow">https://www.jisa.or.jp/Portals/0/report/basic2015.pdf?201602...</a> (p14)
