Japanese companies and organizations (and people) love diagrams to present to the public. Whether how to navigate a website, book a ticket, check-in to a hotel, etc. the number of process diagrams in daily life (as a perceived effective way of communicating information) is unseen outside Japan.
Also, the amount of highly detailed posters in public places. For example, the departures board of a train line -- far more information than probably the average US rider knows how to comprehend even. Or is interested in.

You have to wonder whether this generates a tolerance or expectation that detail is expected to be understood.
