So I was excited for the university Pikmin to come out. I was able to get one from the university I went to for my masters degree. Also in town is a medical school campus I attend. I was surprised to see it does not register on the radar as a university. I have had it marked on OSM for several years now, and it even has university in its name. Why would this one not count?
I am not sure about the situation in foreign universities, do they have hospitals on their medical school campuses?
Pikmin Bloom has several that are not allowed as POIs. For example, there are no airplane pikmin from the Air Force base, and it seems that planting flowers on the road right outside is not allowed.
Similarly, hospitals are not recognized and do not generate POIs around them. For example, there was a time in the past when Lawson (convenience store) was a sponsor in Japan and special items were distributed, but Lawson in the hospital was not shown.
Also, there is a large post office next to the hospital near ours, but it does not show up either.
In addition, there is a FAQ regarding locations that do not display [Reporting In-game Locations — Pikmin Bloom Help Center].
Some medical schools in America are near hospitals and it is not typical for them to be physically part of the hospital. This one specifically is not near one at all.
I have seen flowers and mushrooms at hospitals in California, attached to outdoor sculptures.
