What is Soka University known for in research?

The fields where it stands highest, 2022-now, ranked among every institution above the floor in each field.

FieldWorld rankWhere that sitsTop-10% rateWorksAll time
Physical SciencesDomain #8,441 of 10,670 2.8%159 #12421
Social SciencesDomain #7,855 of 9,585 5.5%104 #10605

Each strip is that field's whole ranked pool, with the notch where Soka University sits in it, in the colour of the band that rank falls in. The track under the rate is the rate itself: it carries no average mark, because the average differs by field (from about 6% in Dentistry to 21% in Economics).

Which of those standings moved

The same fields on both windows: where it stood over the whole record, and where it stands in 2022-now. The distance is the story, and it is the one thing the two rank columns above cannot show.
