Like with a lot of things like this, if you learn for long enough the differences in the major approaches work themselves out.
In the last 10 years in Japan, more and more goverment documents are now available with furigana. Sometimes the edition is called "Friendly Japanese" (yasashii nihongo / やさしい日本語). The best explaination I can think of: There has been a dramatic rise in the number of non-university-educated foreign workers who have come to Japan on labor contracts -- factory workers, farm workers, hotel staff, shop staff, etc. They need to live their daily lives in Japan, but will struggle with native-level Japanese documents, so the gov't (both national and local) make an effort to reduce this friction. I expect the level of support from local gov'ts will be very much correlated to the number of foreign workers in their districts.
