Which seems a bit like “Japanese government to officially acknowledge gravity exists” since everything including almost all government signs are already in Hepburn. All the train signs in Tokyo use Hepburn, as did all the street signs. In fact, I can’t recall a single time I saw Kunrei-shiki when I was in Japan.
The ONLY time I’ve ever really seen Kunrei-shiki was in a Japanese language class in Pittsburgh back in 2006 that was using books in need of a revision and update.
