Picture of Shibuya Station's glowing sign. Caption: "the famous Tokyo shopping district known worldwide as Shibuya will be changed in its official presentation from Sibuya"
Currently, Shibuya is officially supposed to be romanized as Sibuya, but in common usage including signage it is written Shibuya.
"Amid concern the divide between official rules and common usage is causing confusion, a subcommittee of the Council for Cultural Affairs deemed it necessary to consider the revision to improve communication."
Since they want to adapt the law to match what everyone is already doing anyways, no change is to be expected.
This reads that the official spelling is currently Aichi.
The Shibuya sentence is very awkward as well.
"Aichi will replace Aiti" doesn't add any clarity if it's breaking that logic. There's a reason why others also find this article hard to parse.
It's hard to parse because the Japanese system is itself a mess. The (former) official romanization rules say the name of this prefecture should be written Aiti but the official practice is to write it as Aichi because that's easier to teach to non-Japanese.
Consider that the romanization rules were (iirc) mostly originating from the ministry of education, but that ministries responsible for trade and tourism would naturally prefer to use whatever is easiest for foreign partners to deal with, and could lobby for exceptions since they're revenue centers rather than cost centers. Japan has both a professional bureaucracy under a parliamentary system and de facto one party rule, so (imho) there's much greater potential for policy balkanization of this sort.
As an example of text written by native English speakers that has these properties of being entirely logically consistent but clunky and difficult to understand, see the Second Amendment to the U.S. Constitution.
Yes, the whole point is that kunreishiki is not practically used so it doesn't make sense for it to continue to be the official way to romanize things and for it to continue to be taught in school when no one is using it.
English readers will more naturally expect the "before" to come first in a sentence, and then the "after", but in the article the "before" consistently comes at the end of sentences.
The government officially used the Kunrei-shiki romanization rules for decades (apparently, though this is the first time I've ever heard of it), but is soon changing to using the Hepburn romanization rules [which correspond to nearly 100% of romanized Japanese terms that anybody would ever have seen in the wild].
The "diagram" in the article doesn't help English-speaking audiences at all, so it's out of place in this article. It seems to have been lifted directly from some other source, and what's more it's kind of a badly-designed diagram to begin with: the header reads something like "change in romanization system", each of the green background terms are names, and under it on the left is that name romanized under the old system and on the right is under the new system... but the names of the systems are in the first data row instead of in the header row / a second header row. Just.. so confusing.
They also make textbooks for Japanese-language learners.
My Japanese isn't good enough to read the news at speed, but I can manage TV news; there's a lot of stories that don't show up in the Japan Times until a week later. They do cover major political, economic, and crime (if it's a murder) news in a timely fashion.
