Japan Just Made Hepburn Romanization Official — 158 Years After a Missionary's Dictionary
Hepburn Romanization: How to Read Japanese in the Latin Alphabet
In December 2025, Japan designated Hepburn romanization as its national standard, ending roughly seventy years of conflict between the official Kunrei-shiki system and the practical Hepburn system used on passports, road signs, and textbooks. The system, popularized by American missionary James Curtis Hepburn's 1867 Japanese-English dictionary, prioritizes English pronunciation over systematic kana mapping—writing し as 'shi' rather than 'si.' The change aims to reduce inconsistencies in how Japanese names and words appear worldwide.
The system the world was already using is now the system Japan officially recommends.

As someone intimately familiar with this topic, the article here is mostly correct but gets a lot of the small details wrong.
Probably the most important missing part here is the reason non-Hepburn systems like Kunrei stuck around for so long: they were designed to replace the Japanese script completely. This sounds outlandish today, but they were invented during the early Meiji years when Japan was adopting Western innovations and abandoning ancient traditions at breakneck speed. And because their target was thus Japanese people, not foreigners, they didn't need to worry about English phonology.
Incidentally, the Chinese pinyin system was also designed to replace Chinese writing, and Mao came quite close to abolishing Chinese characters entirely during the Cultural Revolution. Which also explains why it uses letters like x, c and q in ways that English readers find wildly unintuitive.

> Kunreisiki is also better for serious Japanese learners as it greatly simplifies the description of Japanese grammar: cf. matu/matte/matimasu (all with the same verb stem mat-) vs. Hepburn matsu/matte/machimasu (with 3 different verb stems)."
This is a silly argument because anyone learning Japanese is going to need to learn how to pronounce it anyway. Also "serious Japanese learners" would likely be using kana.

Yes, several things are just wrong here, e.g.
"…久保 becomes "Kubo" without the long vowel marked at all…" -- there is no long vowel! Just plain Kubo is correct.
"Nihon-shiki and Kunrei-shiki optimize for a systematic, one-to-one mapping between kana and romanization. One kana, one romanization, always, with no exceptions."
(Kunrei-shiki: exceptions! 猫は庭へ魚を運ぶ Neko wa niwa e sakana o hakobu)
Also: "Romanization is a scaffold, not a destination." ? I TOO AM A HUMAN WRITER WHO WRITES WITH MY OWN FINGERS.
But the history of the Romaji movement is indeed interesting - there were influential people who were quite serious about moving entirely to romaji at one point! It would have changed everything.

If any aspiring Japanese learners read this, forget this article. Just start learning hiragana/katakana from the get-go. You’re going to have to eventually, assuming you want read anything (and anything worth reading certainly won’t be written in romaji). But beyond that, you want to start breaking down your instinctual pronunciations and biases that appear when reading letters you know, so that you can more accurately and efficiently learn the correct pronunciations.

Minor correction on the article: Kunrei-shiki doesn't have a 1-to-1 mapping between kana and letters. You can see that directly in the table they show. Only Nihon-shiki does. Kunrei-shiki is the worst of both worlds.
That's why Nihon-shiki is and will likely always remain the best system for serious students of Japanese - if you even need it at all. But then again, if you're just starting out, the best place to start is usually to immediately start learning kana.
