From tu to tsu—cue the chaos
Japan to revise romanization rules for first time in 70 years
Japan swaps “Kunrei” for “Hepburn” — the internet splits between “Finally!” and “How do I type ō”
TLDR: Japan plans to replace its old romanization rules with the more common Hepburn style, reshaping textbooks and signs. Commenters cheer the clarity, bicker over “shi vs si,” gripe about typing macrons like ō, and joke that searches and game ROM hunts might get messier—because this change touches everyday reading and naming
Japan just moved to make Hepburn the official way to write Japanese in Roman letters for the first time in 70 years, and the comments section is a rollercoaster. Many are stunned this wasn’t already the rule, with one voice saying Hepburn simply sounds closer to how people speak. Another adds a spicy twist: Kunrei’s si/zi/tu might make more sense to Mandarin speakers, sparking a mini East-vs-West-ear debate.
The practical crowd crashes in next: long vowels like “ō” are back in the spotlight, and typing that little line (a macron) is a whole saga. One user groans that on Windows “you really have to work for that ō,” while others note phones and Macs make it easier. Meanwhile, gamers are cackling/crying: one joked this will make finding specific Japanese game ROMs even more annoying. Add a drive-by reminder that Thailand’s signs are all over the place, and you’ve got a chorus chanting for standardization before chaos reigns.
The plan: swap ti/si/zi/tu to chi/shi/ji/tsu, double consonants like “teppan,” and write long vowels with macrons (kāsan) or doubled letters (kaasan). Names can do their own thing. One commenter even linked a previous thread for the lore here. Textbooks are next—prepare for ō-mageddon and the great “shi vs. si” rematch.
Key Points
- •Japan’s Agency for Cultural Affairs proposed replacing the official Kunrei romanization with Hepburn-style spellings.
- •This would be the first overhaul of Japan’s government romanization rules in 70 years (since 1954).
- •Approval is expected within the current fiscal year, with gradual rollout in textbooks and other materials.
- •Hepburn examples adopted include chi/fu and shi/ji/tsu; guidance includes doubling consonants and using macrons or doubled vowels for long vowels.
- •Personal and organizational names may retain their preferred spellings; the review began in 2022 and was formally requested by then-minister Masahito Moriyama last year.
