Hokkaidō — the one true spelling, and the forms that fail it

Evidence dossier 112 — Hokkaidō. Every exhibit catalogued, every ruling stated with its grounds.

At a Glance

• Canonical form: Hokkaidō
• Original script: 北海道
• Pantheon: Japanese
• Convention: Hepburn with macrons — ō and ū marked, never collapsed to o/u or rewritten ou
• False forms on record: 2
• Contested forms: none attested
• Series: The Canonical Register, No. 112 of 287

The Evidence

Exhibit 1 — the attestation. The name is attested as 北海道, as Kojiki and Nihon Shoki preserve it. On the evidence, it means "Northern sea circuit". The canonical transliteration is Hokkaidō.

Exhibit 2 — the preserved marks. o → ō (Macron: long vowel). Each is verifiable against the sources named in the attestation.

Exhibit 3 — the flattened form. The plain form hokkaido is not false — it is a fallback, and the register is exact about what that means. In systems that cannot carry diacritics (legacy databases, older tooling, parts of the address-bar pipeline) the flattened form is the accepted vehicle, and the rulebook names it explicitly as the final rung of the fallback hierarchy: full restoration first, circumflex where attested, macron-only by the academic standard, an attested variant, and only then plain ASCII.

What the fallback status forbids is promotion: hokkaido may carry the name where marks are impossible, but it may not represent the name where marks are possible. Every mark it drops — o → ō — is a fact the sources recorded. A fallback is a vehicle, never the primary.

Exhibit 4 — struck from the record: Hokkaido. Origin: the publisher compromise — older books and hurried websites that print the "English equivalent" as if it were the name itself. Grounds: every substitution here (ō→o) is a romanization of convenience, not an attested spelling — it teaches the reader to guess, not to read.

Exhibit 5 — struck from the record: Hokkaidô. Origin: the near-miss — a form that looks right at a glance and circulates on wikis and forums. Grounds: a macron (length) is not a circumflex (quality/tone) — they answer different questions.

Exhibit 6 — the physical record. Hokkaidō holds some of the world's oldest pottery: Jōmon-period cord-marked vessels from sites like Taishō date beyond 14,000 years, among the earliest ceramic traditions on earth. The Shiretoko peninsula is a UNESCO World Heritage site for its marine-terrestrial food web; the Oshoro stone circles and the Ofuna shell middens mark the island's deep ritual past. Hakodate's Goryōkaku — the star fort of the last Tokugawa loyalists (1869) — is where the old Japan made its final stand on the new island.

Exhibit 7 — the continuing record. Hokkaidō supplies a third of Japan's food from a tenth of its land; Sapporo beer, the Snow Festival's ice palaces, and the lavender of Furano are national brands. The 2020 opening of Upopoy, the National Ainu Museum and Park at Shiraoi, gave the island's first people their first national institution.

The Convention's Own History

Every tradition in this register has its own scholarly transliteration standard, built by its own specialists over decades or centuries, and the register follows each on its own terms: Hepburn with macrons — ō and ū marked, never collapsed to o/u or rewritten ou. The principle that unifies them is the one the whole project stands on: a name is evidence, and evidence is not negotiable — not for keyboards, not for convenience, not for anyone.

The Protocol's Position

Can the canonical form live in the address bar? Almost always, yes. IDNA 2008 admits every mark this register defends — the DNS stores them as `xn--` punycode and modern browsers render them natively. The real frictions are practical, not legal: some registrars stock only part of the IDN space, so a theoretically valid name can be temporarily unbuyable; and stacked combinations (an acute riding a macron) remain awkward to type on mobile keyboards even where the protocol accepts them.

The project's answer is a ranked ladder, not a compromise: the full restoration first, then attested fallbacks in descending order of completeness. The ladder's lowest rung, plain ASCII, is a vehicle for legacy systems — sanctioned, but never presented as the scholarly form.

The Verdict

Case closed on Hokkaidō: canonical, cited, and defended. The keyboard form hokkaido rides as the sanctioned fallback — and stays in that lane. The register's files remain open: if a source surfaces that changes any line of this entry, the entry changes. Until then, the temple at /sites/hokkaido/ holds the canonical form.

The docket for this ruling: 2 false forms ruled against, Hokkaido first on the docket; 1 preserved mark verified: o → ō; no contested forms attested; the attestation rests on 6 cited sources — Kojiki, Nihon Shoki, Japanese folklore.

The Register Continues

The register holds 287 entries like this one — each temple with its own ruling. Read the temple's founding dispatch for the story, its Restoration File for the philology, its Resonance File for the industries, or the whole archive end to end.

The Canonical Register is written from the same canonical record as the lexicon itself. If a false form is missing from this page, it is because the evidence does not support calling it false — or because we have not seen it yet. Show us, with a citation, and the register will answer.
