The Authentic Orthography
Sacred Site, Tochigi · Sunlight
Why nikkō.com is the correct form
日光
The name in its original Japanese form. A name that carries the full phonetic weight of its source tradition.
NIKKO
Stripped of its identity, the name was reduced to plain Latin letters. The original orthography — stress, length, breathing — was erased by systems that only understand A-Z.
Nikkō
The Unicode restoration recovers what ASCII destroyed. This is philological accuracy — not decoration. The domain encodes to Punycode, but the browser displays the truth.
nikkō.com → xn--nikk-o3a.com
The non-ASCII characters in Nikkō are encoded while the ASCII remains visible. To the DNS, it is Punycode. To humanity, it is Nikkō.

Why Nikkō is classified as Tier-1 Macron-Preserving
The Japanese original 日光 contains both stress AND at least one long vowel. However, there is only one historically valid Unicode restoration. The ASCII fallback is modern English, not ancient canonical. This is the full scholarly orthography — a single-tier Tier-1 name.
