The perennial domain debate in the Japanese market. The flexible .jp versus the corporate-only .co.jp.
The general-purpose JP domain for the Japanese market. Available to individuals. A staple for domestic services.
May require rebranding when expanding internationally.
Observer's Note
An endemic species of the island ecosystem. Perfectly adapted to the distinct niche of Japanese-speaking users.
Restricted to Japanese corporations. One domain per organization. The strongest trust signal in Japan.
Requires legal corporate status. Strictly one domain per entity.
Observer's Note
Armored like a fortress. Only those bearing the credential of corporate personhood may don this shell.
