I looked at the number of dot jp registrations on the Japan registry page. http://jpinfo.jp/stats/domains.html There are about 500,000 dot jp registrations of which 122718 are IDN (日本語ドメイン) domains. Already about 1/4 of dot jp registrations are IDN domains. I have a feeling that by this time next year the number will be between one third & half.

Most of the new registrations are various Japanese companies & even the registries themselves grabbing up the valuable domains before the common person realizes IDNs can be used. I know that many probably think that non Japanese own most of the IDN dot jps but that’s not true. I think we represent less than 5 to 7% combined. Japanese companies like Recruit, Pia, Daiwa, Sony, & other private companies that have 50 to hundreds of the best Japanese commercial terms each.

There are also quite a few Japanese individuals who are collectors. Some of them collect only certain types of IDN domains in jp. I saw one guy who only registered single character kanji domains. The way I saw his collection was he beat me to a drop I wanted.

Here’s a good one
