This language table is developed for the implementation of Japanese IDN registrations at the .ASIA gTLD in coordination with JPRS (Japan Registry Services), based on the JPRS Japanese IDN Language table (jp-JA: http://www.iana.org/domains/idn-tables/tables/jp_ja-jp_1.2.html).
DotAsia is committed to maintaining the integrity of .ASIA IDN registrations and understands the multilingual nature of the .ASIA zone as a gTLD. Unlike in the case of ccTLDs (e.g. for .JP) where only Japanese IDN registrations are expected, both Chinese and Japanese IDNs are expected for the .ASIA domain. There is an overlap between the character repertoire between the Japanese and Chinese IDN scripts, more specifically, Kanji characters used in Japanese can also be found in Chinese. This means that it is possible that a Japanese IDN consisting of Kanji characters only can appear to be a Chinese domain name for a Chinese .ASIA domain name user.
In light of the context of the .ASIA registry as a gTLD, this Japanese language table will also integrate the CDNC (Chinese Domain Name Consortium) IDN Language tables, based on the CNNIC (zh-CN: http://www.iana.org/domains/idn-tables/tables/cn_zh-cn_4.0.html) and TWNIC (zh-TW: http://www.iana.org/domains/idn-tables/tables/tw_zh-tw_4.0.1.html) tables, and consolidated for the .ASIA (ZH) Chinese IDN Language Table: (http://www.iana.org/domains/idn-tables/tables/asia_zh _1.0.html)
This language policy also incorporates the "Guideline for Japanese domain name zone administrators" from JPRS Japanese IDN Language table http://www.iana.org/domains/idn-tables/tables/jp_ja-jp_1.2.html by reference herein.
The following table uses the RFC3743-defined format, and is in compliance with the ICANN Guidelines for IDN registration and for publication in the IANA Repository of IDN Practices.
