What is needed in defining RZ-LGR•••

Within JGP–Define basic requirements and draft Japanese RZ-LGR(J-LGR)

Among C/J/K GPs–Coordination among CGP/JGP/KGP, whose languages
share Han characters, so that C/J/K-LGRs can live witheach other wrt. technically allowed strings for IDN TLDs

Globally–Confirm there are no critical issues from the perspectiveof “coexistence with other language LGRs”

Stakeholders, regardless of whether direct orindirect, must be consulted in meaningful ways

6What need to be done within JGP••

Decide what characters are usable in TLD strings
Decide which characters are defined as variants––e.g., 国 and 國 (viewpoint : pronunciation & meaning)• Same pronunciations and meaning (e.g., new form
and old form of one character)→ JGP decided that they are defined as NON-variants
after discussion and public consultation in Japane.g., カ and 力 (viewpoint : shape)•Katakana “カ” and Han “力”, which have almost identicalshapes→ 10 pairs of characters are defined as variants throughfield research with general public

What need to be done among C/J/K GPs• Decide what characters are defined as variants– Definition of variants must be coordinated amongC/J/K••

CGP and KGP wanted to define pronunciation-&-meaningvariants
JGP decided not to have its own definition of variants(except for 10 pairs of shape-variants)– CGP and KGP discussed and coordinated, andagreed on the definition of variants– JGP agreed to accept the variants defined by CGP
and KGP to be incorporated to J-LGR
