Latest JPRS reports on IDN ccTLD
Apparently they haven’t decided anything about the way to introduce new IDN ccTLD.
They say there are 3 options.
a) Give .jp registrants .日本, too;
b) Issue .日本 separately; and
c) Alias .jp to .日本.
The reports argue pros and cos of each option. It also says option c is probably unfeasible given technical difficulties.
