I think that the situation of Camellia in Japan is similar to that of AES in US
or SEED in North Korea.
Camellia is developed by Nippon Telegraph and Telephone and Mitsubishi Electric
(both are Japanese companies), and included in "Japan e-Government Recommended
Ciphers List" by CRYPTREC (Cryptography Research and Evaluation Committees, Japan).
Of course, Japanese people can use AES and any other ciphers, however, Japan
Government and some Japanese people may prefer Camellia than AES (as I set key
pref to "CAMELLIA256 AES256 CAMELLIA192 AES192 CAMELLIA128 AES CAST5").
Camellia is also recommended by NESSIE in EU, and supported by TLS/SSL (RFC
4132, 5932, 6367), S/MIME (RFC 3657), IPSec (RFC 4132, 5529), etc.
