Nippon Telegraph and Telephone developed the Camellia ciphers:

http://www.ietf.org/rfc/rfc4312.txt

Advice is given that it is available for use in OpenPGP:

http://www.ietf.org/rfc/rfc5581.txt

The reason that it is there is because somebody (most likely
the Japanese) wants it and even my semi-old Linux distros have
it in older versions of gpg1 and gpg2

================================================================
$ gpg --version
gpg (GnuPG) 1.4.10
...
Cipher: 3DES, CAST5, BLOWFISH, AES, AES192, AES256, TWOFISH,
        CAMELLIA128, CAMELLIA192, CAMELLIA256
================================================================
$ gpg --version
gpg (GnuPG) 2.0.16
libgcrypt 1.4.6
...
Cipher: 3DES, CAST5, BLOWFISH, AES, AES192, AES256, TWOFISH,
        CAMELLIA128, CAMELLIA192, CAMELLIA256
================================================================

I updated my handy-dandy cheat-sheet for settings I got from
somebody else so you know their designations and can add them
into mix of ciphers with preference:

I will probably add Camellia-128 after TwoFish some place in
there among the AES ciphers and may even let it replace one of
them but will keep AES (AES-128).  So if you want to use one of
the Camllia ciphers use them in good health.

Let me know when Serpent is avaiable.
