I sent pull request japanese-update (see #871) .
but your travis ci had problem. it said that:
$ curl -sSf -o python-3.4.tar.bz2 ${archive_url} curl: (7) Failed to connect to s3.amazonaws.com port 443: Connection timed out Unable to download 3.4 archive. The archive may not exist. Please consider a different version.

please fix the travis ci environment .

AWS often fails. unfort. there's not much we can do about that besides restart the build. That fixed it.
