Japanese (and other language) test vectors are missing
vectors.json only contains English wordlists.
Considering this is the reference implementation it would be handy to have a reference set of tests. There are Japanese test vectors listed in the BIP39 document, but it would be good to see the reference implementation be useful as a complete reference.
TBH i was never fond of localized wordlists. Feel free to send a pull request adding other wordlists and test vectors.
Is true sorry about that thank for your help
