So this is for the Mix only, and you need to have a Bandai Namco ID in order to use it. (Luckily they're free and have an English registration process.)
For the family tree itself, there's no English option, sadly.

To use it, after naming your family you add generations via passwords on the Mix once your Tamas have reached their Adult/Friend stage. If you have a Mix and figure out registration, I'm happy to guide you through the rest.
