No, Basque is a language isolate with no obvious related languages. I don't think it is even Indo-European, like all other European languages. Breton is related to Gaelic, though, and that might be what you are thinking of.
There are a lot of similarities in the language of the Ainu an Aryan-looking tribe which migrated across Asia to N. Japan about 7000 years ago. There are about 17000 remaining today concentrated on Hokkaido.
