Kurama Mode is Naruto's name for the shroud he has when entering Tailed Beast Mode. Meaning Minato used Kurama Mode when he manifested Yin-Kurama, though it didn't look all that different from his basic Nine-Tails Chakra Mode, with just the slit pupils as an addition.

Naruto's Mode in The Last was not Nine-Tails Chakra Mode but Kurama Mode (combined with Sage Mode as well), since he had to manifest Kurama outside of his body.
