I have no idea if/how Takano is credited on this album, but
two of Monster Hunter 3's composers are listed in the special thanks section, so I think it's entirely within the realm of possibility that Takano made a small contribution to the soundtrack.
I don't know if it's accurate (several MH albums have track commentary by the composers), but this page says track 25 was by Takano:
