"Santa Fe" is historically significant for pioneering the (hea nūdo) genre in Japan.

There was only the adobe earth, the piercing blue sky, and Rie.

In 1990, she was the top female commercial talent in Japan, representing nine companies with contracts worth up to 60 million yen each.

In 1991, Rie Miyazawa was not just an idol; she was the idol. Having debuted in the mid-1980s, she broke the mold of the cute, subservient seifuku (school uniform) archetype. Miyazawa was sharp-tongued, intelligent, and possessed a striking, unconventional beauty. She was often called the "bad girl" of the idol world because she chain-smoked, dated older men, and spoke her mind on television.
