A chance meeting on a train to Tokyo sends two girls named Nana on a collision course with destiny!Nana "Hachi" Komatsu hopes that moving to Tokyo will help her make a clean start and leave her capricious love life behind her. Nana Osaki, who arrives in the city at the same time, has plans to score big in the world of rock'n'roll. Although these two young women come from different backgrounds, they quickly become best friends in a whirlwind world of sex, music, fashion, gossip and all-night parties! Anxious to get into a Tokyo groove, both women are on the prowl for a funky and cheap place to live.

But inexpensive apartments in Japan's capital city are hard to find. Thank goodness each Nana has a clique of cool friends willing to help out. Too bad these friends are a little wiggy!
