It is
bubble-era Japan. Kensuke Sugimoto, a
bodybuilding instructor at a gym, has been married for two years. His wife, Fumiko, works as an office administrator at a
listed company. Kensuke's fellow instructors at the gym, Yukari, Saito, and swimming instructor Sasaki, are all friendly, and Kensuke likes his co-workers. Kensuke and Fumiko enjoy elegant conversations and go out to dinner together. In spite of this, they lead largely separate lives, though they accept and respect each other's chosen paths. One day, the couple head to a misty
Hakone villa in their beloved
Chrysler Cordoba. Kensuke's long-held dream is to purchase a
Harley-Davidson motorcycle; he plans to do so after they reach their destination. However, Kensuke discovers that their shared bank account has a zero balance when he tries making the
down payment. This is due to Fumiko's
spendthrift habits. He scolds Fumiko, as this isn't the first time this has happened (things have gotten to the point where Fumiko now has 31
credit cards). Nonetheless, they make up, though the incident puts a strain on their relationship. Fumiko gets a second job as a
hostess at the Katsura Club for extra income. She quickly attracts the attention of the customers. One day, the owner of Katsura introduces her to a customer who wants to pay to have sex with her. When she tells Kensuke, he consents to the arrangement. Kensuke drives Fumiko to a hotel, where she has sex with the customer. Fumiko becomes a popular
sex worker at the club, and soon has enough money to buy whatever she wants. Their life together continues as before, but a sense of emptiness grows in Kensuke, and he reflects on their relationship. At the same time, Fumiko starts to tread in the footsteps of her husband, learning more about him and what he enjoys. One day, Kensuke suddenly breaks up with Fumiko. He says he is going to travel around Japan on his motorcycle. Though initially shocked, Fumiko agrees to let Kensuke go. Kensuke sells his apartment, then buys the long sought after Harley-Davidson from his childhood friend, Nakamura. On the day of his departure, Kensuke has sex with Fumiko in their Cordoba. Afterwards, he drives her to Oi Wharf, where he says goodbye and sets off along the gulf road. Fumiko, left behind, feels frustrated with life. A month passes with no word from Kensuke. Fumiko learns how to ride a motorcycle with coaching from Nakamura and his wife, Catherine. A year later, Fumiko quits her job and, like Kensuke, sets off along the gulf road on her own Harley-Davidson. ==Cast==
