His Motorbike, Her Island (彼のオートバイ、彼女の島, Kare no ōtobai, kanojo no shima) is a 1986 Japanese romance film directed by Nobuhiko Obayashi, based on a 1977 novel by Yoshio Kataoka.

Produced by Kadokawa Haruki Jimusho, the film stars Kiwako Harada, Riki Takeuchi, Noriko Watanabe and Tomokazu Miura.

Takeuchi, in his acting debut,[1][2] plays a motorbike enthusiast who falls in love with a young woman (Harada) after teaching her how to ride.

One day, Koh arranges to meet Fuyumi Sawada, a young woman who wants to ride a motorbike.

One day, when Hidemasa declares Miyo a biker prodigy, Koh fears that she is destined to crash.

They say a woman on a motorbike swerved to avoid a hare in the road, and that she crashed into a truck and was killed instantly.

James Balmont of Another Magazine cited His Motorbike, Her Island as an example of a film with a relatively sympathetic view towards bōsōzoku, a Japanese youth subculture associated with motorcycles.

[6] Balmont describes Koh's Kawasaki motorbike as "more of a symbol for freedom than anarchy", and writes: "From the opening shots, in which the camera fetishises the bike chassis in close-up as the engine gently purrs and rumbles, the bike is a beloved object that brings Koh in touch with the resplendent natural surroundings of Japan's countryside as well as stoking a blossoming romance.

"[6] On 17 October 2022, Third Window Films released His Motorbike, Her Island on Blu-ray in Region B as part of the four-disc box set Nobuhiko Obayashi's 80s Kadokawa Years.
