Maison Ikkoku: Shipwrecked on Ikkoku Island (1991)

Yotsuya and Ichinose reminisce about a time when Shun Mitaka, Yotsuya's suitor, took the tenants of Ikkoku-kan on a pleasure cruise aboard his new boat. After the boat breaks up, everyone is left shipwrecked on a desert island, where they must try to make the best of the situation. This animated short is an adaptation of a story from MAISON IKKOKU, a manga series written and illustrated by Rumiko Takahashi.

Unfortunately the movie Maison Ikkoku: Shipwrecked on Ikkoku Island is not yet available on HBO Max.
