The Box Office Mojo website is listing the Ocean Waves anime film with a December 28 theatrical release date from distributor GKIDS.
The distributor recently released Only Yesterday for the first time in North America; the film was included in Tokuma Shoten and Disney’s distribution deal but never released.
Optimum Releasing released the Ocean Waves special on DVD in the United Kingdom in 2010, and Madman Entertainment released it on DVD in Australia later that year.
Central Park Media (CPM) and later ADV Films and Sentai Filmworks released Grave of the Fireflies, but Ocean Waves has never been released on home video in North America.
