It's possible there are a few reasons for this:
* Misspelling: The title might be slightly misspelled. Try searching for different variations, like "Eien no Once More", "Eien no Once Again", or variations in the year (e.g., 1983 or 1985).
* Translation: The title might be a translation from another language. If you have the original language title, it might be easier to find information.
* Limited Release: It could be a film that had a very limited release or is not widely known.
To help you find the movie you're looking for, please provide more details if you have them, such as:
* Original language title: If you know the title in another language, please share it.
* Genre: What kind of movie is it? Drama, comedy, action, etc.?
* Plot summary: Do you remember any details about the story?
