Doraemon The Movie: Nobita's Great Battle of the Mermaid King (ドラえもん のび太の人魚大海戦 Doraemon Nobita no Ningyo Daikaisen?), also known as Doraemon the Legend 2010, is a 2010 Japanese film based on the manga of the same name. The film was released on March 6, 2010.

As part of the franchise's 40th anniversary (and the 30th anniversary of the first Doraemon film), it was released in selected Singaporean cinemas on December 9, 2010 in Chinese.

Sadly, this movie has not yet been release in America, and despite the 2005 related series got an official English dub, the following related movies, including this movie, are not.

There are some Doraemon fans in English-speaking countries who want this movie dubbed someday.

So,  I hope Viz Media will pick up this movie someday, because this movie resembles "Disney's Little Mermaid" in my opinion.
