Doraemon: Nobita's South Sea Adventure (ドラえもん のび太の南海大冒険 Doraemon: Nobita no Nankai Dai Bōken) is the nineteenth installment of the Doraemon feature films and adapted from the Daichōhen Doraemon story of the same name. It is an expanded version of the chapter, Southern Sea Adventure, which was featured in the original manga.

Nobita and Doraemon set sail for a treasure island, but somehow they travel back in time! Separated, they face real pirates and a dangerous secret.

The search for documentation about the sea for a school work will make the magic door of Doraemon open and take Nobita to Shizuka, Gian and Sueno in the deep ocean. This time our friends embark on a huge and unique boat in order to learn about the mysteries of the sea and look for treasures. What nobody imagines is that a distortion in the line of space-time will lead them to the seventeenth century amid a great storm that will make them wreck and where Doraemon loses its magic pocket. No time to lose, our friends must find a way out. Will they succeed?


The film starts with a group of pirates searching for treasure. They enter a cave behind a waterfall and start crossing a bridge when suddenly it falls and some of them fall off. The remaining people continue forward and find the treasure at the centre of a pool. While swimming across they suddenly vanish and their ship also vanishes. A small boy shouts for his father who is gone for the treasure.

  • This is one of the two movies which use a special version of Doraemon no Uta for the opening, the other being Doraemon: Nobita's Legend of the Sun King.
  • This is the first film to be natively animated in 1.85:1 widescreen, instead of being animated in 4:3 and being shown with a soft matte in cinemas.
  • Despite its high reception, this movie is considered one of the worst Doraemon movies ever created and received many negative reviews from the fanbase, mainly due to the fact it wasn't written by Fujiko F. Fujio himself, how Nobita and his friends acted completely out of character throughout the movie, and the overall story tone being more childish compared to previous movies.
  • In late 2014, Disney XD Asia produced and broadcasted an English dub version of this movie.
    • In the original Japanese version, the pirates were speaking English. However in this dub, the pirates were speaking Spanish instead of English.
  • 20 years later, a second pirate-themed movie called Nobita's Treasure Island was released on March 3, 2018.
