Both stories involve a friendship between a kind-hearted human and an innocent fish (taking on the appearance of a human). Ponyo is about an innocent love between two children, where Tsuritama is about creating friendships and working hard to understand each other.
-Perfect vibe for summer break!--heartwarming and happy seaside fun
-fish, that are people, that are actually fish, that are really treasured friends (@_@) fish are friends, not food?
-Beautiful scenes centered around the magical, mystical ocean,
-and protective fathers
-friendly, welcoming mother figures
-flooding of a village
-being lost at sea
-being friends forever
Both are light-hearted with nice colour palettes, set close to the ocean, and about a friendship between a human and a fish taking the form of a human (strange as that sounds) They're both nice and short to watch when you feel down, though Tsuritama is a 12 episode series while GUP is only a movie.
- Both about a relationship between a male human kid and a childish female sea creature.
- Both contain warm and colorful visuals.
- Both films have a family atmosphere.
- Both Events happening in a town by a sea.
Both are family friendly films that take place by the ocean (and happen to be directed by phenomenal people).
Both films feature a cute & fun-fulfilling relationship between a male (child aged in Ponyo & older teen aged in Lu) and a female aquatic entity, who they become positive influences within both protagonists respective lives.
Both have individuals that think differently about the balance and laws between their respective lands and species (humans and sea creatures).
Both sea heroines happen to have really cool fathers. Although they may look a lil’ spooky and sometimes do what may seem like spooky acts, but in actuality, they are both kind beings, have justified reasons and do nothing wrong.
Both share overall themes with a few differences, Ponyo is more adventurous and has the nice traditional Hayao Miyazaki/Studio Ghibli look, while Lu is more musical/coming of age based and has an unusual, yet sweet art style (being by Masaaki Yuasa).  read more
If you enjoyed Yoake Tsugeru Lu no Uta, I am most certain you will definitely enjoy Ue no Ponyo.
The themes that are set for the movies are quite similar. They are both light-hearted stories about friendship mainly revolving around the sea. You could say that they give of the same vibe. The same thing goes for the adorable fish-like characters with "magical" powers. And the, of course, not to be forgotten beautiful flowing animation which is pleasant for ones eyes to view.
Ponyo and Spirited away are very similiar when it comes to the overall feeling. Its very cute and mysterious. And you really love the maincharacters in both. While Spirited Away is a bit more serious both are very lighthearted anime movies. Also Studio Ghibli made both.
Ponyo consists in a plot aimed at a younger audience while Nagi no Asukara's targets the older, but both display some similarities:
- Beautiful sceneries and unique animation.
- The heroine is from the sea and is in love with a human. The story takes place when she is fished by the human boy.
- There is a kingdom underwater where mystical beings live like a god/goddess who are able to cast curses.
While Ponyo focuses on friendship, fantasy and adventure, NnA centers itself in a love polygon and is able to give more depth to the characters.
If you liked one and enjoy the theme of "little mermaid" spin-offs, you might enjoy the other.  read more
all of miyizakis fantasy work is very similar to mushishi, aswell as the natsume yuujinchou series. Also if youve already seen the above mentioned then i would also watch both seasons of moyashimon, its got a very similar wabisabi effect based around simplicity and the mysterious beyond.
Both are very cute anime movies, great for children but also enjoyable for adults. They are heartwarming, with great art. Major difference is that Leafie IS SO EMOTIONAL. If you want a good type of cry, watch Leafie.
Both feature idilic locales of a seaside town. And a magical person of ancient lineage who wants to follow their own path against the wishes of their mentor, and that person being influenced and changed by the experiences of a normal, mortal life. The visuals, especially the magical effects, are a sight to behold in both.
Both are very kawaii and directed by the famous Hayao Miyazaki. Castle in the Sky and Ponyo on the Cliff by the Sea both have that classical feel and same art style with the two lead characters as a boy and a girl. Ponyo by the Cliff by the Sea is a bit more on the childish side, while Castle in the Sky has a deeper meaning and story.
This may just be IMO but... there ARE some similarities. The endings are different (obviously) but, if you look at it like this, IMO, you will see the similarities

So... yeah... do whatever you want
I don't know how to explain, but the feelings after you watched these movies are somehow resemble each other, so... I'm sure it won't be just a waste of time, if you'll watch it. Actually, The Cat Returns is more interesting.
