When timid eleventh-grader and math genius Kenji Koiso is asked by older student and secret crush Natsuki to come with her to her family's Nagano home for a summer job, he agrees without hesitation.

Natsuki's family, the Jinnouchi clan, dates back to the Muromachi era (1336 to 1573), and they've all come together to celebrate the 90th birthday of the spunky matriarch of the family, Sakae. That’s when Kenji discovers his "summer job" is to pretend to be Natsuki's fiance and dance with her at the birthday celebration.

As Kenji attempts to keep up with Natsuki's act around her family, he receives a strange math problem on his cell phone which, being a math genius, he can't resist solving. As it turns out, the solution to the mysterious equation causes Oz, the program that controls nearly every aspect of life to be hacked into, it's up to Kenji and his new "family" to stop the hacker before it's too late.

There is only one word that can sum up this entire movie. Family. The whole concept of this entire movie revolves around being a cooperative and strong family. What does the word family mean to you? A group of people who are of same blood? This movie will show you the true meaning of family, a group of people who may or may not be of blood relation, but truly support each other till the death. That is what a true family is.

As one of the directors responsible for making Digimon: The Movie happen, I guess it makes sense for Mamoru Hosoda (also did The Girl Who Leapt Through Time) to infuse elements of his past work into future projects. Such is the case for Summer Wars, his latest and quite possibly his most ambitious film to date. Even if you’re not a fan of anime, you’ll find something to like in this sci-fi/comedy/romance spectacle that is both awfully heartwarming and very pleasing to watch.

As far as family entertainment goes anime is rarely high on the agenda, especially given the numerous offerings from Disney, Dreamworks, and other such movie studios. Generally their features appeal to children and adults alike, and in order to compete with them Japanese animation studios have had to shake off their habitual approach and focus on making films that are more accessible to Western markets. The undisputed king of this is Miyazaki Hayao, however there have been several challengers to his throne, the latest being Hosoda Mamoru.

Now those of you who have watched the latest anime incarnation of Toki wo Kakeru Shoujo (The Girl who read more

Summer Wars is a perfect example of a story biting off more than it can chew.

The film opens with an introduction to ‘OZ’. An information network that controls and monitors electronic services all over the world: from shopping to competitive gaming to healthcare facilities. Think the current internet age, but even more extreme.

Then we’re introduced to Kenji, a math wiz who works as a moderator for Oz and has a crush on a girl named Natsuki. A few moments later we’re introduced to this crush of his who begs him to come with her to visit her family’s summer home. Thus kicking off the read more

They both deal with people trying to save the world after a threat appears on the net. They also share the same director.

good drawing/animation, unique story, similar main girl character

The high tech community in both of these beautifully animated shows remind me of one another. The cell phone based social networking center is an all new way to communicate with people and eliminate modern day necessities. Both shows are very futuristic in a sense.  
reportRecommended by Nikoru-san
If you like stories about big networks through mobile phones and the net, you should watch these two.

Tsuritama and Summer Wars both have colorful, vibrant art styles and animation. Both also focus on bonds between characters, though Tsuritama deals with friendship while Summer Wars deals with family bonds. The suspense in both has the same feel to it, and both have to do with saving the world. The tone, atmosphere, and mood are also very similar in both.  
reportRecommended by red-exorcist
Both anime seems to share some notable common features including:

- sci fi theme
- battling as avatars in another world
- two worlds: the virtual and the real
- an independent and strong female protagonist
