Japan: Avatars come to life in the anime Summer Wars

Against the background of the Japanese countryside, feel good sentiments and an extraordinary virtual world are featured in Summer Wars (サマーウォーズSama wozu) [ja], the new animated movie by director Mamoru Hosoda [en].

The anime tells the story of Kenji, an awkward teenage math genius who finds himself involved in an epic battle in a virtual world where he must become a code breaker and battle avatars to win. His allies are the members of a traditional, old-style Japanese family.

Summer Wars [en], created by the award winning director and screenwriter, was received very positively by the Japanese public and topped 1 million viewers in the first few days after its release this summer.

MoriGuru particularly appreciated the mix of different elements and the family values that the film conveys.


The message is a universal one like ‘the bonds among human beings are important’ but the integration of elements such as the large family and the imaginary ‘virtual’ world created a particular matrix.
To be honest, in the beginning I thought ‘this movie is going to be light weight’ but, as the story developed, all of a sudden it warmed up and that uncertain feeling in me faded away.
When the movie was over, it left in me a good sensation and I think that it was well worth watching it at the cinema.
I also thought how nice would be having a large family even though it might be rowdy!

Taka also praises the anime and describes elements that he recognized in his own life.


As I watched it I found a lot of common points with my own life and I felt very involved, emotionally rather than just rationally.
These are some of the common elements:

  • I am also from Nagano Prefecture (Summer Wars is set in Ueda, while I am from Ina)
  • Every summer, my cousins from Tokyo came to my home in Nagano. They stayed over and we have a lot of fun altogether.
  • My family is a female lineage family
  • My granny passed away this spring
  • In our family, we also celebrate a birthday on the day of Sakae's (Summer War's grandmother) birthday of August 1st
  • The movie has received also some criticisms, however. The ‘teenager saves the world’ scenario, in particular, has made some [ja] consider the story too light weight to claim a special place in the viewer`s heart.

    Blogger at Kz Loghouse feels somehow unsatisfied at the sentimental scenes.


    There are a lot of moving scenes and some of them reach straight to the heart.
    Though there are these…. I feel that there `s something missing…
    As example, it`s that kind of sensation like ‘yes, tears come to my eyes but I`m not feeling real grief.’

    Summer Wars was first released as a manga to test people`s reactions and kazahoshi ranks the written version.

    In some parts the book is different and the ending was completely different.
    In conclusion though, the movie has no rivals!

    • I’m very surprised to find that my blog entry is referred by this kind of English media. Thank you.

      One of the factor that many Japanese people like this movie is that, we are longing for family ties, because the number of two-generation families are increasing recently, especially in urban area like Tokyo.

      I like this movie, and there are many fans of it around me.
