Summer Wars Plot

In the not-so-distant future, the virtual world of OZ has become a global phenomenon. Connecting to the internet, OZ offers a space for people worldwide to engage in various activities, from sports to shopping, using avatars they create and customize. Its robust security and encryption ensure that users’ personal data remains safe, making OZ an integral part of society. So much so, that even critical tasks, like controlling an unmanned asteroid explorer named Arawashi, are entrusted to it.

Enter Kenji Koiso, a 17-year-old math prodigy and part-time OZ moderator. When his crush, Natsuki Shinohara, invites him on a summer trip, he’s thrilled. However, he soon discovers that he’s expected to pose as her fiancé during the visit. As they arrive at Natsuki’s family estate, which is bustling with preparations for her great-grandmother’s 90th birthday, Kenji receives a mysterious coded message on his cell phone. Challenged by an unknown sender to solve it, Kenji cracks the code. But he’s unaware that by doing so, he’s just put the entire Earth in grave danger.

Ah, Netflix! A name that’s become synonymous with streaming and binge-watching. Most of us are already familiar with this global streaming giant. If you’re looking to watch Summer Wars on Netflix, there’s a catch. The anime is available, but only in Taiwan. So, if you’re not in Taiwan, you might need to use a VPN to access it. Remember, always use VPNs responsibly and be aware of the terms of service.

How to Watch Summer Wars on Netflix Anywhere in the World

This method works on both desktop PCs and mobile phones or tablets.

    1. Purchase (or start a free trial) of a VPN. I can confirm that Surfshark works for this purpose.
    2. In the settings, choose Taiwan as your location.
    3. Fire up the VPN and wait for it to do its magic.
    4. Once you’re connected, navigate to Netflix (browser or app).
    5. Search “Summer Wars” in the Netflix search bar and you should see the anime pop up.

Enjoy! Please note that if your Netflix library doesn’t update to reflect the country you selected in your VPN, you may have to clear the Netflix cache first and try again.

To do this on mobile, go to settings -> apps -> Netflix -> clear cache. To do this on PC, you have to clear the cache in your web browser.

I’ve had no trouble using this method and I still use Surfshark to watch anime from various Netflix country libraries daily.
