The quest for the ideal VPN can be challenging, as it’s crucial to differentiate between privacy and security. Privacy pertains to keeping your online actions confidential, while security defends you from harmful threats and cybercriminals.

Within this context, the best VPN for Japan excels by providing top-notch privacy and unmatched security, but identifying such a VPN requires careful consideration and testing.

ExpressVPN stands out as the premier choice, distinguished as the best secure VPN service in Japan. It combines exceptional privacy features with robust security measures, ensuring a safe and private online experience. For those seeking the ultimate in VPN protection, I encourage you to explore my top selections, where ExpressVPN is the most reliable and secure option.

Quick Overview – Best Secure VPN in Japan

Need the best secure VPN service? Here is a quick overview of the 5 safest VPN providers in Japan:

What Features Does the Best Secure VPN in Japan Have?

The best secure VPN in Japan has several features that ensure the confidentiality, integrity, and availability of the data transmitted over the network. Some of the essential features of the most secure VPNs are:

  • Security and privacy: A secure VPN should have DNS leak protection, preventing DNS requests from leaking outside the encrypted VPN tunnel, and strong encryption such as AES (Advanced Encryption Standard).
  • Multiple device support: The best secure VPN allows users to secure all their devices through simultaneous connections.
  • Bypassing geo-restriction: Governments and some websites use potent anti-VPN technology like Deep Packet Inspection (DPI). VPNs can circumvent these restrictions and conceal their overall use, giving users access to geo-blocked websites.
  • Kill Switch and secure protocols: A kill switch automatically disconnects the user’s device from the internet if the VPN connection drops, preventing potential data leakage. Some examples of secure VPN protocols are OpenVPN, WireGuard, and IPsec, along with a no-log policy.
  • Ad blockers: the best secure VPN has native ad blockers that prevent popups, resulting in smooth and undistracted browsing. They also have built-in tracker blocking that prevents websites from storing your data.

By incorporating these features, a secure VPN provides users a safe and private connection, ensuring their online activities remain anonymous and protected from prying eyes.

Why Do I Need a Secure VPN in Japan?

You need the best secure VPN in Japan to safeguard your online privacy and prevent ISPs from tracking and potentially throttling your internet usage. It plays a crucial role in protecting your private information from hackers, particularly when connected to public Wi-Fi networks, ensuring your online activities remain confidential and secure.

This protection is especially important on public Wi-Fi networks. Using the most secure VPN provider, you create a private tunnel between yourself and the VPN server, preventing hackers, ISPs, and the government from monitoring your online activities. This ensures your actions online cannot be traced back to you, providing complete anonymity and protection.

Here are some more reasons why you need a secure VPN:

  • Ease your fears about using public Wi-Fi networks: Public Wi-Fi networks in cafes, hotels, and airports are plagued with all things dangerous and prone to hacking. VPNs play a crucial role in safeguarding your online experience, helping you stay safe with a public Wi-Fi hotspot in Japan.
  • Prevent cyberattacks: Hackers require your IP address to launch cyberattacks like DDoS, Man-in-the-middle, and Cookie Theft. A VPN assigns you a new IP address each time you connect to a server, thereby concealing your actual IP address in Japan alongside your online identity in a fell swoop.
  • Unblock websites: A VPN lets you change your IP address in Japan. Thus, it also helps unblock websites like Netflix, BBC iPlayer, and other streaming sites outside of their service areas. You can also use a VPN to dodge government-imposed restrictions on certain websites like Facebook or VoIP services like Skype.
  • Protect your IoT network: While smart devices in your home like fridge TV, virtual assistants like Alexa, and automatic security systems are there to make your life easier, they can also be the cause of significant security breaches if hacked. However, by configuring a VPN on your router in Japan, you can safeguard all of these devices at once and ward off hackers even when you’re not at home.

Methodology – How Did I Choose the Best Secure and Encrypted VPNs in Japan?

VPNs protect your online activities and keep you anonymous while browsing. Therefore, it is important to look for certain factors when choosing the best secure VPN in Japan.

The above VPNs are verified on basic testing criteria as given below. You can also use these factors as a guide for choosing the best encryption VPN in Japan:

  • No-logs policy: I prioritized VPNs with a strict no-logs policy to ensure they don’t store any records of users’ online activities, eliminating the risk of sharing data with third parties like authorities or advertisers.
  • Strong encryption: I looked for VPNs offering strong encryption, specifically those utilizing the AES-256 standard, known for its balance of security, privacy, and performance, to make user data unreadable to outsiders.
  • Kill switch: I included the presence of a kill switch as a critical criterion, as it disconnects your device from the internet if the VPN connection fails, preventing IP address and data leaks.
  • RAM servers: I considered using RAM servers a plus, as they enhance a VPN’s trustworthiness by ensuring data is not stored long-term and is wiped clean upon server restarts or shutdowns.
  • Jurisdiction: The jurisdiction under which a VPN operates was also a key factor in my evaluation, favoring VPNs based in countries with strong privacy laws that don’t require data retention or sharing, thus offering greater protection to users.

Which VPN Protocol is the Most Secure in Japan?

The most secure VPN protocol in Japan is OpenVPN, followed closely by WireGuard. OpenVPN stands out because it uses AES 256-bit encryption, a standard used by leading organizations including NASA and the military, offering robust encryption and exceptional security.

Let’s look at some common VPN protocols and determine their security standard:

VPN Protocol Security Level
WireGuard Very high
OpenVPN Low to high (configurable)
PPTP Very low
IKEv2 High
L2TP Medium
  • 1. IKEv2 – Suitable option for Android and iOS devices: This protocol is technically more stable than an OpenVPN connection. It is usually called IKEv2/IPSec because it is never implemented without IPSec encryption. However, this protocol is only available over UDP.
  • OpenVPN – Highly recommended security protocol: This VPN protocol is highly recommended for use and is available with all of my listed VPNs. It is known to be the most encrypted VPN protocol for users.
  • WireGuard – Next-gen protocol with top-notch security and fast speed: Despite being in the development stage, WireGuard is regarded as the most secure VPN protocol – a better version of OpenVPN. Equipped with a relatively small number of line codes, WireGuard makes the auditing process much easier and more straightforward.

The protocol should be available in all the best-encrypted VPNs for Android in Japan and through these VPNs, as it is capable of switching mobile networks and Wi-Fi quite seamlessly.

How to Set Up a Secure and Best-Encrypted VPN to Gain Online Security in Japan?

Follow these five easy-to-follow tutorial steps to set up the best secure VPN and gain online security and privacy with just one click:

  1. Subscribe to the best secure VPN service. I highly recommend ExpressVPN for its highly advanced security features and best-in-class privacy standards.
  2. Download the best-encrypted VPN app and sign in with your credentials. ExpressVPN offers apps for Windows, iOS, macOS, and Android.
  3. Go to settings and enable any advanced security and privacy features you prefer. It’s best to keep the Kill switch and DNS/IP Leak protection turned on.
  4. Select a server in your preferred location and hit the connect button. Once connected, your IP address will be changed. For example, connecting to a US server will grant you an American IP address.
  5. With an altered virtual location, your traffic will now be encrypted and concealed from your ISP and other online snoopers. Remember to connect your VPN every time you browse the internet.

How to Test for IP Leaks in Japan?

Every request you make while linked to a VPN is examined on a VPN server after traveling through an encrypted tunnel. However, DNS breaches can occasionally occur, meaning your data is no longer encrypted, and anyone can view and monitor your online activities.

As a result, it is critical to verify if your VPN is leaking regularly in Japan. Here’s a quick guide on how to do that:

  • Determine your actual IP address. Before visiting, ensure you are not connected to any VPN server.
  • Check the IP location and name of your VPN server.
  • Go to the page for the DNS leak test after opening your browser.
  • Check to see if your actual IP address and region match the results. If so, your VPN is not operating correctly.
  • Select Extended Test to view your DNS state in its entirety.
  • Verify whether your VPN provider’s or your ISP’s servers are being presented. Your VPN leaks if the server is your ISP or any other one you don’t know.
  • Contact your provider’s support and describe the problem if your VPN is leaking.

How Do I Secure My VPN Connection in Japan?

Securing your VPN connection is essential to protect your online activities and data. Here’s how you can secure your connection using the best secure VPN in Japan:

  • Subscribe to a VPN anonymously. Use a fake email to join a VPN and pay with cryptocurrency or fictitious debit cards to remain anonymous. This lets you be totally anonymous because none of the user’s credentials or your traffic can be linked to you.
  • Switch on the most secure tunneling protocol. Verify that the VPN service company utilizes the most secure tunneling protocol. Most VPNs choose a protocol immediately by default, which may not always be the most secure option. In addition, some companies continue to use antiquated protocols. Since these are currently the most secure VPN protocols, double-check and manually pick OpenVPN or WireGuard.


  • Enable the kill switch: If the VPN connection drops, use the kill switch feature provided by your VPN client to automatically disconnect your device from the internet.


  • Activate the auto-connect and auto-start functions. By enabling your VPN client to run at every device startup and connect automatically once it finds an internet connection, you can stop worrying about being unencrypted. You won’t need to take any extra steps to connect directly to a VPN server every time, which will save you time and clicks.
  • Update your VPN client regularly: To protect against vulnerabilities, keep your VPN client up-to-date with the latest security patches and updates.
  • Check for DNS leaks: Use a DNS leak test tool to ensure your VPN is not leaking your DNS requests outside the encrypted tunnel. Disable IPv6 to prevent any potential IP leaks that may occur if the VPN does not fully support IPv6.
  • Enable two-factor authentication (2FA): Use 2FA to add an extra layer of security to your VPN account.
  • Use your provider’s DNS services. At all times, use the DNS and servers provided by your VPN service. This will ensure that none of your web requests go through servers owned by unaffiliated parties who might want to monitor the URLs you frequent.

Following these tips, you can secure your VPN connection and protect your online privacy and security.
