A Comprehensive Guide to Surfshark: From Sign-Up to Usage | How to Use the Internet Safely with a VPN

春雨

A VPN is a technology that creates a virtual tunnel over the internet and encrypts your data to make browsing safer. It’s now essential when connecting to public Wi-Fi on the go, such as on a smartphone.

In this article, I’ll walk you through everything from signing up for Surfshark—one of the paid VPN providers—to how to use it, complete with illustrations.

Surfshark Features

  • Japanese language support is expanding
  • Unlimited simultaneous VPN connections (the whole family can use it)
  • All apps support Japanese
  • Minimal impact on connection speeds
  • Money-back guarantee within the first 30 days
  • Guaranteed no-logs policy (verified through independent audits)
  • 1-year and 2-year plans are more affordable than other major VPN providers

About Surfshark

Surfshark is a service provided by Surfshark B.V., a company currently based in the Netherlands. It is a relatively new company founded in 2018. It merged with Nord Security in 2022 and operates as a standalone business. The company primarily focuses on internet security services, including VPNs and antivirus software.

As of December 3, 2022, it has over 3,200 servers in 100 countries.

Unlike ExpressVPN and NordVPN, Surfshark is notable for having no limit on the number of devices you can connect. Additionally, its 2-year and 1-year plans are significantly cheaper than those of ExpressVPN and NordVPN. Since there is no device limit, the whole family can use it.

Like other providers, it offers a 30-day money-back guarantee, so I recommend giving it a try.

How to Sign Up for Surfshark

Go to the Surfshark website.

[SurfShark] ⇐Click here
Surfsharkホームページ

Click the "Get the VPN Deal" button.

サブスクリプションの選択

Select a plan. In this example, we’ll sign up for the 1-month plan.

バンドル追加するかどうか

You can add features like data privacy protection and antivirus software. However, if you just want to use the basic VPN functions, these aren’t necessary.

Click the “Continue without bundle” button.

メールアドレス登録と支払い方法

Enter an email address for your account and select a payment method. I paid via PayPal.

確認ページ

Accept the cookies and click the "NEXT" button.

アカウント情報入力ページ

Enter your name and address, then proceed to the next step.

確認・購入ページ

Review your subscription details and click "BUY NOW."

購入完了

Since payment is complete, click "Continue to your Surfshark account."

パスワードの登録

You will be taken to the screen to set your account password. Set a strong password that is at least 8 characters long and combines lowercase and uppercase letters, numbers, and symbols.

Points

To use the internet more securely with a VPN, set a strong password for your VPN account by combining uppercase and lowercase letters, numbers, and symbols.

優待プラン

Once your account is created, you’ll be offered a 12-month discount plan, but let’s skip that for now.

デバイス設定

You’ll be taken to a screen to install Surfshark on your computer and mobile devices. Click “Mobile” to display a QR code.

First, select "Computer."

How to Use Surfshark

Installing the Surfshark App

PCアプリダウンロード

A button to download the desktop application will appear.

Download it.

Open the downloaded file and install it.

PCアプリインストール
PCアプリインストール中
インストール完了とログイン

Once the installation is complete, you will be taken to the login screen. Click the "Log in with credentials" button, then enter the email address and password you set up earlier to log in.

アプリのログイン画面
ログイン後

Once logged in, you will be taken to the settings screen. If you want to connect automatically, enable "Auto-connect."

手動でVPNに接続

This is the screen for manually connecting to the VPN. Enter the country you want to connect to in the search bar, or click "Fastest Location" to connect to the fastest server.

Even if you type "Japan" in kanji in the search bar, a list of Japanese servers will appear, so you can select a server and connect. For the U.S., you need to enter the name in English (e.g., "us") rather than katakana.

日本国内サーバー一覧

Key Points

You can select a server from the list of servers by country and connect to it.

If you check your IP address using a browser tool, you'll see that it has changed from your original IP address.

確認くんIPアドレス確認

Please note that clicking the link below will immediately display information such as your IP address.

Check-kun

I tested the connection speed.

When connecting to a Japanese server via the app

PCアプリで日本サーバーの速度

When connecting to a US server via the app

PCアプリでアメリカサーバーの速度

In my home environment, even without a VPN, my maximum speeds are around 50 Mbps download and 20 Mbps upload, so my connection speed hardly dropped when connecting to a Japanese server.

There was a slight drop in speed when connecting to a US server, but it wasn’t enough to cause any issues with streaming videos or similar activities.

Since connection speeds drop with any VPN, I think this is within an acceptable range.

Key Points

While speed drops are common with any VPN, Surfshark delivers sufficient speeds.

Click the gear icon on the left to access various settings.

VPN設定

In the VPN settings, you can choose to automatically launch the app at startup and automatically connect. For the protocol, you can select OpenVPN, a reliable connection method, or WireGuard, which offers faster connections. Normally, the default settings should be fine. If you feel the connection is slow, switch to WireGuard. The Kill Switch is a feature that automatically disconnects your internet connection when you are not connected to the VPN.

In Bypasser, you can select applications and websites that you want to bypass the VPN.

Bypasser アプリケーション

When you turn on "Bypass VPN," a list of applications will appear; by checking the boxes next to the applications you want, you can allow them to connect to the internet without going through the VPN.

If you turn on "Bypass VPN" for websites, you can bypass the VPN by adding the URLs or IP addresses of websites you don’t want to route through the VPN.

Bypasser Webサイト

Key Points

You can configure applications and websites that bypass the VPN connection using Bypasser.

Like NordVPN, the desktop app connects your entire system to the VPN.

Installing the browser extension

Select "Apps & Extensions" from the Home menu on the left side of the Surfshark website to install browser extensions and other tools. Please install the extension for your browser.

ブラウザ拡張機能のインストール

Clicking the browser extension icon will bring up a login dialog. Enter your account email address and password to log in.

ブラウザ拡張機能初期画面

Once logged in, you will be taken to the dashboard.

ブラウザ拡張機能ダッシュボード

From here, you can connect using "Quick Connect."

Hover your mouse over the left side to display the menu.

ブラウザ拡張機能手動接続画面

In the VPN menu, just like in the app, you can select a country to connect to, or enter "Japan" in the search bar to view a list of servers and choose one.

ブラウザ拡張機能国内サーバー一覧

Once connected, the screen will look like the image below.

ブラウザ拡張機能サーバー一覧から接続

Click the gear icon in the lower-left corner to open the settings screen.

ブラウザ拡張機能設定

In "VPN Settings," you can configure connection settings for Quick Connect, as well as options such as whether to connect automatically when you launch your browser.

ブラウザ拡張機能VPN設定

In "CleanWeb Settings," you can configure the ad blocker, cookie pop-up blocker, data breach alerts, and malware alerts. I think leaving most of these at their default settings is fine.

ブラウザ拡張機能CleanWeb設定

The "Bypass List" displays a list of websites to exclude from the VPN connection.

ブラウザ拡張機能バイパス設定

When you visit a website you want to exclude, click the "Add New" button to enter its URL, configure the details, and exclude that site from the VPN.

I tested the connection speed.

When connecting to a Japanese server via the browser extension

ブラウザ拡張機能日本サーバーの速度

When connecting to a US server via the browser extension

ブラウザ拡張機能アメリカサーバーの速度

When connecting to a server in Japan, there was almost no noticeable drop in speed. When connecting to a server in the U.S., if I connected to a server with low traffic, I achieved speeds fast enough for activities like watching videos. However, on busy servers, there were times when the speed dropped significantly. As with other VPN providers, server performance can vary. Be sure to choose a server with low traffic.

As with NordVPN, the browser extension only establishes a VPN connection within the browser.

If you’re using both the app and the browser extension simultaneously, you may experience significant connection issues.

Important Note

If you are using both a VPN connection via a PC app and a VPN connection via a browser extension, you may experience connection issues.

Install on Your Mobile Device

On the Surfshark login page, go to "Home" > "Apps & Extensions" or "VPN" > "Setup Guide" to find the QR code for installing the app on your mobile device. Scan this code with your mobile device to install the app.

If you signed up on a mobile device, use the URL below

https://my.surfshark.com/auth/login

モバイルデバイスログイン画面

.

モバイルデバイスログイン後

Tap "Apps & Extensions" and download and install the app from the store.

モバイルデバイスアプリストア

Once the app launches, tap the "Already a user? Log in" button to log in.

モバイルデバイスアプリログイン画面

Once logged in, start by using Quick Connect.

モバイルデバイスクイックコネクト

You’ll see a message saying “Surfshark is requesting to add a VPN configuration,” so tap “Allow.”

モバイルデバイスVPN構成の追加許可画面

You should now be able to connect.

モバイルデバイスVPN接続成功

There is a menu at the bottom where you can select the country and server you want to connect to under "Location."

Tap the gear icon on the far right to access various settings, such as Auto-Connect, CleanWeb, and the Kill Switch.

I ran a speed test.

When connected to a server in Japan

モバイルデバイス日本サーバーの速度

When connected to a server in the US

モバイルデバイスアメリカサーバーの速度

Both showed satisfactory connection speeds.

Key Points

VPN connections on mobile devices are also simple and fast. You can configure the settings just like on a computer.

Summary

Surfshark is more affordable than other major VPN providers on its 1-year and 2-year plans. Additionally, the account page, app, and browser extensions are available in Japanese, making it easy for Japanese users to navigate. It offers all the basic features you’d expect from a VPN, and connection speeds are fast enough for streaming videos. Unlike other major VPN providers, there’s no limit on the number of devices you can connect, so you can use it on as many devices as you like without worrying.

That concludes our guide on everything from signing up for Surfshark to how to use it.
