このガイドを信頼する理由

I have run TunnelBear VPN for over two years on a Windows PC, a Mac, and an Android phone.

Every screen below comes from my own account, not from vendor marketing.

TunnelBear is one of the easiest VPN apps you can install today.

Most people connect once and never touch the rest of the software.

This guide shows you how to use every feature that matters.

スクリーンショットとプロのアドバイスを交えながら、手順を一つずつ解説します。

TunnelBearチュートリアル

This TunnelBear tutorial walks you through setup, then each feature, then the tips that turn you into a power user.

TunnelBear の利用開始

Do this one-time setup before you touch any feature.

約3分かかります。

まずはこちらの簡単な概要をご覧ください。

それでは、各ステップを順を追って見ていきましょう。

ステップ1：アカウントを作成する

Go to the TunnelBear website and click Get TunnelBear.

Creating the account takes one email and a password you do not reuse anywhere else.

✓ チェックポイント: You must verify your email address to activate the account.

ステップ2：アプリをダウンロードする

Downloading takes under a minute on most connections.

There is a desktop build for Windows and Mac, plus mobile apps for iOS and Android.

ダッシュボードの画面は以下のようになります。

✓ チェックポイント: You should see a map with a country list on the left.

ステップ3：初回接続

Log in, pick a country, and flip the switch to on.

The bear tunnels across the map, and your device is connected in a few seconds.

How to Use TunnelBear Private Connection

プライバシー lets you keep your internet service provider from logging the sites you visit.

以下に、その使用方法をステップごとに説明します。

Step 1: Open the App Settings

Click the gear icon in the top corner of the app.

Every privacy toggle in the software lives on this one screen.

Step 2: Turn On VigilantBear

VigilantBear is the kill switch that blocks traffic if the VPN connection drops.

これがその様子です。

✓ チェックポイント: VigilantBear shows a green toggle and stays on after a restart.

Step 3: Run a Leak Test

Connect, then open any DNS leak チェッカー ブラウザで。

Only the TunnelBear server should appear in the results.

How to Use TunnelBear VPN

高速パフォーマンス lets you hold onto usable internet speed while every packet stays encrypted.

以下に、その使用方法をステップごとに説明します。

Step 1: Test Your Baseline

Run a speed test with the VPN off and note the number.

This is the ceiling your connection can reach.

Step 2: Pick the Closest Server

Distance costs you more speed than encryption does.

これがその様子です。

✓ チェックポイント: The connected result lands close to your baseline internet speed.

Step 3: Retest and Compare

Run the same test again while connected.

Losing ten to twenty percent is normal for any VPN.

How to Use TunnelBear Encrypted Connection

接続を暗号化する lets you encrypt everything you send over public wi fi so nobody nearby can read it.

以下に、その使用方法をステップごとに説明します。

Step 1: Join the Network First

Connect to the cafe or airport wi fi before you open the app.

Accept the login page if the network shows one.

Step 2: Flip the Switch

Tap the toggle and wait for the tunnel to finish building.

これがその様子です。

✓ チェックポイント: The map shows a tunnel from your city to the server you chose.

Step 3: Confirm the New IP Address

Search for what is my IP and check the result.

It should show the country you picked, not your own.

How to Use TunnelBear Universal Browser

他の国で閲覧する lets you access sites and services that are only available in different countries.

以下に、その使用方法をステップごとに説明します。

Step 1: Open the Country List

Click the tunnel icon to see all 47 countries.

Type in the search field to jump straight to one.

Step 2: Choose Your Country

Pick South Korea for gaming, or the UK for local news.

これがその様子です。

✓ チェックポイント: The site loads in the language and currency of the country you picked.

Step 3: Reload the Site

Clear your cache, then reload the websites you want.

Accessing a site from a new country often needs a fresh session.

How to Use TunnelBear Strong encryption Tool

強力な暗号化 lets you lock down the account itself, not just the tunnel your data travels through.

以下に、その使用方法をステップごとに説明します。

Step 1: Check the Protocol

TunnelBear runs OpenVPN and IKEv2, both audited and secure.

The app picks the right one for your device automatically.

ステップ2：二段階認証を有効にする

Open the Security tab on the TunnelBear website or in app settings.

これがその様子です。

✓ チェックポイント: The Security tab shows 2FA enabled with a backup code saved.

Step 3: Review Your Devices

One subscription covers five devices connected at the same time.

Remove any device you no longer own.

How to Use The GhostBear Feature

ゴーストベア lets you hide the fact that you are using a VPN at all.

以下に、その使用方法をステップごとに説明します。

Step 1: Disconnect First

GhostBear cannot switch on mid-session.

Turn the toggle off before you change anything.

Step 2: Enable GhostBear in Settings

Find GhostBear under the same settings panel as VigilantBear.

これがその様子です。

✓ チェックポイント: The connection completes on a network that blocked you a minute ago.

Step 3: Reconnect and Test

Connect again and load a blocked site.

Expect slower speeds, because the disguise adds overhead.

ほとんどの人が見逃す隠れた機能

• Browser extensions: Lightweight builds for Chrome, Firefox, and Microsoft Edge that only cover your browser.
• 2要素認証: Sits in the Security tab and takes about a minute to set up.

TunnelBearでよくある間違いを避ける方法

Mistake #1: Leaving VigilantBear switched off

Mistake #2: Streaming on the free version

Mistake #3: Staying on a far server by default

TunnelBearのトラブルシューティング

Problem: A site keeps verifying you are human

原因： Shared VPN servers get flagged, so the site runs a security check before proceeding.

修理： Wait a few seconds while the box reads verifying, then verification successful, waiting for the site to respond.

If the challenge loops, note the Ray ID, switch servers, and try again.

Problem: A site asks you to update your browser

原因： An old build plus a VPN extension trips the compatibility check on some sites.

修理： Update your browser to view this site properly in Chrome, Firefox, or Microsoft Edge.

Disable other extensions first, since they cause the same warning more often than the VPN does.

Problem: Netflix blocks your connection

原因： Streaming services block known VPN server ranges, and TunnelBear is inconsistent here.

修理： Clear cookies, pick a different server in the same country, and reconnect.

📌 注記： If none of these fix your issue, open a support ticket by email, answered 24/7.
