Tutorial: Connection

As of 2018, users are no longer required to have a Japanese VPN to play kancolle (Some countries might be blocked though not US and EU)

However, if you are one of those that required a Japanese VPN to play; thus, this page guides new users on bypassing this restriction.

Option 1: VPN Gate or other VPN

Windows

1. Head over to VPN Gate, an "Academic Experiment Project" by the University of Tsukuba.
2. Download, install and run the client.
3. Select a Japanese server in "VPN Gate Public VPN Relay Servers".

Mac / Linux

• There is L2TP VPN interface that has been pre-installed in your kernel system. You can directly set it up without needing to download any clients or using similar software to let you execute Windows-only clients. However, in case your network is blocking the usage of L2TP, you will still need to download VPN clients to let you use VPN with different protocols.

1. Open Network Preferences.
2. Click add connection, then select VPN (L2TP)
3. Go to VPN Gate, and find a Japanese server that supports either "L2TP/IPsec" connections.
4. Copy the server's address (eg. vg2036075803.opengw.net).
5. Paste the address to the "Server Address", and type vpn as the "Account Name".
6. Click "Authentication Setting", then type vpn for both available textboxes. You do not need to change anything else.
7. Click "Advanced", and tick Send all traffic over VPN Connection.
8. Click OK, then Apply, and test the connection using the "Connect" button.
9. If the VPN fails, try to add the IP address to the "Server Address" instead of the full server name.
   If this one fails too, you can try turning off your whole internet connection for 1-2 minutes before trying to connect to the VPN again. This issue sometimes occurs when you suddenly disconnect from the VPN due to a poor connection or incomplete request.

Creating an L2TP or STTP VPN connection (Windows 8)

This method works for Windows 7 as well, but the wording of the settings might be different.

1. Go to VPN Gate, and find a Japanese server that supports either "L2TP/IPsec" or "MS-STTP" connections.
2. Copy the server's address (eg. vg2036075803.opengw.net). For STTP-supporting servers, copy the address plus the port number, shown in the MS-STTP column.
3. "Set up a new connection or network" in Network and Sharing Center.
4. "Connect to a workplace"
5. "Use my Internet connection (VPN)"
6. Paste the address (plus the port, for STTP), name the VPN connection as you wish and click on "Create".
7. (L2TP users skip to step 8 for now) The VPN connection should appear in "Network Connections" (or the sidebar that appears when you click on the network icon in the taskbar). When asked for Username and Password, input "vpn" for both.
8. For L2TP users, you must find the network connection that was just created, and go to its "Properties" by right clicking on the just-created connection in "Network Connections". Go to the "Security" tab, select L2TP/IPsec as the "Type of VPN" and then click on "Advanced settings". Select "Use preshared key for authentication" and then input "vpn". Apply the settings. Connect to the VPN as per step 7.

This method is for users of Mac and UNIX-based systems:

1. Open Network Preferences.
2. Click add connection, then select VPN (L2TP)
3. Go to VPN Gate, and find a Japanese server that supports either "L2TP/IPsec" connections.
4. Copy the server's address (eg. vg2036075803.opengw.net). 
5. Paste the address to the "Server Address", and type vpn as the "Account Name".
6. Click "Authentication Setting", then type vpn for both available textboxes. You do not need to change anything else.
7. Click "Advanced", and tick Send all traffic over VPN Connection.
8. Click OK, then Apply, and test the connection using the "Connect" button.
9. If the VPN fails, try to add the IP address to the "Server Address" instead of the full server name.
   If this one fails too, you can try turning off your whole internet connection for 1-2 minutes before trying to connect to the VPN again. This issue sometimes occurs when you suddenly disconnect from the VPN due to a poor connection or incomplete request.

Mobile Gameplay

The only officially supported ways to play are via the Kancolle Android Version or through a desktop browser client (e.g. Chrome, Firefox, etc.). Any other implementations of flash, such as mobile flash imitations/emulations or even mobile versions of chrome are not supported. These are not recommend as your data may not be secure, and may also not send data to the KC servers in the same way as an officially supported method would, putting you at risk of getting banned.
