JAPAN VERSION

STEP 1
Because CSO2 Japan uses the same registration process as CSO Japan, you could follow the registration tutorial here.

STEP 2
Make sure the game client along with the z01 and z02 files from the Download Page are downloaded to avoid any errors during or after installation!


STEP 3
This version is region-locked to Japan only, therefore players residing outside Japan are required to download a Virtual Private Network client to bypass it. Free ones are available such as SoftEther VPN that allow one to change the IP address.

STEP 4
Install the VPN, launch the VPN and change the IP address before re-accessing the site.
