Sidenote: you will still need one, but by the end of the guide you should only need to deal with this process once per year, assuming nothing changes.
Note
This guide only covers VPN setup, creating DMM account & installing Game Player is considered out of scope (this is long enough as is).
Use Nyatsu's DMM guide for guidance on getting set up, or check #jp-questions pins in maincord.
Warning
This guide was rewritten in August 2025 to no longer use TunnlTo. If you need the old version, it can still be accessed here.
