Seem like you need VPN, JP VPN to be specific

You could use SoftEther vpn

use a VPN in the Japan region, the VPN I use is VPN Gate

Maybe the VPN server you chose started with 219.xxx.xxx.xxx, recommend checking step #3 of this VPNGate guide to test if the server is blocked.

Have you success get in with your current vpn setting before ?

Well, if that was why, thank you, I can play it now.
