Hello @Yasuichiro Tada ,
I understand that you would like to use bastion as Japanese (SJIS) on Linux.
Azure Bastion currently supports the listed keyboard layouts inside a VM as described in the below article:

I discussed your requirement with the Azure Bastion Product Group team and they mentioned that Azure Bastion do not currently support Shift JIS. However, they can add this to their backlog as a feature request for the future. So, I have created an internal feature request for same.
I would also request you to leave your feedback in the below forum requesting this feature. All the feedback you share in these forums will be monitored and reviewed by the Microsoft engineering teams responsible for building Azure.
