New-PnPSite does not create the pages in the proper language

[ComputerHabit2]

I'm using the following command:
New-PnPSite -Type TeamSite -Owners $owners -Title "$($alias)" -Alias "$($alias)" -SiteAlias "$($alias)" -Description "$($alias)" -TimeZone UTCPLUS0900_OSAKA_SAPPORO_TOKYO -Lcid 1041 -PreferredDataLocation JPN

The site created shows the LCID is 1041 however the HTML pages are all in English.

When creating a site in the admin console it creates the pages properly.

Japanese on Default page.

I saw a reference to a known bug but it's several years old.

pnp/PnP-PowerShell#2618

It seems this issue is still there. Is there a way around it?
