Describe the problem

I get the following error when I set japanese to windows>nsis>language in tauri.conf.json

  "tauri": {
     ....
      "windows": {
        "nsis": {
          "languages": ["japanese"]
        }
      }

build error

       Error failed to bundle project: Language japanese not implemented. If it is a valid language listed on <https://github.com/kichik/nsis/tree/9465c08046f00ccb6eda985abbdbf52c275c6c4d/Contrib/Language%20files>, please open a Tauri feature request

Japanese was added into the cli in v1.3.1: #6940 but it's currently broken with a fix being here: #7086 - thanks for the request :)

@FabianLars
Thanks for the comment.
Is there a way to apply the #7086 modifications on local?

[FabianLars]

You'll have to use the CLI from git, here's a small guide showing you how: https://tauri.app/v1/guides/faq#how-can-i-use-unpublished-tauri-changes
