How can I extract a Japanese-encoded .7z archive on Linux Mint?

You can also open the archive with a graphical utility such as Ark, File Roller, or Xarchiver. These tools support 7z files and may integrate with the file manager, so you won’t need to use the terminal.

Use the 7-Zip command-line tool rather than `unzip`, since `unzip` only handles ZIP archives. On Linux Mint, install it with `sudo apt update && sudo apt install p7zip-full p7zip-rar`, then extract the archive with `7z x archive_name.7z`. 7z archives generally handle filenames differently from older ZIP archives, so the Japanese names may work without any extra locale option.

If the archive extracts but the filenames still appear garbled, try fixing their encoding afterward with `convmv`. First extract the files with `7z`, then use `convmv` to convert the filenames to the encoding your system expects.
