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

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.

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.

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.
