1. make a directory where you want to install the Japanese man pages.

   sudo mkdir /opt/homebrew/var/cache/man/opt/ja_JP.UTF-8 ### optional

2. add the install dir to \$MANPATH.

export MANPATH="/opt/man:$MANPATH"

* .zshrc

MANPATH="/opt/man:$MANPATH"
dedup_path MANPATH "$MANPATH"
export MANPATH

1. export LANG=ja_JP.UTF-8 ### write into somewhere.
