This error shows up when I do the following:

  1. DL and paste this extension under DIR>vendor>magento-japan folder m2-jplocalize

  2. Run the following command:

    composer config repositories.veriteworksartifacts artifact \vendor\magento-japan

    composer require magento-japan/m2-jplocalize

    php bin/magento setup:upgrade

  3. Then this error shows up:

    Module 'Veriteworks_Region' from '\vendor\magento-japan\m2-jplocalize/region' has been already defined in '/vendor/veriteworks/m2-region'.

Where did I go wrong? Is this the correct way to install this extension?

No, it's not. Skip the first step, composer already downloads the extension in step 2
