I set up a Drupal development environment using Lando, referring to the following site.
https://www.acquia.com/jp/blog/how-to-use-lando-for-building-drupal-local-environment
For installing drush on it, the following was helpful.
https://docs.lando.dev/drupal/getting-started.html#quick-start
By running the following command, drush became available.
I hope this serves as a useful reference for others.
