Nintendo Switch Online has over 15 million subscribers, will continue to enhance the service’s appeal

This information comes from Nintendo president Shuntaro Furukawa…

One more point to mention is the more than 15 million accounts worldwide with a paid membership to Nintendo Switch Online, and those sales occupy a certain presence within our digital sales. But while new members continue to join, there are also those who do not renew their memberships. We will continue to enhance the appeal of the service to bring more features and more fun to Nintendo Switch.
