[New Content] Announcement of the start of the Sustainable Challenge
Thank you for always using our community portal site. We have now launched a new content called "Sustainable Challenge."
First, let's try the "Healthcare" theme!
If you clear each chapter in the theme and collect all the gem-colored berries that are available, you can exchange them for a 100 yen Amazon gift certificate!
What is "Sustainable Challenge"?
It's a game-like content where you read articles on sustainability themes such as eco-friendliness and healthcare, and deepen your understanding by taking quizzes.
As you progress through the Sustainable Challenge, you'll receive Sustaina-berries and gem-colored berries, which can be exchanged for special benefits and prizes!
In the future, quizzes related to eco-friendliness and peace of mind for everyone in the facility will be updated on this portal at any time.
