About a year or two ago, someone recommended a phenomenal dystopian novel about people who don’t have kids and are sent to live in a luxury facility where they serve a particular function for their remaining lives. It was by a Japanese author, I believe a woman. Does anyone know the name of the book and/or the author?

Bonus question: Any other Japanese sci-fi/dystopian/magical realism book recommendations?

I'd love to hear everyone's thoughts who watched through the basho.

I don't have all my thoughts together yet but wanted to post this after watching the last day of the basho to get the ball rolling on any discussion.
