Book Information

From the closet to the world: the debut nonfiction novel depicting the journey of singer Ado and the inner truth of the "self" deep within her heart.

Based on Ado's own life story, this book was written by bestselling author Narumi Komatsu after three years of in-depth interviews. It thoroughly chronicles Ado's early childhood, her experience as a school refuser, her transformative journey into becoming a singer, her meeting with Chitokyo Chiyoshi, CEO of her agency Cloud Nine, and her meteoric rise from the birth of "Ado" to a world tour.

A "vivarium" is a miniature garden that recreates the natural habitat of living creatures. This book reveals the story of the artist known for recording music inside her closet before her debut—what emotions she held and what she created within that miniature world. The story of a girl named "Ado" is unveiled in this book.

【Original Author Profile】 Ado

From April 2025, she successfully completed a world tour covering 33 cities—the largest-scale tour by a Japanese artist. In November, she completed her first dome tour in Osaka and Tokyo. In July 2026, she will hold a concert at Nissan Stadium.
