Ryuichi Sakamoto shocked the world with his techno music as a member of YMO and continued to capture the hearts of many with his unique music. In his diary in his final years, he wrote about the anguish of his life fighting the disease, thinking, "It's a death sentence" and "Should I choose euthanasia?" and "Music may be the only way to stay sane," and "Music to leave behind, music to leave behind." His true feelings were engraved, including words that made him think deeply—his interaction with unknown members of YMO and the unreleased song that ended up touching his heart.
