During his Endlicheri-Endlicheri era, Domoto released three singles which all topped the weekly charts and made him the second male soloist after Masahiko Kondo to have achieved five consecutive number one singles.

On June 28, 2017, it was revealed that Domoto would be hospitalized for one week after experiencing sudden deafness, otherwise known as sudden sensorineural hearing loss.

In the video for the album's lead track "4 10 cake (Hot Cake)" Domoto is seen singing and dancing with various different dancers including Japanese Choreographer Riehata.^[21]

On February 22, 2024, Domoto announced via the fan club site that he would be leaving the agency on March 31.^[22][23] Days later, on his radio program "Domoto Tsuyoshi to Fashion and Music Book", he announced to the public his decision.^[24] One of the reasons for seeking his independence was his health, with priority for his hearing. According to Domoto, the doctor in charge said, "I think there is a need to change the environment significantly".^[25] He has been talking about his condition on the program, receiving messages from listeners who are battling illness themselves. That particular day, he received a message from a fan in his 80s, who was left paralyzed by a cerebral hemorrhage, and a man in his 40s, sentenced to six months to live. While addressing the listeners fighting illnesses, he was also telling himself, "I will never give up until the very end". Through such heart-to-heart exchanges, Tsuyoshi Domoto must have become more convinced that he only has one life, and that he must take care of himself. Tsuyoshi Domoto (the man) has not given up on Tsuyoshi Domoto (the artist).^[23] He also announced it in his Instagram, after deleting all his previous posts.^[26] "Regarding my personal activities, I have decided to terminate my contract with my agency on March 31, 2024 at the time of renewal and move on to a new field of life" "I felt that I needed to make a big change in my environment in order to continue my life as an artist", is part of the message he shared there.^[27] Regarding the activities of Kinki Kids and his relationship with Koichi, he said on the program "Kinki Kids donnamonya" that they had been talking about the ways to continue working together, not considering disbanding as a solution. Of course there was concern about the fans, and he stated it. "There will be new forms between us and our fans. However, the time we create (together) will have to change in order to continue. I think that's a very positive thing, and I don't think it's a problem if something changes. I think there's a future that we can walk towards because we're all part of it", he said, hopeful that the change will also reach the fans's future selves.^[28] Koichi Domoto had also shared his feelings about his partner's decision on the 22, saying "We will continue to deliver on our activities. Until now, KinKi Kids has continued activities while taking Tsuyoshi's health into consideration. There were some wonderful works and moving performances that were created because of these hardships. With Tsuyoshi's decision to continue his individual activities in a new field, expectations are high that the resolution of "what we want to express as KinKi Kids" will become clearer."^[23]

On January 11, 2024, Domoto and Momoiro Clover Z member Kanako Momota announced their marriage.^[29][30]
