Kawasaki Yasushi believes that from birth, we interact with people who share similar characteristics with us, such as parents, siblings, or relatives. As a result, we develop a subconscious recognition of familiar faces, perceiving them as similar to our own. He notes that it is common for people to think that pets resemble their owners or that couples grow to look alike over time, seeing this as a natural psychological phenomenon.

In his artworks, Kawasaki often creates portraits that carry his own features. He sees this as a subconscious process rather than a deliberate attempt to imitate a specific subject, and thus refers to these works as “self-portraits.” Regardless of whether the subject appears male or female, he believes these works reflect his own projection and are not bound by gender.

After getting married, Kawasaki began to observe the subtle dynamics of a two-person relationship. These observations inspired his creations, exploring the processes of mutual acceptance and influence within the smallest social unit of a couple.
