I had lived a life full of music. However, it has changed completely after it was discovered that the second daughter had hearing loss. My second daughter went to a deaf school and had the opportunity to meet sign language. She wears cochlear implants on both ears and lives a life that utilizes hearing, but she communicates in sign language during the time when she is not wearing it. In this paper, I will consider the scenes of performing two "sign language songs" that the author knows from the perspective of the author who has contact with music and sign language.

“Signed sogns” which will be discussed in this general remarks, is the act of producing musical sounds by voice and at the same time singing with sign language attached. Sign language songs are attracting attention as a new genre in music, and are increasingly being sung by school children and used by solo singer and groups of singers. I will focus on what I felt during the series of signed songs commotion that occurred on Twitter around February 2021. Key words: Sign language songs, NMM, CL, Psychological suppression, Language of Law

This paper draws attention to the current situation, "syuwauta" (sign language songs), which are created mainly by hearing sign language users on social media platforms. Most of them are not members of the Deaf community, and therefore they do not own that language. This a known as a Linguistic Hijack. In this paper, I exhibit why the use of #syuwauta is problematic in Japan. The original meaning of the word syuwauta has been identified as a semantic drift. The term syuwauta was exploited by hearing sign language users for their benefit. With a social justice and a ground-based framework, this paper explains the history of the word syuwauta and how the original meaning has been corrupted through the majority's two patterned behaviors; willful blindness and the misuse of the word.
