In this study, sign language expressions were collected from two cooperating deaf people—one from the 30 year-old group and the other from the 70 year-old group from each prefecture, and the Japanese Sign Language (JSL) Map was created on the basis of the data collected. Please understand the research objectives and take note in advance that the sign language expressions in the JSL map (prototype) are not necessarily considered to be common expressions in each prefecture.
