シングル第16弾。「AI化された未来に向き合う「心」の世界。心ある日本の「おもてなし」を探す旅。"さあ、ようこそ。いらっしゃい。" YYオリジナルソング。
The 16th single of YY (Koto: ASUKA & Beat: Wocasi). "YOUKOSO" means "Welcome". In Japan, there is a custom of giving warm-hearted hospitality as a way of expressing a feeling of welcome=OMOTENASHI. However, the "warm-hearted hospitality" is being lost. This song is a song that has the desire to cherish such "heart" forever.
