While the film features a travel and beauty theme, it's not a traditional narrative film with a cast of actors and actresses. Instead, it documents the journey of a group of women who are traveling around Japan and visiting different hot springs (onsen). The film is essentially a travelogue with the focus on the scenic locations and the experiences of the women.
Therefore, there is no established cast of actors and actresses in the film. The women featured in the film are likely non-professional actors, but their names and specific identities are not publicly available information.
