First edition, 2002. The cover shows some wear, but the book is generally in good condition. This is Shiina's 4th and final photobook, taken when she was 24 years old. Shiina first came to public attention as a reporter on "Tonight 2." This program employed gravure idols as reporters, and many of them released photobooks. There was a tendency to cast those with large breasts, and among them, Shiina, with her 93F bust (various sources differ), stood out significantly. Her previous photobooks also featured her chest prominently, but this final work is less focused on that aspect, and instead, it seems to aim at capturing the sensuality Shiina could express. As the title suggests, the theme is a secluded hot spring trip. This is undoubtedly Shiina's best work.
