The new production casts her as a private tutor. The opening places her in glasses, a green V-neck knit top and gray skirt before changing the styling beneath it. Another sequence moves from a drive with the student to the seat-belt image used on the package.
“I never thought I would use a seat belt to cover my breasts in my life,” Koyama said. “It feels like something out of the ordinary inside everyday life. It made for a very memorable cover, so I like it.”
A public-bath scene was another point she singled out, saying that its minimal towel styling reflected both her experience and how she now approaches the work. She also said viewers had welcomed the return after the long break.
Work beyond the DVD
Koyama continues to accompany day-trip bus tours, guiding customers at destinations, and sometimes works on school excursions. She holds a Domestic Itinerary Management Supervisor qualification for that work.
“I mainly accompany day-trip bus tours,” she said. “Sometimes I also go with students on field trips and school trips. I take in their energy, and I really enjoy the work.”
Koyama was born September 15, 1994, in Ibaraki Prefecture and is 158 cm tall. She said she planned to continue appearing at pool photo sessions in September.
