Would it be possible to receive the photos taken during the interview via LINE or something similar?

Maezawa here with an answer. We used to provide them, but some people were using the photos elsewhere. With the large number of interviews, there was also the issue of the time and effort involved in handing them over, so we no longer provide them. That said, policies vary by branch, so why not ask the staff member in charge at your interview? Some branches may be willing to accommodate you—for example, by providing one photo or perhaps five or six. Incidentally, when showing the photos just taken on the camera’s rear LCD screen, there have also been women who took a photo of it with their own smartphone—after asking, “May I take a picture of this?” first.
