Wait, the user mentioned "useful feature," so it should add real value. Maybe a language translation feature on the website, since some fans are non-Japanese. Subtitles for videos, or translated stories. Also, a way to submit fan mail that could be selected for future content. Or a digital scrapbook where fans can create their own pages using the photobook's content.
Another thought: interactive elements in the physical book. Like pages that, when scanned, show a video of the photo being taken. Or a behind-the-scenes look at the photoshoot mentioned in the link.

Also, a calendar where each month's page in the photobook corresponds to specific memories or events in her career. Or a fan forum where people can discuss the photobook and share their own insights.
Hmm. I think the most impactful would be an augmented reality feature that ties physical photos to digital content, plus a companion app with interactive elements. That way, fans can use both the physical and digital aspects of the photobook. Including links to her music, interviews, and maybe even a mini fan wiki with information on each photo's context.
