In addition to her professional life, Ryoko Iori is also known for her personal life and philanthropic efforts. In 2003, she married Japanese actor and musician, Gackt, with whom she has a son. The couple divorced in 2009, but Ryoko Iori has continued to be involved in various charitable initiatives, including supporting organizations that promote education and healthcare for children.
Her interactions with food, particularly her obsession with taiyaki (fish-shaped pancakes), are not mere quirks. For Iori, food is a substitute for emotional nourishment. She hoards it, shares it aggressively, and talks about it constantly because it is one of the few uncomplicated joys she allows herself.
