In her published book, "The Silver Bonbonniere (French word: A small, ornate box or dish for candy)," Setsuko wrote on this Peach Festival event, 'The Empress Teimei had four children who are all Imperial princes (boys), so she seems to look forward to the Peach Festival with pleasure.'
勢津子は自身の著書『銀のボンボニエール』において、そのことを「お子様4人全員が親王様（男子）であったので、毎年お楽しみにされているのでしょう」と語っている。
