Haruka Kitaguchi gained international recognition by winning the javelin world title in 2023, followed by Olympic success a year later. She describes her ultimate performance as her final throw at the 2023 World Championships, underscoring its importance in her career.
Kitaguchi has expressed admiration for swimmer Michael Phelps as her ultimate athlete and cites the competition between Karsten Warholm and Mondo Duplantis over 100 meters as an ultimate clash she finds compelling. Beyond athletics, she recalls the women's basketball quarter-final between Japan and Belgium at the Tokyo Olympics in 2021 as particularly memorable.
Among her personal favorites, Kitaguchi names Sanma (Pacific saury) sushi as her ultimate meal and enjoys spending time drinking with family and friends or alone as her ideal night out or in. She also values sleep and enjoying delicious food on her day off.
Her pre-competition music choice is "Mr.Simple" by Super Junior, and she prefers visiting new countries to experience their history and culture as her favorite type of holiday. Kitaguchi also notes a unique hidden talent: falling asleep immediately upon entering a vehicle.
