Osaka Castle Triathlon Course Highlight


We will swim in the eastern outer moat of Osaka Castle. This location served as a rugby field and sports ground in the post-war period. The moat was restored to its current form during the construction from 1994 to 1997, coinciding with the completion of the ‘Heisei Era Grand Renovation’ of the main keep in March 1997. The triathlon swimming competition held in this moat has garnered significant attention from various media outlets. This year, it’s your turn to swim!


Swiftly sprinting from the verdant forest of Osaka Castle Park to the towering skyscrapers of Osaka Business Park. Exiting the water and greenery of Osaka Castle Park, heading north along Tamatsukuri-suji towards the high-rise buildings of the International Information City, OBP, where culture and information coexist. The course loops back in front of the ytv Kyobashi Building.
