SUsaki OWS (Open Water Swimming) 2025

Marine sports

Open water swimming is a long-distance swimming competition that takes place in natural waters such as the sea, rivers and lakes. The acronym for the name in English is abbreviated as OWS. Because it is susceptible to various external influences such as weather, tides, and living things, it is necessary not only to swim faster, but also to learn and experience to swim in nature, including crisis management.

Remarks: Continuing from last year's tournament, we will make full use of two drones and three ground cameras to deliver live images of powerful competition scenery from angles that you can not usually see on YouTube and on the venue monitor. In addition, by upgrading to display the ranking, time, etc. to the screen, it has become easier for viewers to understand.
