Strongman All Japan Triathlon

The competition integrates three disciplines with a 3-kilometer swim in the East China Sea, 155 kilometers of cycling, and a 42-kilometer marathon run.

The triathlon started in 1984 with 243 participants and expanded to become the largest long-distance triathlon event in Japan, now limiting entries to 1500 athletes.

The competition features a monument in Miyakojima where ceramic plaques display the names of previous winners, preserving the legacy of this athletic event.

Registration opens several months before the April event through the official website, with participants receiving detailed information about accommodation and transportation options.

During extreme weather conditions in 2013 and 2015, organizers modified the competition into a duathlon format by canceling the swimming segment.
