FMW - Atushi Onita, founder of FMW (Frontier Martial Arts Wrestling) had a concept. On July 22, 1990 a ring was set up in the Miyazaki Nichinan Sea close enough to land for fans to still be able to come and watch the show.

A 13-Man battle royal ended the show with the wrestlers being eliminated by thrown into the water. Wrestlers had to swim back to land after being eliminated. Ricky Fuji won the battle royal.
