Masato Tanaka
Oya made his debut in Frontier Martial-Arts Wrestling in November 1993, under the name Hisakatsu Oya. Unlike his previous stints in NJPW, SWS, and NOW, Oya found his niche. Over the course of a year, Oya proved his worth in FMW, battling the likes of Battle Ranger, Masato Tanaka, Mitsuhiro Matsunaga, and Atsushi Onita.
