Hirata beat Nakajima on the third hole of a sudden-death play-off to claim his first title on the Japan Golf Tour.
The pair had each finished the final round on 17-under par, one clear of Kanaya and Yasumori.
Taiga Semikawa, the only player in the field already exempt for The 151st Open, carded a sensational 63 on Sunday to claim fifth.
