After losing all three pool matches on day one against Ireland, USA and England, the Fijiana bounced back to defeat hosts Japan 28-17 before crushing Spain 41-12 in the playoff for ninth place.
It's Fiji second consecutive ninth place finish under new head coach Saiasi Fuli, who was appointed in December.
Fiji remain in 10th place in the overall World Series standings after four of six legs, three points behind the Spaniards but a whopping 21 points adrift of the top eight.
