Hamasaki (18-2) became the promotion’s inaugural 108lbs champion when she submitted Jinh Yu at Rizin 16. Her title will not be on the line when she faces the multiple time Muay Thai champion in Nagoya.
Boonsorn (3-1) is better known as ‘Amp’. She is coming off a submission win over Emi Sato at Deep-Jewels 23 which probably put her on the radar of the Rizin matchmakers.
The Rizin 18 card is coming together with multiple matchups revealed yesterday. Haruo Ochi (19-7-2) is currently riding a seven fight winning streak and is the reigning Deep strawweight champion.
He is coming off a decision win at Deep 88 and also tasted victory at Rizin 13. The 35 year old has spent virtually his entire career facing Japanese opponents but faces a different challenge against UFC veteran Jarred Brooks (14-2).
Reigning Deep bantamweight champion Victor Henry (18-4) will make his Rizin debut in Nagoya. The American has been matched with Australia’s Trent Girdham (11-2) in what could turn out to be a title eliminator.
There are several big bantamweight fights on the Rizin 18 card. One of them pits Kazuma Sone (23-18-1) against UFC veteran Justin Scoggins (11-6) in a battle between two men looking to snap losing skids.
As previously announced an all Japanese bantamweight bout between Kyoji Horiguchi and Kai Asakura will headline Rizin 18. It will be the former’s first fight on home soil since winning the Bellator 135lbs title last month.
