Women’s Atomweight

1. Seika Izawa (15-0) | Rizin [1]

Izawa performed as expected at Rizin 49 “Decade,” chaining together multiple submission attempts before tapping out overmatched foe Lucia Apdelgarim with a triangle armbar 2:21 into Round 1 of their non-title bout on New Year’s Eve at Saitama Super Arena in Saitama, Japan. After the bout, Rizin’s reigning super atomweight queen expressed a desire to compete against top international talent in the coming year.

2. Elisandra Ferreira de Oliveira (9-2) | Invicta [2]

Ferreira de Oliveira successfully defended her atomweight crown for the first time in the Invicta FC 61 headliner, taking a five-round verdict over Ana Palacios at the Grand Casino Hotel & Resort in Shawnee, Oklahoma, on April 4. The 27-year-old has won five straight contests within the all-women’s promotion, a run that also includes triumphs over Andressa Romero, Katie Saull, Flor Hernandez and Marisa Messer-Belenchia.

3. Namiko Kawabata (5-4) | Jewels [3]

Kawabata halted a three-fight losing skid with a unanimous decision victory against Saki Kitamura in a super atomweight bout at Deep Jewels 46. By securing her first triumph since September 2022, the 37-year-old Mouri Dojo product maintains her standing in the division.

4. Si Yoon Park (6-4) Jewels [4]

Park’s bid to retain her atomweight belt came up short in the Deep Jewels 44 main event, where she succumbed to a Seika Izawa ninja choke in the second round of their encounter in Tokyo. That setback snaps a five-bout winning streak for the South Korean, who remains the reigning atomweight queen in the Black Combat promotion.

5. Andressa Romero (7-5-1) | Invicta [5]

One bout removed from her upset victory over Deep Jewels microweight queen Saori Oshima, Romero was unable to claim atomweight gold at Invicta FC 57, where she fell to Elisandra Ferreira de Oliveira via unanimous decision at Memorial Hall in Kansas City, Kansas. It marked the second consecutive atomweight appearance for “Gauchinha,” who moved down from strawweight after losing three of her last four outings at 115 pounds.

6. Moeri Suda (13-6) Jewels [6]

Suda secured her third consecutive victory in impressive fashion, submitting Ayaka Hamasaki with a rear-naked choke in the opening stanza of the Deep Jewels 48 main event on March 23. Suda, doesn’t turn 21 until July has vanquished her last three opponents by way of submission and looks like a talent to watch in the years to come.

7. Ayaka Hamasaki (25-7) | Rizin [7]

Facing an opponent less than half her age, Hamasaki succumbed to a first-round rear-naked choke from Moeri Suda in the Deep Jewels 48 headliner on March 23. The 42-year-old Hamasaki, who made a successful return to action following a two-year hiatus in November 2024, has lost three of her last five professional outings but remains one of the most respected names in the division.

8. Saori Oshima (14-5) | Jewels [8]

Oshima suffered an upset loss in her United States debut, dropping a unanimous verdict to converted strawweight Andressa Romero at Invicta FC 55 on June 28. The setback snapped a two-bout winning streak for “Little Giant,” who was coming off a first-round stoppage of Aya Murakami to unify the Deep and Deep Jewels microweight titles in May.

9. Rena Kubota (15-5) | Rizin [9]

Kubota shone at Super Rizin 3 on July 28, busting up Kate Oyama with second-round punches at Saitama Super Arena. While the popular kickboxer remains near the bottom of the Top 10 for now thanks to some head-to-head losses, she figures to have plenty of chances to elevate her stock in the near future, thanks to Rizin’s working relationships with most other promotions with atomweight divisions.

10. Kanna Asakura (20-8) | Rizin [10]

Asakura gave a game effort in a non-title bout against Seika Izawa at Rizin 48, as she defended multiple submission attempts and made her opponent work in a competitive unanimous decision defeat. Afterward, the former Rizin grand prix champion was given a farewell ceremony by the Japanese promotion to honor her retirement. If the decision sticks, Asakura’s rankings eligibility will expire on Sept. 29, 2025.

Other Contenders: Satomi Takano, Chihiro Sawada, Anastasia Nikolakakos, Ana Palacios, Jeong Eun Park.
