ONE SAMURAI 1 Adds Four More Bouts Including World Title Fight

ONE Championship has revealed four more matchups for ONE SAMURAI 1. The event goes down live on Wednesday, April 29, from the iconic Ariake Arena in Tokyo, Japan.

Reigning ONE Atomweight Muay Thai World Champion Nadaka Yoshinari makes his first title defense against Thai challenger Songchainoi Kiatsongrit, Shimon Yoshinari takes on Malaysian-American superstar Johan Ghazali in a flyweight Muay Thai clash, Hiromi Wajima meets Ricardo Bravo in a featherweight kickboxing contest, and Toki Tamaru faces Toma Kuroda in an atomweight kickboxing showdown.

The announcements were made at the ONE SAMURAI 1 Kickboxing Press Conference in Tokyo, Japan, this past Monday, March 30.

ONE SAMURAI 1 already features the rematch between Takeru Segawa and Rodtang Jitmuangnon for the ONE Interim Flyweight Kickboxing World Title. Also, ONE Flyweight MMA World Champion Yuya Wakamatsu defends his belt against Avazbek Kholmirzaev, and ONE Bantamweight Kickboxing World Champion Jonathan Haggerty puts his gold on the line against Yuki Yoza.

Nadaka Puts Atomweight Gold on Line Against Songchainoi at ONE Samurai 1

Nadaka has packed more achievement into his career than most fighters manage in a lifetime, and the 25-year-old is still only getting started. The Eiwa Sports Gym product holds a remarkable 66-6 career record and owns a collection of titles that includes the Rajadamnern Stadium and Lumpinee Stadium Muay Thai World Titles, alongside WMC and WBC Muay Thai World Titles.

He made his ONE debut in 2025, won three consecutive bouts to earn a title shot, and then outclassed Numsurin Chor Ketwina in front of his home crowd at ONE 173 to claim the inaugural ONE Atomweight Muay Thai World Title.

Songchainoi arrives with credentials of his own. The 25-year-old Thai from Kiatsongrit Muay Thai Gym carries a 60-18 striking record and a 10-1 promotional mark built on a nine-fight win streak that earned him a six-figure ONE Championship contract after just five appearances. Now, he is motivated to win gold at ONE SAMURAI 1 and get revenge against the man who beat him three years ago.

Shimon Takes on Johan Ghazali in Flyweight Muay Thai Clash at ONE Samurai 1

Nadaka’s cousin, Shimon, is one of the most consistent performers on the ONE Championship roster. The 21-year-old Japanese technician from EIWA Sports Gym carries a 25-1 career record and has gone unbeaten in ONE, compiling four victories and one no contest since his promotional debut.

His technical approach and methodical striking style have allowed him to navigate every challenge the division has thrown at him, and a win over a name as prominent as Ghazali would represent the biggest statement of his career to date.

Ghazali brings a story that continues to captivate ONE Championship fans worldwide. The 19-year-old Malaysian-American sensation out first arrived in the promotion at 16 years old, winning his debut in 16 seconds before adding four more victories to claim a coveted main roster contract.

Two More Kickboxing Bouts Added to ONE SAMURAI 1

Hiromi Wajima brings serious striking credentials to his second ONE Championship appearance in ONE SAMURAI 1. The 31-year-old Japanese fighter trains out of Shika Gym and is a multi-time K-1 Champion with a 22-7 career record, which includes 18 knockout victories. He made his ONE debut in a featherweight kickboxing contest against former ONE Bantamweight Muay Thai World Champion Nabil Anane, a tough outing that ended in a unanimous decision loss.

Bravo, 26, carries a 27-4 striking record and a 3-2 ONE mark. Three highlight-reel finishes at ONE Friday Fights earned him a main roster contract before back-to-back losses brought his momentum to a halt. The Argentine arrives in Tokyo desperate to prove those results were a temporary setback rather than a sign of things to come.

The atomweight kickboxing clash between Tamaru and Kuroda adds an all-Japanese flavor to the card. Tamaru, 24, makes his ONE debut in front of his home crowd. Kuroda, 25, fights out of Forward Gym and holds 15 career wins. A convincing performance from either man on Japanese soil could serve as the launching pad for a deeper run in the atomweight kickboxing division.

ONE SAMURAI 1 takes place on Wednesday, April 29, at Ariake Arena in Tokyo, Japan. Stay tuned to MMASucka for full broadcast details as they are confirmed.
