Alongside her brother (Norifumi Yamamoto) and sister (Seiko Yamamoto), she was trained by his father at an early age.

Since her childhood, Miyuu was raised in a wrestling environment. Later it helped Yamamoto to establish herself as a decorated female wrestler.

When she was 13 years old, only Yamamoto won the 1st Japan Women’s Championship. Later she defended her title for four consecutive years.

However, Yamamoto couldn’t represent Japan in World Championship due to the age limit. 


Miyuu Yamamoto is the eldest child of their parents. She has a younger sister Seiko Yamamoto and had younger brother Norifumi Yamamoto who sadly passed due to cancer.  

Seiko Yamamoto

Seiko Yamamoto is a 40 years old Japanese wrestler like her sister Miyuu Yamamoto. She began her wrestling training at just the age of three.

She is also a four-time World Wrestling Champion and two-time Asian Wrestling Champion. Seiko made her professional debut in 1999 and retired in 2009. 

Norifumi Yamamoto

Norifumi Yamamoto was a Japanese MMA fighter and kickboxer. At first, just like his sisters, he was a wrestler too.

But Norifumi, at age 21 years old, made a transition into MMA. Norifumi was firstly trained by Enson Inoue, who was Yamamoto’s fiance at that time.

Noifumi competed in different MMA promotion companies like Sotto, Hero, and Dream before making his way to UFC.

He made his UFC debut in 2011 and competed in the bantamweight category. Norifumi holds a UFC record of 18-6-2.

Norifumi was diagnosed with cancer in 2016. He died on 18th September 2018 because of stomach cancer. 

At the beginning of Miyuu MMA’s career, Norifumi was her first coach. He was the first sibling to start wrestling first.

Miyuu Yamamoto | Career


Before MMA, Yamamoto had already made an impressive resume in the Wrestling world. She became the youngest and 3-time world champion during her wrestling career.

During her career, Yamamoto took many breaks, maybe because of marriage and pregnancy.

World Wrestling Championship

When Yamamoto was 17, she participated in her first world championship and won it. For Yamamoto’s first championships, she competed in 47 kgs and defeated Pan Yanping from China. 

Yamamoto is the youngest World Wrestling Champion.

Later in 1994 and 1995, Yamamoto became world champion in the 50 kgs and 47kgs categories, respectively. 

In 1995 Yamamoto took her first retirement. But returned temporarily in 1999 and participated in Queens Cup. She also won Asian Championship and All Japan Women Championship in the same year. 

Zero Appearance in Olympics

After retiring in 2000, Yamamoto returned to active service in 2004. Women wrestling became an official Olympics event for the first time in 2004, during the Athens Olympics.

But Yamamoto secured the third position in the selection tournament known as Japan Queens Cup. So she could not participate in the Olympics.

In 2011 Yamamoto again returned to Wrestling. She intended to participate in the 2012 London Olympics.

Similarly, Yamamoto won The All Japan Women Open Championship in October. But in the selection tournament, she lost in the second round.

After acquiring Canadian citizenship in December 2015, Yamamoto aimed to compete in Rio Olympics 2016.

Even though Yamamoto was a Canadian citizen, she couldn’t participate in the Olympic trials. So, after 2016 she decided to compete in MMA, leaving wrestling behind. 

Sports Caster

Yamamoto also worked as a sportscaster in the Sports Biz group. She worked as a sportscaster while taking a break from wrestling.

Yamamoto was also a leader of Kids Wrestling, which was organized by the Japan Sports Network.

Mixed Martial Artist 

At the age of 42, Yamamoto signed with RIZIN Fighting Federation in 2016. Even at old age, she accepted a new challenge and has shown the highest level of competitiveness.

Yamamoto has performed exceptionally well in sports; she is starting as a rookie. 

Yamamoto made her RIZIN debut on 25th September 2016 against Rena Kubota in the Rizin Fighting World Grand Prix. She lost in the first round by submission.

In Yamamoto’s debut, her son also competed. It was the first time in RIZIN history that mom and son fought on the same card.

Yamamoto suffered a back-to-back loss after Andy Nguyen defeated her on 31st December 2016 by Technical Submission.

Finally, on 30th July 2017, Yamamoto registered her first victory in RIZIN FF. She defeated Cassie Robb by unanimous decision.

In the next fight against Irene Cabello Riveria on 15th October 2017, she suffered defeat by submission.

Things didn’t go quite well for Yamamoto in her RIZIN career. She started with three wins and one loss. It was not a surprise because she competed in the blooming atom weight division. 

Four Fight Winning Streak

After her loss against Irene, Yamamoto started her longest win streak in RIZIN with four wins. Yamamoto firstly defeated Saori Ishioka on 28th July 2018 with a split decision.

Later, on 30th September 2018, Yamamoto defeated Andy Nguyen, who she previously lost in her second fight. She won the fight by unanimous decision.

After that, on 31st December 2018, Yamamoto defeated Mika Nagano also by a unanimous decision.

Later in her next fight, she got one of the biggest wins in her career after she defeated the top 5 rank atom weight, Kanna Asakura, by unanimous decision.

Yamamoto’s amazing four-win streak kept her first title fight opportunity. She was just one win shy of it.

Unfortunately, she was defeated by TKO in her next fight against experienced Korean fighter Seo Hee Ham (punches). 

On 31st December 2019, Yamamoto defeated Suwanam Boonsorn by a unanimous decision. To date, it’s her last win in RIZIN FF. 

Title Fight

On 31st December 2020, Yamamoto finally got the title shot for the vacant RIZIN FF super-atom weight title. Yamamoto was set to face her career’s biggest fight to date.

Also, she was about to face former titleholder Ayaka Hamasaki. Sadly, Yamamoto was defeated in the first round by submission. 

Yamamoto’s defeat to Hamasaki was her last appearance in RIZIN FF before the Covid 19 pandemic spread worldwide.

During this pandemic, Yamamoto didn’t take a rest and devoted herself to improving her MMA skills. Overall since her debut back in 2016, Yamamoto presently holds a 6-5 record in MMA.
