Yoshiko

Yoshiko Hirano (平野 芳子), known mononymously as Yoshiko (世志琥), is a Japanese professional wrestler.

She is currently working for Seadlinnng.

Hirano was presented as part of World Wonder Ring Stardom's roster at the promotion's first press conference on September 7, 2010.

She was trained by Fuka Kakimoto alongside the likes of Eri Susa, Mayu Iwatani, Yoko Bito and Yuzuki Aikawa as part of Stardom's first class of trainees.

Hirano was given the ring name Yoshiko, spelled with the Roman numeral for the number four, IV, read as "shi".

She was given a villainous character, inspired by the yankii culture.

She debuted with the World Wonder Ring Stardom promotion in January 2011, forming a successful partnership with Natsuki☆Taiyo, with the two winning the Goddess of Stardom Championship and the 2012 Goddesses of Stardom Tag League.

Her debut match took place at Stardom's inaugural event on January 23, 2011, where she was defeated by Yoko Bito.

Afterwards, Yoshiko formed a partnership with veteran wrestler Natsuki☆Taiyo.

The team was named "Kawasaki Katsushika Saikyou Densetsu" ("Kawasaki [Taiyo's birthplace] Katsushika [Yoshiko's birthplace] Strongest Legend").

On July 24, Yoshiko was part of a match to determine the inaugural Wonder of Stardom Champion, but was defeated by Yuzuki Aikawa.

On November 27, Yoshiko and Taiyo were defeated by Aikawa and Bito in the finals of the 2011 Goddesses of Stardom Tag League, which was used to determine the inaugural Goddess of Stardom Champions.

Yoshiko ended the year by winning a four-woman tournament contested between the class one trainees to become the 2011 Rookie of Stardom.

Yoshiko and Taiyo eventually won the Goddess of Stardom Championship on November 25, 2012, by defeating Kairi Hojo and Natsumi Showzuki in the finals of the 2012 Goddesses of Stardom Tag League.

Meanwhile, Kawasaki Katsushika Saikyou Densetsu expanded into "Kawasaki Katsushika Saikyou Densetsu Plus One" with the additions of Act Yasukawa, Kyoko Kimura and Saki Kashima.

After three successful title defenses, Yoshiko and Taiyo lost the Goddess of Stardom Championship to former stablemate Kyoko Kimura and Hailey Hatred on March 17.

On April 29, Yoshiko main evented Stardom's Ryōgoku Cinderella event, defeating Yuzuki Aikawa in her retirement match.

On October 17, Yoshiko took part in a sixteen-woman elimination tag team match, promoted by Sendai Girls' Pro Wrestling.

The match pitted a team of younger wrestlers against a team of industry veterans.

Yoshiko won the match for the younger generation by scoring the final elimination over Sendai Girls' founder Meiko Satomura.

Following Taiyo's retirement, Yoshiko won Stardom's top title, the World of Stardom Championship, in August 2014.

Back in Stardom, Yoshiko continued teaming with Taiyo until her retirement in June 2014.

On the road to her retirement, Taiyo was defeated by Yoshiko on March 16 in what was billed as the final match between the teacher and student pairing.

After going solo, Yoshiko won Stardom's top title, the World of Stardom Championship, by defeating Io Shirai on August 10, 2014.

Afterwards, Yoshiko came together with Shirai, Mayu Iwatani and Reo Hazuki to form a group of wrestlers born in the Heisei period, opposing a team of Stardom's older wrestlers, led by Nanae Takahashi.

Yoshiko's reign ended in controversy in February 2015, when she went off script during a match with Act Yasukawa, legitimately beating and injuring her.

Afterwards, Yoshiko was out of the World of Stardom Championship, suspended and eventually announced her retirement.

On January 18, 2015, Yoshiko successfully defended the World of Stardom Championship against Takahashi.

On February 22, 2015, Yoshiko faced former stablemate Act Yasukawa in her third defense of the World of Stardom Championship.

The match saw Yoshiko go off script, legitimately beating Yasukawa until veteran wrestler Kyoko Kimura threw in a towel to end the match after less than eight minutes.

Afterwards, Yasukawa was diagnosed with fractured cheek, nasal and orbital bones, which required surgery.

Yasukawa had had issues with her eyes before the incident, having undergone a cataract surgery the previous year.

On February 25, Stardom held a press conference, during which Yoshiko publicly apologized for the incident, after which she was stripped of the World of Stardom Championship and suspended indefinitely.

The incident received mainstream attention in Japan and became known as Seisan Matchi (凄惨マッチ).

The incident also strained the relationship between Stardom's management and top wrestler Nanae Takahashi, leading to Takahashi quitting the promotion in May.

On May 31, Stardom announced that Yoshiko had decided to retire from professional wrestling.

Her retirement ceremony took place on June 14, however, during the closing ten-bell salute meant to signal the end of her career, Yoshiko walked out on the ceremony, leading to questions over whether she was truly retired.

Yasukawa eventually returned to the ring on September 23, 2015, but retired the following December due to the damage inflicted on her eye in the incident with Yoshiko.

However, she soon returned to professional wrestling, and in February 2016, started working for Nanae Takahashi's new promotion Seadlinnng.

She later made a special appearance at All Star Dream Cinderella, in a match against Mayu Iwatani.
