Wrestle Princess IV

Wrestle Princess IV was a professional wrestling event promoted by CyberFight's sub-brand Tokyo Joshi Pro-Wrestling. It took place on October 9, 2023, in Tokyo, Japan, at the Tama Mirai Messe. The event aired on CyberAgent's AbemaTV online linear television service and CyberFight's streaming service Wrestle Universe.

It was the fourth annual event under the "Wrestle Princess" branch, which is considered to be Tokyo Joshi Pro-Wrestling's yearly main pay-per-view.

Storylines
The event featured ten professional wrestling matches that resulted from scripted storylines, where wrestlers portrayed villains, heroes, or less distinguishable characters in the scripted events that built tension and culminated in a wrestling match or series of matches.

Event
The event started with two preshow matches broadcast live on TJPW's YouTube channel. In the first one, Runa Okubo defeated Haru Kazashiro in singles competition, and in the second one, Arisu Endo, Himawari and Kaya Toribami defeated Harukaze, Riara and Yoshiko Hasegawa in six-way tag team action.

In the first main card bout, Moka Miyamoto defeated Juria Nagano. Next up, Aja Kong, Raku and Shino Suzuki picked up a victory over Hyper Misao, Toga and Wakana Uehara.

In the sixth match, Martha, Mei Saint-Michel, Sakisama and Yukio Saint Laurent defeated DDT Pro-Wrestling's representative Antonio Honda and Pom Harajuku, Shoko Nakajima and Suzume. The bout symbolized the end of the Neo Biishiki-gun stable, as well as Sakisama's last TJPW appearance before her retirement match which was scheduled to take place at Ultimate Party 2023 later that year. Next up, All Elite Wrestling's Nyla Rose picked up a win over Maki Itoh in singles competition. In the eighth bout, Hikari Noa and Nao Kakuta defeated Mahiro Kiryu and Yuki Kamifuku to win the vacant Princess Tag Team Championship, titles relinquished three months prior to the event due to Yuka Sakazaki suffering an injury. In the semi main event, Max the Impaler defeated Rika Tatsumi to win latter's International Princess Championship in a winner takes all bout which was also disputed for Max's NWA World Women's Television Championship.
