On October 4, 2015, UPW held its last show, celebrating its 10th anniversary. On October 7, Kodaka announced the formation of a new promotion that would replace UPW, named Pro-Wrestling Basara. The name "Basara" reads either as or and, according to Kodaka, relates back to the kabukimono which were gangs of samurai who dressed in flamboyant clothing and donned uncommon hairstyles. Basara was founded to "do something rebellious against the new, flashy style of wrestling". The Union Max Championship, formerly the top prize in Union Pro, was kept to be contested as the only singles championship in Basara.

In October, the third edition of the annual "Iron Fist Tag Tournament" led to the creation of Basara's first tag team championship, the Iron Fist Tag Team Championship. Since its independence, Basara has had partnerships with other Japanese promotions such as Dove Pro Wrestling or Wrestling of Darkness 666, and has used the UWA World Trios Championship as its trios title along with Big Japan Pro Wrestling.
On June 9, 2025, Kodaka stepped down from his position as president of the company due to the promotion's struggles in attracting audiences. Ryota Nakatsu subsequently became president, while Kodaka remained the company's representative.
