## History
### Names

| Name | Years |
| Osaka Pro Wrestling Championship | January 4, 2000–January 18, 2019 |
| Osaka Openweight Championship | January 18, 2019–May 1, 2022 |

On January 18, 2019, the title was renamed Osaka Openweight Championship (大阪無差別級王座, Ōsaka Musabetsu-kyū Ōza).
During the COVID-19 pandemic in Japan, Osaka Pro Wrestling (OPW) remained fairly inactive, having held only one event in 2020 and one in 2021. On July 30, 2021, Zeus was appointed as the owner and president of OPW. On August 26, he received a share transfer from former owner Yuji Sakagami. Following the acquisition, OPW underwent a "relaunch" in early 2022. On May 1, a new belt was unveiled and Zeus defeated Kazuaki Mihara to win the title, which was now once again referred to as the Osaka Pro Wrestling Championship.
