Yukio Naya

As the grandson of Taiho, a legendary Yokozuna of the Showa era, and the eldest son of former Sekiwake Takatokoriki, he joined Real Japan Pro Wrestling, founded by the original Tiger Mask, and made his debut in September 2017. With a physique uncommon for a Japanese wrestler, he began competing in other promotions. He made his DDT debut at Ryogoku on February 17 and officially transferred from Real Japan on May 1. He achieved a successful run in the D-Oh GRAND PRIX 2022, finishing as the runner-up, and made his first challenge for the KO-D Openweight Championship in March 2023. He went on to achieve his long-held dream by winning the D-Oh GRAND PRIX 2023. In June 2025, he launched the tag team The Apex with Yuki Iino and won the KO-D Tag Team Championship.
