Barron has referenced his love for the sport and lack of other options in Hawaii as being principal motivating factors in his pursuit of surfing.
He has continued to pursue a career in professional surfing, attributing his success to his perpetual hunger to push and prove his abilities to both himself and his peers.
These achievements improved his ranking heading into the 2018 season in which he competed in eight events, with his career best result coming at the Burton Automotive Pro in Australia, where he lost to Mikey Wright in the final.
His most recent qualifying tour event, the Sunset Open in Hawaii, resulted in fourth place in late January 2018.
Prior to the event, in an interview with Michael Ciaramella from Stab magazine Mamiya stated that he felt "no pressure at all" and appreciated the opportunity to express himself free from the usual weight of expectation.
[1] Mamiya's first major highlight in the CT was in 2022 when he won the second stage of the year, the Hurley Pro Sunset Beach, beating Kanoa Igarashi in the final.
In the 2025 season, Mamiya made history once again, defending the champion title against Leonardo Fioravanti at Pipe, joining a select group of multi-champions at Pipeline.
The film both interviewed him about his early exposure to surfing, retelling the story of how he "fought his way into the Pipeline pecking order" and became "a face of the future."
Produced and directed by his manager Shaun Ward and filmed by Michael Ikalani, Peter King, Rory Pringle, the video displays the surfer's highlights from the Men's Junior Tour of 2017.
Released in May 2018 for Surfer magazine and Varial Surf Technology the clips demonstrate his "well rounded, progressive…smooth style" in his home break – the North Shore.
