From 1990 to 1992 Romero taught karate in Nagoya, Japan at the request of Soshu Oyama. In 1993, Romero was a guest lecturer on martial arts at the Tokyo Institute of Foreign Language Studies.

In 1997 Romero founded Seichou Karate^®in Alexandria, Virginia to help students learn powerful self-defense, achieve a high level of physical conditioning, mental focus and a balanced attitude that would help them achieve success in their everyday lives. The Dojo firmly took root and thrived.

In 2008, Romero opened a 2,100 square foot state-of-the-art facility at 807 North Royal Street in Alexandria. According to our students, Seichou Karate®Dojo is beautiful, serene and conducive to serious martial arts study. The Training Hall is located on the first floor and has a 1,000 square foot unobstructed training mat with a sprung floor, 50-foot mirror, heavy bags, impact pads and crash mats. Also on the first floor are the dressing rooms that are equipped with showers and lockers. On the second floor, we have a classroom where, since 2009, we have offered our unique Kids Interdisciplinary Culture and Karate® program, for cultural arts classes that integrates Japanese language, calligraphy, abacus and flower arranging with karate training for holistic personal development.

In recognition of his tireless efforts to promote traditional Japanese martial arts and culture, on December 1, 2012 the Seichou Karate^®Advisory Committee promoted Romero from “sensei” to the rank of “shihan.”

Shihan (師範) is a Japanese term, often used in Japanese martial arts as an honorific title for expert or senior instructors. The term is frequently used interchangeably with English terms such as “master instructor”.

2016 was bittersweet at Seichou Karate^®Dojo because Romero’s instructor, Soshu Shigeru Oyama passed away in February. However, after paying respects to Soshu, we finished the year strongly with two major accomplishments. First, we opened a second location in the Hollin Hall area of Fairfax County. This satellite dojo has received accolades from the community and we’re delighted to bring authentic Japanese karate and culture to more Northern Virginians. Second, Romero published 121 Thoughts on My Life in Karatedo, which he co-authored rote by with Soshu Oyama. The book describes how Oyama’s experiences growing up in the rubble of post WWII Tokyo motivated him to become one of the most inspiring martial arts masters of the last 100 years, and sets out his philosophy on karatedo and his hopes for the future of traditional martial arts. 121 Thoughts on My Life in Karatedo” is available here.
