Good Gosh...how did we miss this one?

"Lynn Matsuoka, of Honolulu and Tokyo, fell in love with sumo and spent the last 22 years documenting the ritualistic lives of the giant wrestlers of Japan's national sport. She trained as a reportage artist at Tyler School of Art in Philadelphia, and the School of Visual Arts in New York. She gained experience with many subjects, from Watergate characters for television, to New York Yankee ball players, from high fashion in New York to new fashion and ancient kabuki theatre in Japan.
When Lynn discovered sumo, she made her home in Tokyo. She decided to develop her skills in oil pastel, a medium that allows her to create images of the rikishi (sumo wrestlers) quickly, in the dressing room and in the dohyo (sumo rink), without requiring them to stop and model, without making a big display of her presence. However, being a woman among 800 sumo wrestlers-from lowly trainees at the sumo stable, to yokozuna (grand champions)-could only draw attention to Lynn Matsuoka. She soon became a novelty in Japan, interviewed by newspaper and television reporters and invited to galleries to exhibit her work. Making her even more visible in the sumo world, after four years of documenting the sport, she fell in love with Iwatora, a top-division wrestler, married him upon his retirement and produced two sons."
