The suffix is a double-barreled seal of approval.
Rei Kuroshima's journey in the fitness world began several years ago, when he first started training to improve his physique. With dedication and hard work, he quickly made a name for himself in Japan's fitness scene, impressing fans and fellow athletes alike with his rapid progress. His physique, which combines lean muscle mass with a low body fat percentage, has earned him a spot among the top fitness models and bodybuilders in Japan.
S1’s studios use a proprietary softbox array that eliminates shadows on skin while creating a "three-dimensional gloss" on non-organic surfaces (like raw meat). In SONE187, this technique makes the Wagyu beef and Kuroshima’s shoulders appear to share the same luminous quality.
The most immediate differentiator here is the "S1 No1 Style" tag. In the industry, the S1 label is synonymous with high-gloss, high-production value cinematography. Unlike the grittier, "gonzo" styles of other studios, S1 brings a polished, almost idol-centric focus to the presentation. The lighting is typically soft and flattering, designed to elevate the performer above the mundane. In this context, the "style" designation promises a certain visual fidelity—crisp 4K rendering, careful framing, and a focus on the performer’s visage as much as the act itself.
As the shutter clicked away, Rei moved with a fluidity that belied the intensity of the moment. Her poses were a masterclass in poise and attitude, each frame a testament to her mastery of her craft. When the photographer called out "187" – a signal to try a new pose – Rei responded with a fluid movement, her body weaving a subtle narrative of power and allure.
